The main purpose of the reconnaissance study is to evaluate the nature of the resource and determine if there is potential for electricity generation to serve the communities of Pelican and Hoonah. The resource is located near the head of Tenakee Inlet on northern Chichagof Island, in southeast Alaska. The resource is characterized at the surface by at least four small hot springs that occur together on the southeast side of the Tenakee Creek located at approximately 57° 59° 24” N and 135° 56° 20” W. These hot springs have been scientifically documented in several geologic publications since at least 1980, and tested for minerals and temperature. The reported surface temperature of the springs is 176°F with geochemistry of the waters indicating a maximum subsurface temperature of 243°F. The Tenakee Inlet Geothermal Resource Project started in August 2011 after notice of award. The project was funded through a renewable energy grant administered by the Alaska Energy Authority (AEA). Hattenburg Dilley & Linnell (HDL) was contracted by Inside Passage Electric Cooperative (IPEC) to manage the project and conduct field studies and evaluation of the geothermal resource. This interim report presents a description of the project, field explorations, and the laboratory and geological analysis conducted as of December 2011. 2.0 PROJECT DESCRIPTION The Tenakee Inlet Geothermal Resource is located approximately 19 air miles southwest of Hoonah Alaska along an un-named river we have called Tenakee Creek. Figure 1 presents a vicinity map. The area is characterized by rugged, steep terrain covered with thick vegetation typical of southeast Alaska rainforest. The topographic highs limited the exploration area to the valley floors and to the first bench above the river valley. The resource surface expression consists of four small hot springs that occur at the base of a slope on the southeast side of Tenakee Creek. The hot springs area is small about 50 feet long by 20 feet wide. The focus of the study area was the immediate hot springs area and approximately ‘4 to 2 square mile surrounding the hot springs. Figure 2 presents an aerial photograph of the study area. There are two boundary streams that bounded the study area on the southwestern side and northeastern side. A Special Use Permit from the US Department of Agriculture, Forest Service was obtained. The permit allowed HDL to conduct the fieldwork at the hot springs location and the surrounding areas. Coordination with the Forest Service personal were conducted due to bear hunting season and potential conflicts with bear guides. An operations plan Iterim Report — / 1 ADIL ares user a unnens Tenakee Inlet Reconnaissance was established for the orderly acquisition of field data, with provisions to flex the plan as conditions dictated. Due to the remoteness of the investigation area and the vagaries of weather in southeast Alaska, a “survival camp” was equipped and stored near the hot springs, sufficient to provide emergency shelter and food for the team for several days if off-site transport was to become unavailable. Fieldwork consisted of collecting shallow temperature data, and soil, water and rock samples from various locations surrounding the hot springs and the immediate vicinity. A grid was established to systematically collect temperature data and soil samples. Water and rock samples were more varied and were dependent upon the location of the samples to the hot springs. 3.0 REGIONAL CHARACTERISTICS Chichagof Island is dissected by numerous bays, inlets, and fjords with an irregular shoreline. Numerous short streams with steep gradients occur on the island. Flow is highly variable throughout the year and the streams respond rapidly to precipitation. Glaciation has significantly altered the landscape. 3.1. General Geology The Tenakee Inlet area is composed of Devonian age argillite, graywackes and limestones that were subsequently intruded by wide variety of igneous rocks. These rocks outcrop near the study area and to the north of the study area. Figure 3 presents a geologic map of the area. The intrusives vary in age but are primarily Cretaceous and in the study area and are mainly diorite to granodiorite in nature. These rocks are widely distributed on Chichagof Island. On Figure 3 these rocks are represented in yellow with a Kd symbol. To the south of the study area is a large body of Tertiary intrusives consisting of hornblende leuoconorite and troctolite. The Devonian age sedimentary rocks have undergone extensive regional and contact metamorphism. The intrusives have metamorphosed the sedimentary rocks into hornfels, and marbles. On Figure 3 these rocks are represented by Pzh/Pzm symbol and occur to the northwest of the study area. The rocks are intensely folded and faulted. The fold axes trend northwest. 3.2 Structural Geology The structural geology of the area is dominated by the Queen Charlotte-Fairweather fault system and the Chatham Strait Fault. The Queen Charlotte-Fairweather fault system lies to the immediate west of Chichagof Island and the Chatham Strait Fault defines the Chatham strait between Chichagof Island and Admiralty Island to the east. The faults of the Queen Charlotte-Fairweather system are active right-lateral structures with large displacements. The Chatham Strait Fault offsets rocks as young as middle Tertiary and by as much as 90 miles. (Gehrels & Berg 1994). The Queen Charlotte-Fairweather fault system defines the plate boundary of the Pacific plate and North America. In the middle Mesozoic prior and/or concurrent with the SEE Re ee connel 2 HOD sue Tenakee Inlet Reconnaissance intrusion of the igneous rocks in the study area, southeast Alaska was involved in subduction of the Pacific plate beneath North America (much like the present day Aleutian Trench), which over time evolved into the dominant transform plate boundary seen today (similar to the California San Andreas Fault system). This tectonic activity has resulted in a complicated patter of thrust faults, oblique slip faults, and strike-slip faults on Chichagof Island (Figure 3). The major faults define micro-plates termed tectonostratigraphic terranes. The rocks in the study area are part of the Alexander terrane. Based on paleomagnetic, structural, and stratigraphic data, the Alexander terrane has moved northward relative to its original sites of deposition and to North America. The rocks of the Alexander terrane are interpreted to represent intermittent volcanic arc activity and the terrane is inferred to have continental origins (Karl 1999). Modern earthquake activity occurs along the Queen Charlotte-Fairweather fault system. The most recent large magnitude earthquakes in the area of the hot springs occurred in 1939 and 1927. A magnitude 6 occurred in 1939 at latitude 58.00 and longitude -136.0. A magnitude 7.1 occurred in 1927 at latitude 57.69 and longitude -136.07. The hot springs are located at latitude 57.99 and longitude -135.939. 3.3. Climate Climate in the region is typical of southeast Alaska with a maritime climate characterized by cool summers and mild winters. Foggy periods typically occur in the spring and fall. Summer temperatures in Hoonah average 52 to 63 °F; winter temperatures average 26 to 39 °F. Temperature extremes have ranged from -25 to 87 °F. Precipitation in Hoonah averages 100 inches annually with 71 inches of snowfall. Tenakee Springs located to the south of the project area has slightly cooler summer temperatures and less precipitation. Total precipitation averages 69 inches a year with 62 inches of snowfall. During our fieldwork we established a small weather station at the base camp near the hot springs location. The temperatures in late September — early October ranged from 36 to 48 °F. Precipitation occurred on 6 of the 15 field days and ranged from 0.04 inches to 1.02 inches. The 1.02 inches occurred on September 28, 2011 the day after the 0.04 inches. The rainfall was recorded at 10:30 am. 3.4 Topography Chichagof Island is fairly mountainous and of moderate relief. Major peaks reach a height less than 4,000 feet. Although glaciation has modified the landscape there is only one present-day glacier on Chichagof Island. The ice sheet during the Pleistocene covered all but the highest elevations on the island and minimum elevation was between 2,400 to 2,700 feet. In the mountainous terrain glacial erosional features such as cirques, horns, arétes, and U-shaped valleys occur. These glacial features have been further modified by steep gradient streams creating V-shaped river valleys such as Tenakee Creek. Dense forests occur throughout the island. Hemlock and spruce are the dominant forest trees. The dominant undergrowth of alder, devilsclub, and berry bushes is nearly Iterim Report — 3 HI eee este Tenakee Inlet Reconnaissance impenetrable in places. Timberline various but generally ranges from 2,000 to 2,600 feet on Chichagof Island. The hot springs occur at the base of a vegetated slope on a gravel bar. The gravel bar has approximately 10 foot elevation change across the 200 foot width. Spruce, hemlock and alder occur on the gravel bar which is approximately 600 feet long. The slope rising from the hot springs to the southeast has a gain of approximately 200 feet in about 300 feet horizontal distance. There is a steeply incised creek canyon named Stairway to Heaven by the field team located approximately 50 feet east of the hot springs. Freshwater from the slope flows from this creek and mixes with the hot spring outflow which meanders to the east along the base of the slope towards Tenakee Creek (Figure 4) Across Tenakee Creek to the northwest from the hot springs, the river canyon slope rises approximately 100 feet over 160 feet. At the top of these slopes is a gentler slope composed of wetland vegetation with some trees (Figure 4) 3.5 Hydrology Tenakee Creek has a watershed of approximately 27 square miles, ranging in elevation from Pegmatite Mountain at 3,500 feet to sea level at the mouth. The watershed includes glaciers, tarn lakes, steep mountain slopes, U-shaped glacier-carved valley walls, steeply incised narrow canyons, waterfalls and broad sloping muskeg terrain. In the vicinity of the hot springs the creek flows in a channel ranging from 30 to 80 feet wide, depending on flow. Depths ranged from one to four feet, with some pools deeper than five feet at scattered intervals along the creek. From a mile upstream to just below the hot springs area, Tenakee Creek is incised in a steep-walled canyon ranging from 100 to 250 feet deep and about a quarter mile wide. Flow rates and volumes are not available for Tenakee Creek, but one observed fact is that the drainage is extremely and rapidly responsive to local rainfall. During the course of the investigation, the creek was observed to rise rapidly and fall rapidly, apparently in direct response to rainfall events. In one 24 hour event (Wednesday 28 Sept 2011) with 1.02 inches of recorded rainfall, the river rose at least 2.5 feet in the vicinity of the hot springs, then subsequently receded one foot the day after, another half-foot the second day after. The rise in river level was so rapid on that occasion the landing zone flooded and crew had to be evacuated on short notice. The hot springs bubble up into a small pool which drains out through a 400 foot-long channel along the base of the steep valley wall, parallel to and then merging with Tenakee Creek (Figure 4). When creek flow was high (near the vegetation line on the river bank), the hot spring outflow was discharging directly into the creek. However when the Tenakee Creek level dropped to 2 to 3 feet below the vegetated riverbank, outflow in the spring channel ceased. At the same time, vapors were observed welling up from the exposed creek bed, particularly in the area slightly downstream of the hot springs. Numerous small outflows were observed within the creek sediments, and the rocks and sand deposits were warm to the touch. It is likely that the coarse floodplain Iterim Report - 4 HDD ipeon omanon Tenakee Inlet Reconnaissance sediments are quickly flooded then drained in concert with the creek level. This rapid response alternately constrains the outflow to its channel when the creek is high, then facilitates a lateral flow of hot spring water toward the creek bank when low. These small outflows were termed seeps and alternately may represent springs not directly connected to the outflow. 4.0 METHODS Fieldwork began on September 21, 2011 was completed on October 9, 2011. HDL’s six- man field team was based out of Hoonah and supported with full-time helicopter transport provided by Coastal Helicopters. The field team consisted of two surveyors, one professional engineer to evaluate site conditions, and three geologists. Several landing zones were established and used for the majority of the field efforts; additional one-time landing spots were determined by the helicopter pilot as needed. A grid was developed based on 300 feet by 300 feet squares prior to the fieldwork. This grid and study area proposed was condensed due to topography, vegetation, and subsurface temperature information obtained. Three survey control points were established (two near the hot springs and one on the east side hill) in order to maintain accurate survey control for future fieldwork and development. A rectangular grid was then established from the base line onto the surrounding hot springs area. GPS coordinates were collected at grid points. The grid points were used as the locations to collect the soil samples and install the shallow temperature probes. The field crew started from the hot spring location and work outward in a spiraling pattern to gather the field data, with tightly-defined 100 foot spacing nearest the hot spring, then expanding to 300 ft spacing. The grid baseline was define as “A” and was aligned through the hot springs. The hot springs occurred at grid point “A4”. At the conclusion of the 15 day field effort, the team had established over 120 grid points. Eighty-four temperature readings were obtained; and 37 water samples, 63 soil samples (plus a number of duplicate samples), and 7 rock samples were collected. Table 1 presents the samples obtained, the laboratory used for analysis and the location of the samples obtained. Samples were submitted to respective laboratories for analysis. From September 27 through September 30, Lorie Dilley of HDL and Joe Moore, a geothermal researcher with Energy & Geoscience Institute (EGI) visited the site and made some revision in the collection points and sampling intervals in accordance with the temperature findings and the discovery of hot seeps into the main river. HDL’s engineer talked with the Alaska Department of Transportation and the Forest Service in order to determine potential alignments for the access road and transmission line. Potential alignments were observed from the air and the forest service roads were drove to observe the topography, drainage, avalanche slopes and other potential issues for future development. General site characteristics were obtained in order to develop a conceptual plan for development of the site. Iterim Report — 5 HDL erooueemen Tenakee Inlet Reconnaissance 4.1 Field Work 4.1.1 Shallow Temperature Survey The shallow temperature survey used steel pipes as probes inserted into the ground surface and a thermistor installed. The equipment included 5-1/2 foot long sections of 3/4” steel pipe for probes, RTD (Resistance Temperature Detector) temperature measuring devices, demolition hammers for driving probes 5 feet into the ground, and data loggers/meters to record the temperature measured by the RTD. The steel pipe was fabricated into a probe to insert in the ground by welding one end closed and hard facing it to allow it to penetrate hard ground. Forty probes were fabricated and reused during the field work. The field work involved inserting the steel probes in the ground, waiting for equilibration, installing thermistors, and measuring the temperature at the bottom of the hole, then moving the probes to a new location and repeating. Readings that indicated higher temperatures were remeasured. It took approximately 1 to 2 hours for the thermistors and ground disturbance to equilibrate. 4.1.2 Selective Extraction Geochemical Analysis A selective extraction geochemical study of a select area near the hot springs was conducted. The selective extraction geochemical study consisted of obtaining samples from the B soil horizon and conducting Enzyme Leach and Terrasol selective digestion on the soil sample. The method relies on the fact that geothermal systems, like mineral deposits, have at the surface a number of elements that get distributed around the margins of the system. Trace elements can be trapped in amorphous oxide coatings on sand and silt grains in soil near the surface. Enzyme leach and Terrasol digest these coatings and releases the trapped trace elements. An analysis of the sample is conducted for up to 68 trace and major elements by ICP-Mass Spectrometry. The concentrations of these elements are mapped and distinct patterns indicate areas of interest. Sampling consisted of using a clean spoon to obtain soil from a hole excavated below the organic layers. Care was taken to maintain clean spoons and sampling equipment. The shovel used to sample was wiped clean after each sample and pushed into the immediate soils several time to help eliminate cross-contamination from a prior sample. An approximately 25 gram sample collected using a stainless steel table spoon was placed in a 50 ml plastic tube that was supplied by the laboratory. The samples were typically fine- grain. Care was taken to avoid and/or eliminate particles larger than about coarse sand. Of the 63 soils sample collected 27 duplicate samples were taken at select areas and two samples were collected at random locations outside of the geothermal area. 4.1.3 Water Sampling Water samples were collected for chemical analysis from the hot springs, and Tenakee Creek. Additional samples were collected upstream and downstream of the hot spring Iterim Report — : 6 HO ee Tenakee Inlet Reconnaissance location and from the two boundary streams. Water samples were also collected from the springs every couple of days to evaluate if there was a change. Twenty hot springs samples were obtained from the four springs with four of those being duplicate samples. Seventeen additional samples were collected from surface waters with two of the 17 being duplicate samples. Temperature, pH, and conductivity were collected on-site at each sampling location. Sampling consisted of collecting approximately 800 milliliters (ml) of water over several bottles supplied by the laboratory. The bottles were washed using the fluid to be collected. The water was filtered if it appeared to be cloudy. The majority of the samples were not filtered due to the clear nature of the water. In addition to the water samples collected for chemical analysis, additional 25 ml samples were collected at select locations for isotope analysis. 4.1.4 Rock Sampling Geological strata, rock units, and surface layers were mapped. Outcrops were difficult to find due to the vegetation and accessible outcrops were even more difficult. Many outcrops occurred as steeply dipping walls forming river valleys and were not accessible. Geochemical alteration was minor and was not mapped due again to the vegetation (Figure 5). Where accessible outcrops were sampled and the strike and dip were obtained of features such as bedding planes, joints, and faults. 4.2 Laboratory Analysis Different laboratories were used depending upon the nature of the material submitted. Appendices A and B contain the results of the laboratory testing. For the soil samples, Skyline/Actlabs of Tucson Arizona was used. For rock analysis, Energy & Geoscience Institute will conduct petrographic analysis, fluid inclusion analysis, and analysis of the alteration minerals. The water samples were submitted to WetLab of Nevada for analysis of the cations/anions, and geothermometer components and to Southern Methodist University in Texas for isotope analysis. A selective extraction process termed enhanced enzyme leach was used at Skyline Laboratories on the soil samples. The enhanced enzyme leach process is a proprietary technique used to mainly identify mineral deposits. Trace elements become trapped within amorphous oxide coatings on sand and silt grains in soil and sediment in the near- surface environment. The extraction process leaches amorphous MnO, and analyzes 68 trace and major elements by ICP-Mass Spectrometry. The detection limits are typically on ppb levels with a few elements at the ppm level. EGI will conduct petrographic analysis of rock samples submitted. To date this has not been completed. Isotope analysis was conducted by the Stable Isotope Laboratory at Southern Methodist University. Oxygen and hydrogen isotope analysis were conducted for each sample. Every fifth sample is repeated as a standard used by the laboratory. In addition, one sample was collected at the hot springs for tritium analysis by EGI. Iterim Report — 7 HIDID res ers unnent Tenakee Inlet Reconnaissance Water samples were analyzed for the following parameters using the methodology listed. Table 4.1: Parameters tested in the water samples. PARAMETER EPA METHOD (unless noted) Total Alkalinity as CaCO3 SM 2320 B (includes Bicarbonate, Carbonate, and Hydroxide) Boron 200.7 Calcium 200.7 Chloride 300.0 Flouride 300.0 Iron 200.7 Lithium 200.7 Magnesium 200.7 Potassium 200.7 Silica 200.7 Silica (Colorimetric) Hach Sodium 200.7 Sulfate 300.0 Sulfide Hach 8131 Metals Digestion 200.2 5.0 DATA 5.1. Quality Duplicates were collected for the soil and water samples. For the shallow temperature survey, temperatures measurements were repeated at select location. In general an effort was made to resample at a rate of approximately 20 percent. Due to the scarcity and type of data obtained from the rock samples, only one sample was collected at each location. The water samples were received by WETLAB in good condition however the holding time for sulfide had expired. Silica concentrations were obtained by two different methods. The difference in these concentrations was between 0 to 5 percent for the hot spring samples but on the order of 20 to 30 percent for the surface water samples. This appears to be due to the low concentrations measured in the surface water samples. The concentrations were higher in the hot springs sample and therefore the difference in laboratory analysis was much less. Typically the colorimetric values were higher than the EPA 200.7 method. Duplicate water samples had a standard error of typically less than 10 percent for all species tested. Many of the species tested, the duplicates had a 0 percent standard error. Iterim Report - 8 HO eet Tenakee Inlet Reconnaissance SiO? (silica) for the surface water samples had a standard error of 14 and 28 percent for the two duplicate samples. Other chemical species for these duplicate samples were less than 10 percent with many being 0 percent. A duplicate analysis still needs to be conducted on the soil chemistry data. 5.2 Temperature The shallow temperature data obtained is presented in Figure 6. It can be seen that the hottest temperatures occurred near the hot springs and at the seeps found at the edge of Tenakee Creek. Temperatures near the hot spring range from 81.2 to 108.9 °F. The outflow from the hot springs had temperatures in the soil of between 58.3 and 86.1°F. Seeps were observed when the water level in Tenakee Creek was lowered during a few days of no rain. The one seep had a nearby soil temperature of 130.5 °F. Temperatures on the hillside above the spring ranged from 49.9 to 46.4 °F. A relatively cool temperature of 44.3 °F was obtained upstream of the hot springs located near the edge of the gravel bar that hosts the hot springs. Additional temperatures above background (46.5 °F) were encountered at several spots across Tenakee Creek at the base of the slope. The hottest temperature that occurred across the creek from the hot springs was 88.8 °F and another point at 59.5°F. There were several points across the creek above 50 °F with one (56.5 °F) occurring about 1,200 feet downstream of the hot springs. These temperatures do not appear to be the result of outflow from the hot springs. The temperature of the water in Tenakee Creek was approximately 40 to 45 oF, 5.3. Water The average concentrations for the hot spring water samples, the seeps water samples and the surface water samples were calculated. Table 5.1 presents the average concentrations for this group of samples. The temperature of the hot springs averaged 170 °F (76.8C) with Hot Spring #1 having the hottest temperature of 177 °F on two sampling events and Hot Spring #4 having the coldest temperatures of 161 °F and 163 °F on three sampling events. The average temperature for hot springs #1 through #3 was 172 °F. The average surface water temperature was 40°F (4.7C). The difference in between the hot springs and the surface water temperature is 130 °F. Lithium and magnesium concentrations were below the detection limit for all three sets of samples. The charge balance on each sample was typically 5 percent or less with 22 of the samples having a charge balance of 2 percent or less. The average concentrations of the species indicate that the seeps appear to be more related to the hot springs than to the surface waters. The values for the average concentrations for the seeps are closer to the hot spring averages than the surface waters.

Table 2 presents the water sample temperature and pH. Laboratory data is entered into the spreadsheet and a series of standard geothermal plots are developed. Geothermometers are calculated and ternary plots are produced. The CL-F-B plot shown in Figure 7a indicates that the hot spring waters are a separate population from the surface water samples obtained. This is important in that the two waters clearly represent separate types of fluids. The often used Cl-SO4-HCO3 ternary plot illustrates the amounts of major anions present in geothermal waters (Figure 7a). This plot indicates that the hot spring waters are low in chlorine (Cl) and bicarbonate (HCO3) and high in sulfate (SO4). This plot indicates that the hot spring waters are associated with the volcanic waters and perhaps heated by steam from a deeper reservoir. A high sulfate spring is typically associated with deeper boiling zones. The isotope plot in Figure 7b indicates that both the hot springs waters and surface waters are primarily meteoric and have not mixed with other fluids. The quartz/chalcedony solubility curve also in Figure 7b indicates based on the silica, potassium/magnesium concentrations that the chalcedony geothermometer will provide a more accurate temperature for the hot spring fluid at depth. Based on the chalcedony geothermometer the hot spring fluids have been heated to 260°F. Many of the hot spring samples have a chalcedony geothermometer of between 217 to 241°F. Iterim Report — 10 POS Tenakee Inlet Reconnaissance 5.4 Soil The soil chemistry was plotted in Figures 8a through 8f for six of the species. These chemical species had orders of magnitude changes in the concentrations of that particular species across the sampling area. Concentrations in Figures 8a through 8f were contoured using roughly the standard deviation in a particular elements concentration. The following species were plotted: Arsenic (As) Cobalt (Co) Gold (Au) Manganese (Mn) Titanium (Ti) Vanadium (V) Mercury is usually a chemical species that is measured in geothermal exploration. The mercury that occurred in the samples obtained did not indicate a large variation in concentration and therefore we did not plot this element. The species plotted indicated anomalous concentrations generally near the hot springs and along the outflow but also across the river where there were higher then background soil temperatures. The highest concentration of gold was near the confluence of the hot spring outflow and Tenakee Creek. The highest concentration for arsenic was across the river from the hot springs at the grid point that recorded the highest temperature on that side of the river. In addition, vanadium had higher concentrations along the ridge above the hot springs perhaps indicating a fracture location along this ridge. 5.5 Lineations Figure 9 presents the results of our lineation study. Lineations were determined from stereographic aerial photographs. The lineations may represent faults or joints. The lineations were not observed on the ground due to the extensive vegetation however during the helicopter flights over the area, many of the lineations could be seen on a regional scale. The lineations are typically aligned northwesterly with some cross lineations. This alignment is typical over the entire southeast region and is due to the large Queen Charlotte-Fairweather fault system and tectonics of the region. Particularly interesting is the offset in Tenakee Creek near the hot spring location. There is a set of lineations that occur northwest and the creek is offset on lineations that occur east to west. Table 3 presents the strike and dip of lineations measured in the field and taken from the geological map referenced in Figure 3. The measurements indicated steeply dipping lineations and the northwesterly strike and the cross-set. Iterim Report — ; 11 PADI arene users unnen, Tenakee Inlet Reconnaissance 6.0 PRELIMINARY INTERPRETATIONS The data presented has yet to be fully analyzed. Based on the shallow temperature probes and soil analysis there appears to be additional hot areas across the river from the hot springs. The seeps may also represent additional hot springs. The chemistry of the seeps indicates that they have some geothermal waters similar to the hot spring waters. The hot areas and the seeps along with the hot springs would suggest that the geothermal source is larger than anticipated and that there is permeability to the surface or near surface. The occurrence of chemical anomalies in the soil across the river in the hotter areas also suggests that the hot fluids are circulating near the surface bringing the chemical elements and the temperature nearer to the surface across the river. The lineations and general tectonics of the region suggest that the hot springs were developed due to the wrenching of the cross cutting lineations near the hot springs which allowed for the opening of the springs. Also given the high angle nature of many of the lineations, it is reasonable to assume that faults that bring the geothermal fluid to/near the surface are high angle. The earthquake data suggest that the area is active with crustal movement. The earthquake data and the number of lineations in the region suggest that the igneous intrusives have permeability. Based on the water chemistry, the fluids in the hot springs are most likely associated with volcanic waters and perhaps heated by steam from a deeper reservoir. This interpretation fits with the volume of igneous intrusives in the region. The chalcedony geothermometer indicates that the hot spring fluids have encountered temperatures on the order of 240 to 260°F. The surface temperatures of the hot springs are averaging 170°F. These temperatures both surface and subsurface are in the range that binary geothermal power plants operate. Much like Chena the site benefits from having cool waters at approximately 40°F as a sink. 7.0 ADDITIONAL WORK A conceptual model of the area is still to be developed. We have several models that we are working. In addition, the hydrology of the study area needs to be evaluated. Geophysical tools such as self potential will assist in evaluating the hydrology of the area and provide additional subsurface information. We currently only know about the top 60 inches of the system. We propose in the spring to conduct additional fieldwork. The following presents some of the fieldwork that still needs to be done: 1) Fly over in the spring with an infrared camera to evaluate potential other “hot” areas. During this trip collect surface water temperatures and estimate flow of Tenakee Creek — does it freeze, still flow, partially frozen during the early spring. Tenakee Inlet Reconnaissance 2) 3) 4) 5) Conduct a SP geophysical survey in order to evaluate the hydrology of the area and provide additional subsurface information. Conduct additional study of the area across the river from the hot springs where there are high temperature probe data and anomalous soil data. Investigate further the seeps near the edge of the creek to determine if they are seeps from the hot springs or additional springs. Excavate holes to groundwater along the gravel bar to evaluate flow from the hot springs to the seeps. Collect flow data from the hot springs, creek, and outflow areas. How to collect the hot springs flow will have to be developed since it was awkward with a conventional flow meter to obtain during the first field study. 8.0 CLOSURE AND LIMITATIONS The analyses and conclusions included in this report are based on conditions as they exist in the literature and gathered data. This report is an interim data report. Conditions and conclusions may change as additional data is obtained. Use of this report should be limited to its purpose as a reconnaissance effort.

Sincerely, Anke Andy Smith QA Manager Page | of 13 Western Environmental Testing Laboratory Report Comments Hattenburg Dilley & Linnell - 1110060 General Comments The samples were received by WETLAB-Western Environmental Testing Laboratory on 10/5/2011. By this time, the EPA recommended holding time for Sulfide had expired. The analysis was performed on all submitted samples upon receipt past the holding time per client’s request. Specific Comments None Data Qualifier Legend B - Blank contamination; Analyte detected above the method reporting limit in an associated blank HT = - Sample held beyond the accepted holding time J -- The reported value is between the laboratory method detection limit and the laboratory practical quantitation limit M — Reported value is estimated; The sample matrix interfered with the analysis N — There was insufficient sample available to perform a spike and/or duplicate on this analytical batch. NC — Not calculated due to matrix interference Q =~ Reported value is estimated; The value failed to meet QC criteria for either precision or accuracy SC = Spike recovery not calculated. Sample concentration >4X the spike amount; therefore, the spike could not be adequately recovered.

Sincerely, Andy Smith QA Manager Page | of 20 Western Environmental Testing Laboratory Report Comments Hattenburg Dilley & Linnell - 1110199 General Comments The samples were received by WETLAB-Western Environmental Testing Laboratory on 10/13/2011. By this time, the EPA recommended holding time for Sulfide had expired. The analysis was performed on all submitted samples upon receipt past the holding time per client’s request. Specific Comments Due to the sample matrix it was necessary to analyze the following at a dilution: 1110199-008,010,015,016,018,020 Iron The reporting limits have been adjusted accordingly. Data Qualifier Legend B — Biank contamination; Analyte detected above the method reporting limit in an associated blank HT = Sample held beyond the accepted holding time J -- The reported value is between the laboratory method detection limit and the laboratory practical quantitation limit M -~ Reported value is estimated; The sample matrix interfered with the analysis N — There was insufficient sample available to perform a spike and/or duplicate on this analytical batch.
