The Little Tonzona River coal field is located approximately 150 air miles northwest of Anchorage, Alaska, and 210 air miles southwest of Fairbanks, Alaska; near the boundaries of Denali National Park. The Alaska Railroad and the Parks Highway are approximately 100 air miles from the coal field at their nearest point. The village of McGrath, on the Kuskokwim River, is located approximately 90 miles to the west (1). An impressive outcrop of coal-bearing Tertiary sediments is exposed for a distance of more than 275 feet on the west bank of the Little Tonzona River (Figure 1). More than seven coal beds, ranging in thickness from 3 feet to 30 feet, with a cumulative thickness of over 134 feet, are interbedded with clay beds up to 40 feet thick. The clays are fine textured, extremely plastic, light grey to nearly white bentonites and/or tonsteins. Doyon Ltd., an ANSCA Native Corporation, holds land selections covering the inferred limits of the coal field. During 1980 and 1981, Doyon entered into exploration agreements with McIntyre Mines Inc. of Nevada. The two season exploration program took place from June 1, 1980 through August 22, 1980 and from May 27, 1981 through August 22, 1981. During the 1980 field season, geologic mapping, prospecting, stratigraphy, trenching and bulk sampling of all coal outcrops were performed. This produced a total of 34 samples, which were taken for analysis. In 1981, six diamond drill holes with a cumulative length of 2,935 feet were completed. Core recovery was close to 90%, and a total of 147 coal samples, which represented 802.8 cumulative feet of coal, were taken for analysis. The exploration program confirmed a strike length of over 3 miles to the southwest from the main river bank exposure. Northward extension is unknown at this time. Although outcrop exposure is poor away from the river banks, burnout zones resulting from past coal bed fires form a resistant, recognizable on strike feature in the relatively unindurated Tertiary sequence. The appearance of these burnout zones along strike is often the only surface indication of the buried coal-bearing strata. Well preserved plant fossil impressions in the baked clays date the deposit as probable Miocene (2). Coal characterization and washability studies were performed on all coal samples by the Mineral Industry Research Laboratory of the University of Alaska Fairbanks. This work was conducted under the direction of Dr. P.D. Rao, Professor of Coal Technology. (b) Figure 1: Coal outcrop on the west bank of the Little Tonzona River. Aerial view (a) and from ground level (b). In the river bank exposure, the coal rank tends to decline up-section, to the northwest, as the coal beds become younger. The younger beds are thinner and more lignitic. Analyses averages for the 147 samples taken in 1981 are shown in Table I. Table I.

Although the sulfur content of Little Tonzona coal is high for an Alaskan Tertiary coal, it is similar in other ways to other coals of the same age and rank from within the state (Table II).

Each one trillion tons of subbituminous coal contains the energy equivalent of approximately 5,500 years of Alyeska Pipeline production (@ 1.5 MM barrels/day). The locations of the major coal regions in Alaska are shown in Figure 2. The largest of Alaska's coal basins, estimated to be over 4 trillion tons, is the Northern Alaska Basin. It consists of a tremendous subbituminous coal deposit, which in areas overlies a rich bituminous deposit (4). The Cook Inlet-Susitna Basin, which is composed mainly of low-rank coals, may contain over a trillion tons (4). The remainder of the coal basins are small by Alaskan standards but still contain billions of tons of reserves. As an examples, the Nenana Basin, which boasts Alaska's only operating mine, the Usibelli Coal Mine, has "only" about 10 billion tons of proven reserves (4). The outstanding feature of almost all Alaskan coals, regardless of rank, is their extremely low sulfur content (5). The majority of the Alaskan coals are already compliance coals. Many of the low-rank coals have sulfur levels below 0.2%. The latest three year average for the Usibelli subbituminous coal was 0.17%. In addition, many of the low rank coals (LRCs) have moderate ash levels and reactivities typically an order of magnitude higher than their bituminous counterparts. Major reasons for the limited use of Alaskan coals include low population density, distance from high energy use areas, abundant more convenient energy forms (gas and oil) and mining and transportation costs. In addition, the low sulfur, highly reactive LRCs are plagued with the high moisture inherent to their rank. This has restricted the worldwide usage of most LRCs to mine mouth power generation. However, new technologies could expand international use of LRCs and provide a valuable Alaskan export to nations of the Pacific Rim. The majority of this report consists of the characterization data for the 147 Little Tonzona coal samples taken from diamond drilling during the 1981 exploration program. A brief description of the Little Tonzona coal deposit geology in the next section is followed by the detailed protocol for coal characterization procedures. Geology Coal bearing rocks of the Farewell area were first mentioned in the literature in 1911, by Alfred H. Brooks of the U.S. Geological Survey, who traversed the areas in 1902 (6). The impressive coal exposure on the west bank of the Little Tonzona River (Figure 3) was first examined closely by Gary Player, a consulting geologist from Anchorage, Alaska, in August of 1970 (7). In August 1976, the outcrop area was revisited and sampled NORTHERN LISBURNE FIELD Hee k i ¢ ii 7 ALASKA COAL 926 million s.t. or igh rank coal ow rank coa FIELDS as! 8.t.cshort tons 4 trillion s.t.

Hawley and Associates, Inc., contractor to the U.S. Bureau of Mines, during a study of mineral resources of Federal D-2 lands being considered for inclusion in Denali National Park (7). In August of 1977, the U.S. Geological Survey performed a reconnaissance survey for coal in the Minchumina Basin and Farewell vicinity. The Little Tonzona coal outcrop was again visited and sampled (8). During the same summer, the deposit was examined by WGM Exploration, Inc., as part of a Doyon Ltd. project. A coal sample was collected 2.3 miles southwest along strike from the main river outcrop (9). The Little Tonzona coal basin has a strike length of over 3 miles, from the river bank exposure, to the southwest (Figure 4). The coal beds range from 3 to 30 feet in thickness and are interbedded with clay seams. Dips as steep as 75° may be found, but the general range is between 45° and 70° NW. Up to 8 feet of glacial gravel deposits and a thin soil unconformably overlie the main coal exposure. Permafrost is present in the area but is discontinuous, depending upon the slope exposure (1,2). The coal bearing units are truncated on the southern end by a NE - SW trending strand of the Farewell Fault, the major structural influence of the area. Although the coal and clay beds in contact with the fault trace are crushed and deformed, up-section to the north, away from the fault, the coal is nearly undisturbed, except for the steep dips. The fault trace apparently separates Tertiary sediments on the north side from Paleozoic limestones on the south side. Fault movement appears to have been south-side-up dip slip with a right-lateral component. This movement is the apparent cause of the severe dips where Tertiary strata abut the fault trace. These steep surface dips apparently flatten to the north at fairly shallow depth, according to drilling indications (1,2,11). Laboratory Procedures Coal characterization and washability tests were performed on all of the drill core samples submitted to MIRL in 1981. Characterization included proximate and ultimate analyses, Hardgrove grindability index tests, analyses of major oxides in the coal ash and ash fusibility measurements. Washability analyses were performed using representative splits of 3/4-inch x 100-mesh (0.15 mm) coal at 1.30, 1.40 and 1.60 specific gravities. All analyses were performed according to ASTM standards and procedures. Coal samples were received at the laboratory in tightly sealed plastic containers and some samples showed visible surface moisture on the coal. Sample weights ranged from 4.5-30 pounds.

(1,2,10) Figure 5 is a flowsheet of procedures used in the laboratory for processing the samples. The cores were first crushed in a jaw crusher to produce a minus 3/4 inch product, then riffled. Half the sample was screened at 100 mesh, and the 3/4 inch x 100 mesh fractions were used for washability studies. The other half of the sample was further crushed to minus 3/8 inch in a jaw crusher. 500 g samples were split out of the -3/8 inch coal and air dried for Hardgrove grindability index (HGI) tests. Moisture content was determined for the samples used for HGI determination. 5 pound samples were split out of the -3/8 inch coal for raw coal analyses, then crushed to minus 14 mesh (1.41 mm). From the minus 14 mesh coal, samples were split for equilibrium moisture determination and 500 g samples were split for air dry loss determination and further pulverization to 60 mesh (0.25 mm). The pulverized coals were used for proximate and ultimate analyses. Coal samples combusted at 750°C yielded ashes, which were used for ash fusibility measurements and for determination of major oxides in the ash by x-ray fluorescence spectrometry. Float-sink separations were made in 15 gallon containers at 1.30, 1.40 and 1.60 specific gravities using perchlorethylene - naptha mixtures as heavy liquid. The float- sink products were air dried, weighed, crushed, and pulverized. They were analysed for moistures, ash, heating value, total sulfur and pyritic sulfur. All weights and analyses were calculated on a moisture free basis. Tables 2 through 7 show proximate and ultimate analyses of raw coals for the six drill holes. The analyses are presented on 1) equilibrium bed moisture basis, 2) as received basis, 3) moisture free basis and 4) moisture and ash free basis. Most samples had higher as received moisture than equilibrium moisture. The difference was the extraneous surface moisture introduced during drilling. Coal, as mined, would be expected to have moisture levels comparable to equilibrium moisture. HGI values are presented in Tables 8 through 13. The distribution of major oxides in the coal ashes are shown in Tables 14-19 and the ash fusion temperatures are presented in Table 20 through 25. HGI averages within drill holes ranged from 30 to 38 with an overall average for all 147 samples of 35. These values indicate that raw coal from the Little Tonzona field would be relatively hard to grind or pulverize. The low sodium content of Little Tonzona coal ash indicates its low boiler fouling propensity. Likewise, the high calcium levels would also reduce the boiler fowling propensity of sulfur. The high calcium content would likely fix much of the sulfur in the ash and reduce sulfur emissions. Calculations using emperical formulas show that the ash will have intermediate slagging characteristics. This was also verified from the ash fusibility data.

The tables show weight percent distribution, ash, heating value, pyritic sulfur, and total sulfur on a moisture free basis for the various gravimetric fractions as well as values for cumulated floats. The quality of the floats at any of the three densities can be read directly from the tables. The tables also show cumulative sink weight percent and ash content that may be expected at any of the three densities. Finally, Tables 32 and 33 present petrologic data for certain samples from the drilling program. Table 32 gives ulminite reflectance rank distribution data and Table 33 presents coal maceral distribution for samples from drill hole no. 1. Each set of tables is preceded by a table(s) overview, which presents a summary of data contained within a group of tables. This should facilitate the reader's rapid comprehension of tabulated data. 11 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) References Cited Thorpe, W.H., 1981, Tonzona Project Summary Report for 1980.

They present proximate and ultimate analyses of the raw coals from the six drill holes. The analyses are presented on 1) equilibrium bed moisture basis, 2) as received basis, 3) moisture free basis and 4) moisture and ash free basis. Most samples had higher as received moisture than equilibrium moisture. The difference was the extraneous surface moisture introduced during drilling. Coal, as mined, would be expected to have moisture levels comparable to equilibrium moisture. Proximate analyses averages, from Tables 2-7, are shown in Table I, page 3, which is reproduced below for the readers convenience. Table I shows a broad range of analytical values. This is due in part to the variation in the nature and percent ash in the coal samples taken from the drilling program. Coal rank tends to decline up-section, to the northwest, as the coal beds become younger. The younger beds are thinner and more lignitic. Table I.

The 147 coal samples had an average heating value of 6,707 Btu/lb and averages of 31.73% moisture, 32.40% volatile matter, 25.71% fixed carbon, 10.31% ash and 1.04% total sulfur on an equilibrium bed moisture basis. Although the sulfur content of Little Tonzona coal is high for an Alaskan tertiary coal, it is similar in other ways to other coals of the same age and rank from within the state.

Hardgrove grindability index (HGI) data from Tables 8-13, are consistent with coal of subbituminous rank. Despite the range of HGI values observed, 23 to 71, approximately 90% of the values lie within an HGI range of 25-47. HGI averages within drill holes ranged from 30 to 38 with an overall average for all 147 samples of 35. These values indicate that raw coal from the Little Tonzona field would be relatively hard to grind i.e., require larger amounts of energy for pulverization. 45 Table 8.

Tables 14-19 show the chemical composition of ash of the coal samples. Ash is the product of heating the inorganic constituents during coal combustion. Ash is prepared by heating coal to 750°C in a well ventilated furnace. The resulting residue is analyzed for eight major elements and three minor elements expressed as oxides . The major oxides are Si02, AlgO3, Feg03, MgO, CaO, NagO, Ko0, and SO3. Minor oxides are Ti02, MnO and P9205. The relationship of ash composition to its behavior during coal combustion operations has been correlated. Emperical equations are available to successfully predict ash behavior from its composition. The low sodium content of Little Tonzona coals indicates their low boiler fouling propensity. The high calcium content would likely fix much of the sulfur in the ash and reduce sulfur emissions. High calcium levels would also reduce the boiler fowling propensity of the ash due to the coal's sulfur content. Calculations using emperical formulas show that the ash will have intermediate slagging characteristics. This can also be seen from the ash fusibility data (Tables 20-25). 51 es Sample Number 41676 41677 41678 41679 41680 41681 41682 41683 41684 41685 41686 41687 41688 41689 41690 41691 41692 41693 41694 41695 41696 41697 41698 41699 41700 Si02 44.5 54.3 28.9 54.7 49.7 18.4 35.0 45.5 40.3 55.9 32.3 34.3 35.3 26.6 24.1 28.8 26.3 34.2 38.8 18.3 34.1 24.3 39.8 39.8 52.1 A1203 18.0 26.1 20.7 29.3 19.7 16.9 23.2 26.7 27.7 23.2 24.8 24.3 17.0 20.1 13.4 22.4 20.1 17.7 21.8 17.0 22.7 16.6 23.8 18.7 12.5 Table 14.

Fusibility of ash was determined by subjecting cones prepared with coal ash to increasing temperatures. Temperatures at which transformations occur in the cones are recorded. The temperature at which rounding of cones occur is reported as initial deformation temperature. As the ash cone is heated to higher temperatures it softens further and the temperature at which the cone height is equal to the cone base length is termed softening temperature. When the ash cone completely melts and spreads over the base, the fluid temperature is recorded. Coals with softening temperature below 2000°F are termed slagging coals. Coals with ash softening temperatures above 2600°F are termed non slagging. All of the Little Tonzona samples tested had ash softening temperatures between 2200 and 2600°F and thus may or may not form slag depending on combustion process conditions. Combustion equipment could be designed to prevent ash from melting in cases where coal was burned in a stoker furnace. Alternatively, provisions could be made to melt the ash and keep it flowing, removing it as slag from cyclone type furnaces. 60 Table 20.

They show washability data for all samples from the six drill holes. The tables show weight percent distribution, ash, heating value, pyritic sulfur, and total sulfur on a moisture free basis for the various gravimetric fractions as well as values for cumulated floats. The quality of the floats at any of the three densities can be read directly from the tables. The tables also show cumulative sink weight percent and ash content that may be expected at any of the three densities. Reduction of sulfur due to washing was small, even for samples in which pyritic sulfur exceeded 0.5%. The pyrite in Little Tonzona coal is apparently still locked for the coal size range (3/4" x 100 mesh) tested. Good coal recoveries can be expected by washing the coal to 8 to 10% ash.

They present petrologic data for samples from drill hole no. 1. Table 32 gives ulminite reflectance rank distribution data and Table 33 presents coal maceral distribution for the coal samples. Reflectance of ulminite is an indication of the rank of coal. The mean value of 0.22 percent indicates that the Little Tonzona coal ranks in the subbituminous 'C’ and lignite range. The narrow (three or less) reflectance class distribution for ulminite is indicative that this seam was not thermally influenced by any intrusive activity. Maceral analysis of the samples is shown in Table 33. Various macerals are indicative of their source material and environment of deposition. The macerals ulminite, gelinite, phlobaphinite and pseudo phlobaphinite originate from woody portions of plants and are highly reactive. The liptinite macerals are waxy substances from various parts of plants; sporinite (spores), resinite (resins), alginite (algal remains), exudatinite (forming resin) cutinite (leaf cuticles), and suberinite (a wax coating of root tissues). Liptinite macerals yield a higher percentage of gas during gasification. The inertinite macerals fusinite, semifusinite and macrinite form from woody portions of the plant. These macerals are partly inert to liquefaction and burn with less ease than other macerals. The Little Tonzona coal samples generally contain over 90% reactive macerals. This is in line with other Alaskan subbituminous coals. 118 Table 32.
