Applied Minerals, Inc. (“Applied Minerals”) (OTCBB: AMNL), a leading global producer of Halloysite Clay, is pleased to provide an update of the Dragon Mine.

Progress report including Resource Statement - Dragon Mine, Eureka, Utah, USA

April 2011 - Prepared by Dr. Ian Wilson, consulting independent Geologist to Applied Minerals, Inc.

Background to Applied Minerals

Applied Minerals, Inc is a US publicly traded SEC reporting company with $60 million Current Enterprise Value. Applied Minerals owns the Dragon Mine Halloysite deposit in Utah and sells under the Dragonite™ tradename. New management took over from Atlas Mining Company in January 2009 and implemented a new Board of Directors and appointed geological and technical consultants for advice. With strong financial backing, Applied Minerals is nearing completion of a three-year study into the resources and markets to be served from the Dragon mine operation.

The Dragon Mine is located in Tintic District of north central Utah, some 75 miles southwest of Salt Lake City. The area covers 230 acres and includes 38 patented claims. Currently there are two underground portals with workings. Five waste piles left by Filtrol from surface and underground mining are present on the property. Applied Minerals has recently been granted a permit to mine throughout the year. There is currently an onsite dry milling and jet milling operation producing some products with capacity dependent on the grade of halloysite.

The property has a long history of mining from initial iron ore mining, where some gold was extracted from the smelting of the ore, through to mining of halloysite. Mining stopped in 1971 and over the last decade attempts have been made to re-commence production of halloysite. Filtrol Corporation mined over one million tons of halloysite from the surface and underground from 1949-1976 for use as a petroleum cracking catalyst. Since May 2008 a detailed investigation has been conducted of all available data with further drilling being carried out to determine remaining resources of halloysite.

Geological setting

Geologically the property is varied, with Palaeozoic limestone being intruded by the Tertiary igneous Silver City monzonite porphyry and iron ore. The mineralisation is fault controlled and the clay mineralogy is often dependent on the host rock. In the pit area, where there is a large body of iron ore, the clay is dominantly halloysite (100% in places) with the potash feldspar in monzonite being altered to halloysite, kaolinite and illite-smectite. The iron ore is a mixture of goethite, hematite and an amorphous iron phase identified as ferrihydrite (this is a new occurrence identified in the current investigation). The property is located along an extension of the Silver City Quartz Monzonite stockwork and there is interest in whether there is a hidden copper porphyry deposit present at depth. The current exploration for halloysite is ongoing and this statement gives an update of work carried out over the last three years leading to the current commencement of production. Detailed research has been carried out recently by Applied Minerals for new uses of halloysite in plastics, as a flame retardant and in other applications with two new patent applications pending. The Dragon property represents one of the largest known deposits of halloysite in the world, and along with the presence of other clay minerals and iron ore, has the potential to enter a wide range of markets.

  • Testing of cores from 80 boreholes drilled in 2003, 2005, 2006, 2009 and 2010 totalling 15,362 ft. Average depth of 80 boreholes drilled is 192 ft and range of depths drilled from 50 to 360 ft.
  • The Western area drilled from 2003 to 2006 includes 44 boreholes totalling 9,448 ft and covers an area of 6.33 acres. This was drilled in mainly altered quartz monzonite, which is an intrusive igneous rock with approximately equal parts of orthoclase and plagioclase feldspar. Quartz monzonite porphyry is often associated with copper mineralisation in porphyry copper deposits.
  • The Dragon Pit area drilled in 2009-2010 includes 36 boreholes totalling 5,914 ft and covers an area of 4.95 acres. The area is mainly iron ore and some altered monzanite on the periphery of the area. High levels of halloysite up to 100% are adjacent to the iron ore.
  • To date over 500 samples of borehole material has been tested to determine their mineralogy, particularly for halloysite, kaolinite, illite-smectite levels and other properties.
  • Drilling of five waste piles from previous clay mining activity. Waste piles cover 34.2 acres and have a volume of 1.99 million cubic yards. Following a detailed trenching campaign on the waste piles, fifty-two boreholes were drilled totalling 1,986 ft. The whole rock evaluation included chemical testing by XRF of all 216 samples generated with 69 for their mineralogy by XRD. To determine clay content, samples were processed to <45 µm and <5µm fractions and 185 samples were tested for their mineralogy by XRD and 133 samples for their chemistry by XRF.
  • Evaluation of the iron ore present in the Pit Area (4.95 acres) and elsewhere. Testing of almost 100 samples to determine quality.
  • Detailed evaluation of surface samples from which some halloysite is now being mined from the open pit.

    • Clay resources within the Dragon Pit area
    • Clay resources within the Western Area
    • Whole rock evaluation of five waste piles
    • Evaluation of clay fraction of five waste piles
    • Iron ore resources within the Dragon Pit Area
    • Iron ore resources within the Western Area

Evaluation based on testing of cores from 80 boreholes drilled in 2003, 2005, 2006, 2009 and 2010 totalling 15,362 ft and covering an area of 11.28 acres. Average depth of 80 boreholes drilled is 192 ft and range of depths drilled from 50 to 360 ft.
  • Dragon Pit area - 4.95 acres

Measured Resource based on drilling in 2009-2010 includes 36 boreholes totalling 5,914 ft of core. The area is mainly iron ore and some altered monzonite on the periphery of the area. High levels of halloysite up to 100% are adjacent to the iron ore and probably formed from solution. There is no alunite present in this area and the halloysite varies in colour from white to light brown, the latter due to the presence of goethite.

Measured Resource of 552,000 tons of halloysitic clay from the Dragon Pit area:

          Area   Acres   Resource   Clay   Av Thickness   % Average Clay Content
        Status   Tonnage   (feet)   Halloysite   Kaolinite   Illite-Smectite   Total
Dragon Pit   4.95   Measured   552,500   40   64.8   18   10.6   93.4
  • Western Area - 6.33 acres.

The Western area drilled from 2003 to 2006 includes 44 boreholes totalling 9,448ft and covers an area of 6.33 acres. Of 216 samples collected, 185 were tested for their mineralogy (XRD) and 131 for their chemistry (XRF). This area is dominantly altered Monzonite with some veins and fissures of whitish clay with kaolinite, halloysite and alunite. One area covering 0.8 acres shows an average value of 25.6% halloysite. Within the altered monzonite visible pyrite is observed.

From 6.33 acres an area of 0.8 acres has a Measured Resource of 44,200 tons with remaining 5.53 acres an Indicated Resource of 776,500 tons of clay:

          Area   Acres   Resource   Clay   Av Thickness   % Average Clay Content
        Status   Tonnage   (feet)   Halloysite   Kaolinite   Illite-Smectite   Total
Western   0.8   Measured   44,200   31   25.6   36.8   6.4   68.8
Western   5.53   Indicated   776,500   111   4.1   47.4   24.4   75.9

Drilling of five waste piles from previous mining activity was carried out covering an area of 34.17 acres. The five waste piles have a volume of 1.99 million cubic yards. Following a detailed trenching campaign on the waste piles, fifty-two boreholes were drilled totalling 1,986 ft and 216 samples were tested.
  • Whole rock evaluation of five waste piles - 34.17 acres

The whole rock evaluation included chemical testing by XRF of all 216 samples with 69 tested for their mineralogy by XRD. The tonnage of 4.5 million tons is based on specific gravity of 2.5. The waste piles show variation in their chemistry and mineralogy and reflect where they were mined from. WP1 is high in halloysite and iron and was mined from the iron rich zone where halloysite levels tend to be higher. The other waste piles are clearly mined from mainly monzonite where the alteration of feldspar has been more to kaolinite and illite-smectite rather than halloysite. The levels of K-feldspar and quartz are also higher for the waste derived from altered monzonite.

Potential markets are being evaluated for the waste piles. It is believed that the material, upon crushing to a fine particle size, will have certain applications as an agricultural carrier, soil nutrient and sorbent for environmental remediation. The presence of ferrihydrite mixed with clays will have some use in remediation of contaminated sites, especially when mixed with halloysite, kaolinite and illite-smectite.

It is considered that the 4.5 million tons of waste pile material has an Inferred Resource status. Work is ongoing looking at potential markets.

  • Evaluation of clay fraction of five waste piles

For this study 185 samples were tested for their mineralogy by XRD and 133 samples for their chemistry by XRF. Clay was refined to <5 microns for all waste piles apart from WP3, which was processed to <45 microns. 500 tons of WP1 was wet processed at KaMin’s plant in Sandersville and some of this is being trialled by a potential customer at the present time with encouraging results. Given this encouragement WP1 is considered a Measured Resource with remaining waste piles an Indicated Resource status. There is a total of 757,880 tons of clay that can be processed from the five waste piles.

Measured Resource of 154,500 tons from Waste Pile 1 which is high in halloysite. Indicated Resource of 603,380 tons from Waste Piles 2, 3, 4 and 5

Of thirty-six boreholes (5,914 ft drilled in 4.95 acres in the Dragon Pit area) thirty-two contained iron ore. Iron ore was encountered to below the 500 ft level and could well go farther on basis of iron being reported at 1000 ft adjacent to the old shaft. XRF was carried out on 87 core samples (and further samples from outside of pit area). The mineralogy is a mix of goethite, hematite and amorphous iron (identified as ferrihydrite). Some zones are high in goethite, which is a light to dark yellowish ochre, which will have applications as a pigment. A Measured Resource of iron ore in the pit area of 2,104,000 tons has been calculated.

Average Quality of Iron Ore from Pit area (4.95 acres) is as follows:

          Iron Ore Composition (Wt %)
Fe 52
Si 3.12
Al 1.69
Ca 0.31
Mg 0.09
Mn 0.59
P 0.3
S 0.29
LOI 12

From the Western area (6.33 acres) iron ore was logged in the boreholes and an Inferred Resource of 688,300 tons is identified. Eight samples were collected and show presence of hematite, goethite and amorphous iron (ferrihydrite). Because of the small size of individual crystals ferrihydrite has a large surface area of several hundred square meters per gram. In addition to having a high surface area to volume ratio, ferrihydrite has the ability to adsorb arsenic, lead, phosphate, and organic molecules. Its strong and extensive interaction with trace elements is used in water purification plants to clean wastewater and groundwater. An example of this is to remove arsenic from industrial effluents and drinking water.

Goethite (ochre) is being studied from the mine as a pigment and some trials have been carried out

Market Statistics of Iron Oxide Pigments for 2010 (U.S. Geological Survey, Mineral Commodity Summaries, January 2011) prepared by Arnold O. Tanner


(Data in metric tonnes unless otherwise noted)

Domestic Production and Use: Iron oxide pigments (IOPs) are mined by three companies in three states in the United States. Production data, which were withheld by the U.S. Geological Survey to protect company proprietary data, increased slightly in 2010. There were seven companies, including the three producers of natural IOPs that processed and sold finished natural and synthetic IOPs. Sales by those companies increased 15% to 20% in 2010, although sales were still below the sales of 88,100 tons in 2007. About 50% of U.S. consumption was for colorizing construction materials such as concrete. Another 30% was used in coatings and paints, 18% in plastics and rubber, and 2% for unknown uses.

Apparent US consumption of natural iron oxide pigments was 200k tons in 2010, down from 261k tons in 2007. Greater than 50% of the US demand was exported from foreign countries, predominantly Cyprus, Spain and France.with China being the major supplier of synthetic material.

The average pricing for the consumed pigments in 2010 averaged $1.54/kg or $1,540.00/tonne, up from $1.38/kg or $1,380.00/tonne.

Further work is planned on testing some of the borehole material and drilling deeper below the 500 ft level. There is potentially at least a further 500 ft of iron ore to drill through to 1,000 ft level and perhaps goes even deeper which needs to be proved by drilling.

Iron ore resources identified to date:

Measured Resource of Iron Ore in Pit Area (4.95 acres)

2,104,000 tons

Inferred Resource of Iron Ore in Western Area (6.33 acres)

688,300 tons

Total Measured and Inferred Resources of Iron Ore


2,792,300 tons

The iron ore, from previous mining records, is present at the 1,000 ft level adjacent to the old shaft. Unfortunately access underground has not been possible since a fire in 1971. The current re-opening of the mine to the 300 ft level has just been achieved and evaluation of the ground conditions underground is being carried out with further exploration drilling planned both laterally and in depth.


A number of laboratories have been commissioned to carry out the detailed study made at Dragon Mine. The first important step was to establish an XRD (X-Ray Diffraction) technique to give accurate percentages of all mineral phases present. This work was carried out by Dr Stephen Hillier of the Macaulay Institute in Scotland along with Dr. Ian Phillips, Evelyne Delbos, Helen Pendlowski and others utilising not only XRD but XRF, ICP-MS, Scanning Electron Microscopy, Infra-Red analysis, porosity, surface area, particle size distribution and brightness/colour measurements. Exploration activity was planned by Ian Wilson, who logged all boreholes and arranged sampling by the Dragon Mine staff under the leadership of Jim Enyeart, Mine Manager. Rick Lyman, Lyman Exploration & Surveying Outfit of Clinton, Utah, has carried out all surveying in the area. Geological data and results are entered into PCCORES system by George Swindle of Mentor Consultants, Chicago for resource evaluation.

Detailed evaluation of boreholes was mainly carried out in UK by Goonvean Ltd, a leading kaolin producer under the direction of Frank Hart, Technical Manager and Robert Canning (now retired and a Consultant). Other evaluation work of boreholes and some processing trials on various bulk samples was carried out by Grinding Solutions in Truro, UK by Nick Wilshaw (Managing Director). Over the last year or so KaMin Performance Minerals LLC, a leading kaolin producer in Georgia, USA has carried out processing trials and prepared detailed results and reports on their findings. XRF analysis on iron ore samples was organised through Tom Needs, Director, USA Operations and carried out by ALS Minerals Division.


Precious Metals and other metals potential

In the late 1870s, mining at the Dragon concentrated on the iron ore present within and lateral to the Dragon vein system. The iron ore was in demand for use as a fluxing agent for lead smelting. A study carried out by Centurion Mines demonstrated there was great interest in gold present in the iron ore. Pre-1900 production data from the Dragon shows approximately 315,000 tons of gold-bearing iron was mined with values of gold from 0.1 to 0.3 ounce to the ton. U.S. Bureau of Mines Metral Production Records show that between 1904 and 1920 the Dragon Mine was credited with 18,000 ounces of gold and 928,000 ounces of siliver from around 305,000 tons of iron ore shipped - the figures for gold and silver being based on credits paid by the smelter.

The Dragon Mine is present at the contact between the Silver City quartz monzonite stock and limestone and dolomite of the Paleozoic formation. Gold and siliver is found in veinlets in pervasively altered rocks of the Silver City stock immediately south of the Dragon mine and were one of the first discoveries made in the Tintic district in 1869. The Dragon was mined as a copper-gold deposit not long after these initial findings. The Dragon fissure fault system forms the southern extremity of the Iron Blossom ore run.

Exploration is being carried out by a major company within 5km of the Dragon Mine in order to determine the possibility of a large, buried porphyry copper-gold deposit. Testing of surface rock samples in the vicinity of the Dragon Mine carried out in the past show anomalous copper values with gold values over one ounce per ton and siliver values of around five ounces per ton. It is believed that there is enough geological evidence to justify two to three deep boreholes to determine the presence of mineralisation at depth.


Further drilling and evaluation is planned in other parts of the property where indications are that further halloysite, other clay minerals and iron ore are available. To date, only shallow drilling has been carried out. Now that access to the 300 ft level has been achieved, some underground drilling will be carried out to greater depths to further evaluate the halloysitic clay and iron ore. A further update on Resources will be issued when this work is complete. It is envisaged that two to three deep boreholes will be drilled to determine the presence of mineralisation at depth.

  • Target markets are wide and varied and include polymer composites, flame-retardants, paint & coatings, adhesives, catalysts, environmental remediation and extended release carriers. Two patents for new products have been filed.
  • Iron ore as a pigment based on the goethite (ochre). Ferrihydrite is a fine particle size iron ore used in water treatment.
  • Applied Minerals has announced cooperation with various companies and to date samples for commercial evaluation have been sent to over 100 interested parties.
