The Beatrice mine is situated near the timber line at 2103 metres elevation, at the head of the southeast fork of Mohawk Creek. The property consists of six contiguous claims including the Beatrice (Lot 4586) and Folsom (Lot 4587).

The area is underlain by a northwest-southeast–trending belt of metasedimentary rocks of the Cambrian to Devonian Broadview Formation (Lardeau Group). This is on the same belt of rocks as the Silver Cup (MINFILE 082KNW027), Nettie L (MINFILE 082KNW100) and True Fissure (MINFILE 082KNW030) mines of the Ferguson camp to the southeast. Black slates, carbonaceous schists, grey and reddish-brown weathering grits and quartzites and greenish-grey talcose schists underlie the property. On average the rocks strike 140 degrees and dip 65 degrees northeast.

The mine workings develop two principal vein-lodes: the Beatrice and the Main veins, which are hosted by quartz-rich grits, carbonaceous phyllites and graphitic schists. The Beatrice vein, which was the original discovery at surface, strikes 050 degrees and dips 65 degrees southeast across the axis of the controlling synclinal structure. The Main vein, found only on the lower levels of the mine, strikes 140 degrees and dips 65 degrees northeast. Ore occurs as irregular veins in shear zones, on bedding plane slips and in crosscutting faults. The veins range in width from a few centimetres to a few metres and consist of sphalerite, galena, tetrahedrite, pyrite and trace chalcopyrite in quartz gangue with minor calcite. Replacement is considered to be an important factor in the formation of the ore.

The No. 1 adit was crosscut to the Beatrice vein, where considerable stoping was done. Above the level the vein was mined for a vertical distance of approximately 18 metres and horizontally for 20 metres. The ore appears to have been hand cobbed in the stope and backfilled with rejected subgrade debris. The mineralization consists of a solid band of pinching and swelling massive sulphides, ranging up to 50 centimetres wide. The hangingwall is a 2-metre-wide siliceous zone carrying disseminated sulphides.

In 1914, sampling is reported to have yielded 8.5 grams per tonne gold, 4129 grams per tonne silver, 17.42 per cent lead and 10 to 23 per cent zinc (Annual Report 1914, page 267).

In 1964, a sample (80327) from the hangingwall of the glory hole zone (Beatrice vein) assayed 1.4 gram per tonne gold, 458.3 grams per tonne silver, 2.56 per cent lead and 14.99 per cent zinc over 3.6 metres (Property File - Dakota Silver Mines Ltd. [1964-09-08]: Report on the Beatrice Property).

In 1977, a sample from the face of the No.1 adit assayed 0.7 gram per tonne gold, 485.6 grams per tonne silver, 3.08 per cent lead and 12.18 per cent zinc over 0.84 metre (Property File - R.C. Hart [1982-12-01]: An Analysis of Reports on the Beatrice Property).

In 1986, sampling the Beatrice vein from a drift face in the No.1 level yielded up to 0.5 gram per tonne gold, 453.1 grams per tonne silver, 3.13 per cent lead and 10.19 per cent zinc over 0.75 metre, whereas sampling of the hangingwall of the glory hole zone yielded 453.1 grams per tonne silver, 2.38 per cent lead and 12.88 per cent zinc over 2.7 metres (Property File - Dunhill Resources Corp. [1988-01-22]: Geological Report on the Beatrice Property).

In 2017, a composite grab sample (1752204) from a large open cut located above the Beatrice upper adit assayed 0.24 per cent lead, 3.53 per cent zinc, 152 grams per tonne silver and 1.45 grams per tonne gold, while a select grab sample (1752214) from the Beatrice upper adit assayed 17.72 per cent lead, 18.91 per cent zinc, 1991 grams per tonne silver and 0.400 per cent antimony (Chapman, J. (2018-07-15): National Instrument 43-101 Technical Report on the Silver Dollar Property).

The Main vein on the No. 2 level consists of solid bands of sulphides and disseminations, up to 3 metres wide, in a graphitic shear zone for a length of 24 metres. In the most easterly workings of the intermediate level, the ore zone follows a parallel, partly mineralized structure trending 138 degrees and dipping 60 degrees northeast.

In 1918, sampling of the raise from the No.2 adit assayed 2.0 grams per tonne gold, 2387 grams per tonne silver, 16.1 per cent lead and 31 per cent zinc over 0.6 metre (Property File - A.E. Wooton [1959-04-01]: A Mineralographic Study of Ore from the Beatrice Mine).

In 1964, a sample (80331) from the top of the raise on the No.2 level assayed 0.7 gram per tonne gold, 273.6 grams per tonne silver, 3.39 per cent lead and 6.51 per cent zinc over 0.96 metre, while a sample (80332) from the sub-level yielded 0.7 gram per tonne gold, 1108.1 grams per tonne silver, 12.74 per cent lead and 12.50 per cent zinc over 0.84 metre (Property File - Dakota Silver Mines Ltd. [1964-09-08]: Report on the Beatrice Property).

In 1986, sampling of the Main vein on the sublevel drift yielded 0.7 gram per tonne gold, 1110.5 grams per tonne silver, 11.39 per cent lead and 18.2 per cent zinc over 0.54 metre, whereas sampling of the No.2 level yielded up to 0.7 gram per tonne gold, 91.3 grams per tonne silver, 0.86 per cent lead and 2.09 per cent zinc over 1.23 metres (Property File - Dunhill Resources Corp. [1988-01-22]: Geological Report on the Beatrice Property).

A third mineralized quartz vein, known as the Gold Lode, has been traced for a few hundred metres in opencuts below the main road and approximately 180 metres northeast of the Main vein. This vein contains pyrite and a sprinkling of galena. It is 1.2 to 1.8 metres wide, strikes 155 degrees and dips steeply to the northeast. Assay results returned 5.1 grams per tonne gold and 32.5 grams per tonne silver (Annual Report 1914, page 267).

In 1982, a possible resource of 5715 tonnes grading 465.1 grams per tonne silver, 5.1 per cent lead and 10.9 per cent zinc was reported (Property File - R.C. Hart [1982-12-01]: An Analysis of Reports on the Beatrice Property). This included previously broken material left as backfill and muck.

In 1988, an estimated geological reserve of 1360 tonnes grading 0.2 gram per tonne gold, 393.0 grams per tonne silver, 4.03 per cent lead and 7.78 per cent zinc was reported for the Main vein, with another 2177 tonnes grading 0.5 gram per tonne gold, 74.9 grams per tonne silver, 0.70 per cent lead and 2.08 per cent zinc (Property File - Dunhill Resources Corp. [1988-01-22]: Geological Report on the Beatrice Property).

During 1899 through 1917 and including 1984, a total of 618 tonnes of ore was shipped from the property yielding 558 grams of gold, 1832 kilograms of silver, 182 930 kilograms of lead and 10 894 kilograms of zinc.

The Beatrice and Folsom claims were staked in 1897 and Crown granted in approximately 1902. They were originally part of the Beatrice Group, located on the southwest spur of Mount Pool. The original discovery by two prospectors consisted of a small chimney of clean galena at the contact of schist and crushed slate. A 10-metre shaft was sunk on the ore, which was further developed by a 60-metre adit-tunnel, known as the No. 1 level. The No. 2 level was driven from the opposite side of a shoulder (jutting north from the main ridge) to a vertical depth of 46 metres below the No. 1 level. In 1898, approximately 200 tonnes of silver-rich ore were hand mined.

The property was worked continuously from 1898 to 1906. In 1902 the Beatrice Mines Ltd. was organized. The company resumed operations in 1910, but ceased work in 1911. In 1918 the property was bonded to New Era Mines Ltd. and operations continued through 1920. At this point the workings consisted of several hundred metres of drifts, crosscuts and raises on three levels. In 1921, a two-bucket tramway was installed to connect the No. 2 adit with ore bins on the main trail; however, the high zinc content of the ore prevented satisfactory market arrangements at the time and this discouraged further work.

In 1954, a private company, Beatrice Mines Ltd., rehabilitated the mine and rebuilt the road during the next few years. In 1964, the property was optioned to Dakota Silver Mines Ltd. During 1964 and the following years, limited work was carried out but the property and equipment was eventually abandoned. In 1977, Arch Mining and Milling examined and sampled the area. In 1980, Taseko Mines completed a program of geochemical sampling and five diamond drill holes, totalling 300 to 450 metres. In 1984, 412 tonnes of dump material from the No.1 adit were shipped to the David Minerals mill at Ainsworth, where lead and zinc concentrates were produced and treated at the Cominco smelter. In 1985 and 1986, Tyner Mining examined the area. In 1987 and 1988, Dunhill Resources completed programs of geological mapping and geochemical sampling.

During 2012 through 2014, Happy Creek Minerals Ltd. examined the area as the Silver Dollar property and a complete exploration summary can be found at the Silver Dollar (082KNW101) occurrence. In 2016 and 2017, Explorex Resources Inc. completed programs of prospecting and rock and soil sampling on the area as the Silver Dollar property. In 2019, Mariner Resources Corp. completed a 624 line-kilometre airborne magnetic and radiometric survey on the area as the Silver Dollar property.
