The Black Diamond (Lot 1098s) past producer is located 2.75 kilometres west of the summit of Goat Peak and 3.0 kilometres south-southeast of Beaverdell, British Columbia (Assessment Report 16772).

Initial prospecting began in the Beaverdell area in the late 1880s. The first ore was shipped in 1896. The major producing mines in the Beaverdell silver-lead-zinc vein camp, from west to east, were the Wellington (082ESW072), Sally and Rob Roy (082ESW073), Beaver (082ESW040), and Bell (082ESW030), with numerous other small workings throughout the area.

Past development on the Black Diamond began in 1916, under operation by P.J. Kennedy. A shipment of ore was made in 1918. In 1925, a syndicate of Penticton men continued development but failed to find further ore before funds ran out. A new strike was claimed to have been found in 1927 by Kennedy but no ore was mined. Since 1946, work has been intermittent and ownership has changed several times: 1946 - Silver Bounty Mines Ltd., 1958 - Sheritt-Lee Mines Ltd., 1963 - Ruby Silver Mines Ltd., 1971 - Copper Bounty Mines Ltd. and 1983 - Walmont Precious Metals Corp. The occurrence is currently owned by IGF Metals Inc. Past development included a 30-metre crosscut, 3 inclined shafts, the deepest being about 30 metres, and 46 metres of opencuts and drifts.

For a detailed description of the geology and mineralization of the area refer to the Beaverdell (082ESW030).

The Black Diamond (Lot 1098s) and Standard (Lot 1099s) partially overlie one another and adjoin the Standard Fr. claim (082ESW035) in the southwest. The property is underlain by Westkettle batholith granodiorite. An east trending shear zone, possibly a continuation of a shear zone on the adjoining Standard Fr. claim, contains quartz veins and veinlets carrying silver values. The shear zone is highly fractured and oxidized with limonitic and hematitic alteration and manganese staining (pyrolusite). Some clay gouge is also present in the zone.

Mineralization within the quartz veinlets is unknown. Where exposed on the easterly neighbouring Standard Fraction, the vein carries galena, pyrite, sphalerite, tetrahedrite and chalcopyrite. IGF Metals Inc. sampled shears and veins on the Black Diamond in 1987. Sample #8 yielded the best results of 7 channel samples across the main shear zone. This sample contained 3.08 grams per tonne silver and 0.03 gram per tonne gold (Assessment Report 16772).

Production records indicate 2 tonnes of 'silver ore' was shipped in 1918 to the Trail smelter, from which 746 grams of silver were recovered.
