Very little is known of this deposit as it was one of a number of small, silver-lead deposits opened in the Revelstoke-Nelson area in the late 19th Century. The International Mine is 56 kilometers south of Nelson. The B.C. Government website calls it the Reeves McDonald Mine and says: Sulphides occur as well-laminated bands and lenses of massive and disseminated pyrite, honey-colored sphalerite and galena in a medium to dark grey banded dolomite. Laminations are generally discontinuous and locally highly contorted. Commonly, the ore is brecciated, particularly on the synclinal limbs and the breccias contain rounded to angular, rotated fragments of dolomite and limestone in a sulphide matrix. Breccias are usually rich in pyrite. The ore is cut by narrow veinlets of coarsely crystalline white calcite, dolomite, and quartz with minor sphalerite and galena.
