Several styles of mineralization occur from gold-bearing iron sulphides in the north to silver-rich galena and sphalerite in the south.

 

The Gilman sector includes the Gilman, Beatrice and Silver Dollar historic occurrences.  Gilman reportedly shipped fourteen tonnes of mineralized material in 1933 grading 69.9 g/t Au and 89.1 g/t Ag. From the Silver Dollar occurrence, the Silver Pass Development Syndicate is reported to have processed six tonnes in 1947 of mineralized material and recovered 9,860 g of silver, 1,378 kg of lead, and 1,009 kg of zinc.

 

From the Beatrice in 1899 to 1917 and 1984, a limited amount of material was shipped from the property (believed to be 618 tonnes of hand sorted rock). Of the 618 tonnes shipped, 34 tonnes was milled off site and yielded 558 grams gold, 1,832 kilograms silver, 182,930 kilograms lead and 10,894 kilograms zinc.

 

Mineralization at Beatrice, consisting of galena, sphalerite, tetrahedrite and pyrite occurs as irregular veins within shear zones, on bedding slips and cross cutting faults. The veins range in width from a few centimeters up to 2 to 3 metres wide.  A third vein, known as the Gold Lode, was exposed in a series of open cuts (since covered) over a distance of “a few hundred metres” parallel to an access trail. This vein, reportedly up to 1.8 metres wide, returned grades up to 5.1 g/t Au and 32.5 g/t Ag as recorded in a 1914 annual report. The vein had a strike of 155 degrees and a steep northeast dip.

 

Work in 2016 by Explorex confirmed a number of the historical occurrences:

#1067856:  7.41 g/t Au & 32.5 g/t Ag (grab sample vein material at Silver Dollar main adit);

#1067859: 13.01 g/t Au & 18.5 g/t Ag (30cm chip sample from unnamed vein in outcrop at Silver Dollar);

#1067861: 57.10 g/t Au & 108 g/t Ag (grab sample at Gilman vein).

Explorex has completed a soil survey, designed to extend the Beatrice mineralization onto underexplored ground.
