Capsule Geology

The SG zone of the Foremore property is predominantly underlain by the Devono-Mississippian Stikine Assemblage.

Mineralization occurs in a felsic tuff unit located between an overlying sericite altered rhyolite and an underlying limestone/mafic sill unit. The felsic tuff/rhyolite are typically apple green and massive, however fragmental tuffaceous textures and rare flow banding are visible. The massive mineralization is associated with calcite bearing stringer type mineralization which cuts across stratigraphy. This crosscutting and discontinuous nature of mineralization are indicative of stringer style or remobilized mineralization.

Late during the 2002 field program, lead-zinc mineralization on the Foremore property’s SG Zone was trenched by Roca Mines Inc. using drilling and blasting techniques, resulting in the exposure of precious metal enriched massive lead-zinc-arsenic mineralization. Until this point, only thin discontinuous stringers of zinc-lead mineralization were visible.

In the area where massive mineralization was exposed, a 1.9 metre composite of 2 samples assayed 1.63 grams per tonne gold, 13.0 grams per tonne, silver, 1.62 per cent zinc, and 0.24 per cent lead, (Assessment Report 27398).

The best channel sample in the SG zone graded 2.34 per cent Lead, 6.69 per cent zinc, 42.9 grams per tonne silver, 0.11 gram per tonne gold across 1.82 metres but the four holes drilled through the horizon returned lower grades (Exploration and Mining in BC 2003, page 10).

In 2004, two drill holes put down on strike of the SG lead-zinc-silver-gold showing determined graphite to be the cause of an EM conductor surveyed in 2003.

Work History

In 2002, Roca optioned the Foremore Property and staked additional mineral claims. Equity Engineering Ltd. of Vancouver was contracted to carry out a program of mapping, prospecting and geochemical sampling on the property.

In 2003, Roca cored 11 drill holes in 1,121 metres.

In 2004, Roca carried out property scale prospecting, ground geophysical surveys and cored 37 drill holes totalling 5900 metres.

In 2005, Roca cored 4 drill holes totalling 2,033 metres and completed geological mapping, rock and soil sampling surveys. In August a 700-line kilometre helicopter supported airborne magnetometer and electromagnetic survey was flown over 50 per cent of the property. The integration of new and historic data into the MapInfo platform was initiated.

In late August 2006, the Property was flown for orthophotography.

In 2007, Roca carried out a detailed mapping program in the Hanging Valley. A total of 149 rock and 231 soil samples were submitted for chemical analysis (Assessment Report 29475). Mineralized areas discussed include SG (104G 181), Antler, Zig Zag, Boulder and Heather. At least one sample was taken in the SG area.

In 2008, Roca conducted a program included gridding in four areas totalling 78.0 line kilometres. A total of 52.6 line km of Induced Polarization (IP) surveys and 57.7 line kilometres of Total Field Ground Magnetometer surveys were completed. In addition, 3,299.4 metres of drilling was completed in 13 holes from which 890 samples were submitted for analytical work. During the course of geological mapping a total of 301 rock and 197 soil samples were submitted for chemical analysis. Mapping occurred in several areas including the HV/SBF, Roca Flats, Ryder, Westmore and Antler areas. One bedrock grab sample (926005) of heterolithic felsic agglomerate located 500 m west of the SG showing yielded 0.75 per cent copper (Assessment Report 30246).

Field work during 2011 by Roca consisted prospecting and geochemical sampling. This work concentrated on the hillside around the SG zone, a gold-rich volcanic hosted massive sulphide showing. The 2011 work involved collecting 818 soil samples at 25 metres spacing along the northwest slope of the hanging valley in an attempt to locate the source to the South Boulder Field an area comprised of sulphide-rich boulders and blocks that carry base and precious metal mineralization. Dispersion patterns of elements in soil indicated a large anomalous area below the SG showing and down slope from the Sunday showing (104G 182).

In 2019, Sassy Resources Corp. completed a program of prospecting, geological mapping and geochemical sampling on the area as part of the Foremore property. Two samples (B0020958 and 1291751) from the SG occurrence area yielded an average of 11.9 per cent zinc, 7.7 per cent lead and 12.8 grams per tonne gold, whereas another outcrop grab sample (1291656), taken to the east of the occurrence, assayed 3.39 grams per tonne gold, 8.9 grams per tonne silver, 0.72 per cent zinc and 4.86 per cent lead (Sassy Resources Corporation [2019-12-31]: Amended Independent Technical Report - Foremore Au-Ag-Cu-Zn-Pb Property, British Columbia).
