The area of the Westmore showing is predominantly underlain by rock of the Devono-Mississippian Stikine Assemblage. Dioritic stocks of the Late Devonian Forrest Kerr Plutonic Suite intrude the stratigraphy.

Gold bearing quartz veins and veinlets have been mapped on the northwest bank of More Glacier within and adjacent to a granodiorite plug intruding a package of intermediate to mafic volcanics and volcanic and sedimentary phyllites. These veins occur in a dense, sub-parallel swarm over a 150 by 100 metre area. The granodiorite plug is post-Triassic and probably related to a regional Jurassic intrusive event. The veins are up to 2 metres thick and generally strike 255 degrees to 285 degrees, dipping moderately to steeply to the north, although shallowly-dipping and southerly-dipping veins also occur. The veins can be continuous over 100 metres and consist primarily of coarse, milky bull quartz with coarse grained disseminated pyrite. Some veins contain minor disseminated sulphides (galena, sphalerite, chalcopyrite, pyrite) and have sericitic margins. These veins contain gold mineralization. Texturally and mineralogically these veins are different than the white veins with coarse crystalline pyrite, which also carry gold mineralization. Quartz veins swarm over a length of nearly 1000 metres.

In 1988, Cominco Ltd. was reported to have discovered a gold rich quartz vein source at the Westmore location.

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 conducted geological mapping and sampling over the Westmore gold veins and boulder fields. Roca cored 11 drill holes in 1121 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. Three holes totalling 2033 metres were drilled along near the Ryder showing (new MINFILE), intersecting significant intervals of low-grade sphalerite and chalcopyrite mineralization. Airborne geophysics (magnetics and electro-magnetics) was flown covering the present extents of the North Zone, as well as other mineralized areas. The Ryder showing is about 3 kilometers northeast of the North showing (104G 148).

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 km. A total of 52.6 line kilometre of Induced Polarization (IP) surveys and 57.7 line kilometre 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). Holes were drilled into the HV, SBF, Ryder, BRT and Westmore. No drilling was completed in the Antler area. Westmore drilling was done in North zone area (104G 148). Some rock sampling occurred in the Westmore MINFILE location (104G 184) (Westmore Property Geology map and Appendix C (Rock Samples) 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.

In 2019, Sassy Resources Corp. completed a program of prospecting, geological mapping and geochemical sampling on the area as part of the Foremore property. Grab samples (B0020728 and B0020723) from the Westmore area yielded up to 126 grams per tonne gold, 1900 grams per tonne silver, 9.01 per cent copper, 0.21 per cent zinc and 1.56 per cent lead, whereas two chip samples (B0020721 and B0020722) yielded 120 and 81.1 grams per tonne gold, 1040 and 987 grams per tonne silver, 0.21 and 0.40 per cent zinc with 0.71 and 0.83 per cent lead over 0.20 and 0.30 metre, respectively (Sassy Resources Corporation [2019-12-31]: Amended Independent Technical Report - Foremore Au-Ag-Cu-Zn-Pb Property, British Columbia).
