The Mary Reynolds property hosts a major north-northeast trending gold-silver bearing shear zone which has been subjected to clay and quartz-carbonate alteration. This shear zone, zone A, is the largest and strikes north-northeast and dips vertically or steeply to the west-northwest. Past development has been confined to the silver-rich shears in the southern portion of the main structure. The main zone appears to pinch out to the north-northeast and broadens to the south-southwest. It has an overall strike length of 1050 metres and widths of 40 to 300 metres. Detailed mapping has shown that the zone is comprised of smaller individual shears that vary in width from 1 to 3 metres and in length from 60 to 500 metres. Mineralization occurs sporadically within quartz-carbonate veining and comprises very fine-grained pyrite, galena and sphalerite with minor tetrahedrite and chalcopyrite. A rock sample assayed 0.51 per cent lead, 1.46 per cent zinc, 239.27 grams per tonne silver and 0.82 grams per tonne gold (Assessment Report 17163).
South of the main zone A, the trace of the main shear structure swings to a north-south orientation. Approximately 750 to 900 metres south of zone A, old trenches and an inclined shaft has exposed a broad zone of weakly to moderately carbonate-altered andesite hosting one or more quartz veins. Grab rock samples of quartz vein dump material mineralized with pyrite and galena assayed up to 166.94 grams per tonne silver and 2.33 grams per tonne gold (Assessment Report 18714).
Four new mineralized zones, B, C, D and E, have recently been discovered in moderately southwest dipping andesitic flows. Steeply dipping, north to north-northwest trending Tertiary shear zones truncate the flows. The shear zones are comprised of smaller individual shears which vary in width from 1 to 3 metres and have been traced for a strike length of a couple of metres up to 500 metres. The shears exhibit various degrees of clay alteration with quartz-carbonate veining and silicification. The altered zones are in sharp contact with unaltered andesite. Sulphide mineralization is hosted by the veins and consist of very fine to fine-grained pyrite, galena and sphalerite with occasional chalcopyrite and tetrahedrite. Precious metal values are associated with the sulphides.
Zone B is located 300 metres west-northwest and parallel to the main zone A. It comprises an area of discontinuous north trending shears that dip vertically to 67 degrees west. The shears range from 1 to 3 metres in width, are clay altered and may contain chalcedonic quartz veining. Sulphides are associated with the veining and are comprised of very fine-grained pyrite and minor galena. A rock sample from the surface workings assayed up to 0.3 per cent lead, 0.32 per cent zinc, 145.4 grams per tonne silver and 1.42 grams per tonne gold (Assessment Report 17163). A diamond-drill hole tested the zone immediately below the main area of old workings. The hole cut a large number of narrow mineralized zones of which two are 7 to 10 metres wide. The best intersection returned 1.5 grams per tonne gold and 290 grams per tonne silver across 0.78 metres (Assessment
Zone C is 1500 metres northeast of the main zone A and 750 metres east of and roughly parallel to zone D (North showing). It comprises discontinuous north-northeast trending shears that dip 55 to 65 degrees to the east-southeast, are 1 to 2 metres in width, and are within clay-altered lithic fragmental rocks cut by quartz veins. Minor very fine-grained pyrite occurs. A rock sample assayed 10.2 grams per tonne silver and up to 3.85 grams per tonne gold (Assessment Report 17163). Diamond drilling returned a best intersection of 0.245 grams per tonne gold and 1.2 grams per tonne silver across 0.6 metres (Assessment 18714).
Zone D (North showing) is approximately 900 metres north of the main zone A. It is at the intersection of a north-northeast trending and a north-northwest trending shear structure 1.2 to 1.5 metres wide. The rocks are clay-altered, limonitic, with no silicification. Gold values of 10.1 grams per tonne and 3.4 grams per tonne silver over 1.5 metres have been previously reported (Assessment Report 17163). Diamond drilling returned a best assay of 2.19 grams per tonne gold and 4.6 grams per tonne silver across 0.9 metres (Assessment Report 18714).
Zone E is 250 metres south of the main zone A and comprises a one metre wide northwest trending shear zone that dips 75 degrees northeast. Mineralization is hosted by quartz-carbonate veins in limonite altered andesite and is comprised of pyrite with lesser galena. A rock sample assayed 4.59 grams per tonne gold and 350.6 grams per tonne silver, 19.1 per cent lead and 10.84 per cent zinc (Assessment Report 17163).
