Capsule Geology

The Kruger prospect is located at 720 metres elevation, 900 metres west of the main adit on the Lakeview (Lot 1899) Reverted Crown grant. The prospect is covered by ground staked as the Kruger Mountain claim. Osoyoos is located 4 kilometres to the northeast.

Markus Resources Ltd. staked the Kruger Mountain claim in 1986 and conducted property exploration programs in 1986 and 1987. Three abandoned adits were discovered near the east-central portion of the Kruger Mountain claim. In 1991, the ground was staked as the Blue Ox claims and further exploration was done on the area surrounding the Kruger prospect by G.E. Keller and associates.

The regional geology of the Dividend-Lakeview area consists of medium to coarse-grained granodiorite of the composite Middle Jurassic Similkameen batholith. To the west this includes alkali syenite and nepheline syenite of the Kruger intrusion. The Similkameen intrusion extends from 10 kilometres north of the Canada-United States border, south into Washington state. The granodiorite is grey-green, medium to coarse grained and dominantly composed of quartz, plagioclase and hornblende. The Similkameen batholith has intruded metasediments and metavolcanics of the Carboniferous to Permian Kobau Group. Intensely folded and metamorphosed quartzite, greenstone, phyllite, chlorite or mica schist with intercalations of dioritic rocks and sparse limestone lenses comprise lithologies. To the west lie a series of highly sheared schists, greenstones and quartzites known informally as the Kruger Schists. The greenstone has been highly sheared in many areas associated with emplacement of the Similkameen intrusion and other intrusions. Shear zones strike southeast and dip moderately to steeply northeast and southwest. Local variations occur however.

Kruger prospect is hosted in metasediments and metavolcanics of the Kobau Group, near its contact with granite, granodiorite and monzonite of Osoyoos granodiorite, a satellite stock of the Similkameen batholith. Two lenticular skarn bodies were discovered during property exploration in 1986. They are known as the Skarn A and Skarn B zones and were previously explored by three adits. These bodies are 1.0 to 1.8 metres wide, up to 20 metres long, strike 305 degrees and dip 28 degrees northeast. The skarn is composed of approximately 40 per cent silica, 20 per cent calcite with garnet, epidote, diopside, tremolite and small amounts of pyrrhotite and locally chalcopyrite.

The Skarn A zone lies 100 metres southwest of the Skarn B zone. The zone contains several small lenses of epidote, garnet and garnet skarn which occur adjacent to a shear zone in graphitic quartz schist, chlorite schist and quartzite. Discontinuous quartz veins are also located within this shear zone. Several dikes also occur within or adjacent and parallel to the shear zone. Two samples were taken from adit dumps in 1986. Sample 86KB25 was taken from an opencut along the shear zone. It yielded 4.95 per cent copper, 23.2 grams per tonne silver and 3.80 grams per tonne gold (Assessment Report 14877). Chip sample 86KB46 was taken across 1.0 metre of quartz-feldspar- epidote-garnet skarn and yielded 0.27 per cent copper, 0.90 gram per tonne silver and 0.09 gram per tonne gold (Assessment Report 14877). In 1987, grab sample TC-87-037 was taken of quartz vein material from the opencut dump. It yielded 0.50 per cent copper, 39.70 grams per tonne gold and 36.50 grams per tonne silver (Assessment Report 16074).

The Skarn B zone consists of a main east trending skarn lens and several smaller lenses in or adjacent to the shear zone. The dominant hostrock is greenstone. Several samples were taken with the following results. Sample 86KB47 was a 1.0 chip sample across skarn with no visible mineralization. It yielded 2.1 grams per tonne silver and 0.09 gram per tonne gold (Assessment Report 14877). In 1987, follow-up sample TC-87-034 from sheared greenstone near this skarn zone yielded 1.4 grams per tonne silver and 0.05 gram per tonne gold (Assessment Report 16074).
