The Lois Lake showing is located in the eastern head waters of Holt Creek, approximately 1.5 kilometres north west of Wild Deer Lake.

The area is underlain by Vancouver Group rocks of the Upper Triassic Karmutsen Formation, comprised of massive and pillowed basalt with minor basaltic lapilli tuff. The rocks are characteristically green-black and pillows are irregular with quartz and chlorite selvages and infillings. The volcanics are crosscut by a series of ankerite, quartz and hematite veins.

The most significant mineralization occurs as quartz-ankerite veins in the mafic volcanics. Four vuggy quartz-anderite veins, 10 to 30 centimetres wide, are surrounded by carbonate alteration envelopes up to 0.5 metres wide, striking northwest and dipping moderately to steeply southeast. In one vein a 1.0-metre wide clay zone hosts disseminated to blebby freibergite with malachite and azurite.

Work History

In 1987, Nexus and Goldenrod resources completed a program of geochemical sampling and geological mapping on the Holt 1-15 claims. A sample (4477) assayed 0.15 grams per tonne gold, 3600 grams per tonne silver, 0.953 per cent antimony, 0.299 per cent zinc, 0.795 per cent arsenic and greater than 1 per copper (Assessment Report 16059).

In 2006, D. Herriott completed a program of prospecting on the area as the Silver Nugget claims.

In 2018, Island Time Exploration Ltd. completed a program of geological mapping, prospecting, geochemical (soil, silt and rock) sampling and an airborne magnetometer survey on the area as the Holt property.
