Capsule Geology

The Tip Top-Nevada occurrence is located on the lower eastern slopes of Thimble Mountain, west of the Granby River.

The area is underlain by limestone, greenstone and undivided sediments of the Triassic Brooklyn Formation, which is intruded by small diorite dikes and bounded to the north by granodiorite of the Cretaceous Anstey pluton and to the south by greenstone.

Locally, on the Nevada (L.1365) Crown grant, a 15-metre long adit follows a 20 to 30-centimetre wide shear zone with in epidote altered greenstone. The shear zone trends 315 degrees with a dip of 45 degrees to the north and hosts weak patchy pyrite-chalcopyrite-galena mineralization.

The Tip Top (L.1367) occurrence is located approximately 200 meters uphill and west of the Nevada occurrence and is reported to likely represent the north western on-strike continuation of the Nevada shear zone. At the Tip Top occurrence, a narrow (20-centimeter wide) mineralized shear zone trends 330 degrees and dips 90 degrees in bleached epidote altered greenstone and has been tested by an adit and shaft or chimney. The shear zone is mineralized with patchy pyrite, pyrrhotite and chalcopyrite.

The Bluebird (L.1363) occurrence is located approximately 1300 meters to the southwest of the Tip Top-Nevada occurrences and 350 meters west of, and steeply uphill from the rail-grade. The occurrence comprises an epidote-quartz-pyrite skarn is developed within limestone, sharpstone conglomerate and calcareous sandstone, near the contact with overlying volcanics. Several old pits poorly expose skarn, mineralized with minor clots and disseminations of galena and chalcopyrite, over an area of about 100 square meters. Nearby, a 0.5 to 1.5-meter wide quartz-calcite vein has been tested by a short open cut at the base of a steep cliff-like outcrop. The vein is weakly mineralized with chalcopyrite.

In 2006, select grab samples from the Tip Top occurrence yielded up to 3.18 grams per tonne gold, 600 grams per tonne silver, 3.7 per cent copper and 0.41 per cent zinc, while select grab samples from the Nevada occurrence yielded up to 344 grams per tonne silver, 6.05 per cent copper, 0.36 per cent lead and 0.32 per cent zinc (Caron, L. (2010-07-09): National Instrument 43-101 Technical Report on the Eholt Property).

The area has been explored in conjunction with the nearby Seattle (MINFILE 082ESE158) occurrence and a complete regional exploration history can be found there.
