Exploration History

In 1936 Noranda Mines conducted an extensive program of prospecting, geological mapping, trenching, sampling, magnetic and electromagnetic surveys and a diamond-drilling program of 17 holes. An inferred and indicated resource of 72 500 t grading 11.7 g/t gold was calculated to a depth of 107 m. In about 1940, a 20-foot shaft was sunk. In 1983 Duncan Gold Resources diamond drilled 2 holes. In 1984 the company completed a stripping and washing program outlining a breccia pipe, a 59-hole percussion drilling totalling 2098 feet, a 12-hole, 800 foot Winkie diamond-drilling program and a six-hole, 3648-foot BX diamond-drilling program. This program increasedthe resource to 225 000 t grading 6.9 g/t gold to a depth of 229 m. A 1.36 t sample was collected for metallurgical testing in a small pit (Pearson 1985). In 1987 a 8000 ton bulk sample averaged 0.11 ounce per ton gold (Northern Miner, August 1, 1988, p.13). In 2009 and 2010 Creso Exploration completed geophysics, diamond drilling and dewatered the pit.

Geology Comments

Dec 21, 2011 (D Guidon) - The rocks underlying and surrounding the pit area are composed mainly of intermediate to felsic flows and breccias with local basaltic flows. Ore grade zones are related to K2O enrichment and elevated amounts of pyrite. The zone is pipe-like with a diameter of about 20 m (Harron and White 2010). The margins of the pipe may have more rounded clasts, whereas the internal portions are more angular. In 2010, diamond-drill hole MC-09-01 was deepened in 2010 from 269 m to 920 m. A section from 508.5 to 591.4 m averaged 13.3 g/t gold. (Creso Exploration Inc. 2010). The hole was drilled at a steep angle to the southeast. Diamond-drill core from 505.5 m to 617.9 m was examined in September 2010. Units included grey feldspar porphyry (505.5-506.5 m), dark grey mafic volcanic cut by quartz-carbonate veining (506.5-508.5 m), ultramafic breccia (508.5-510.0 m), mafic volcanic breccia healed with quartz-carbonate and disseminated pyrite (510.0-516.5 m), reddish feldspar porphyry (516.5-526.8 m), felsic to intermediate breccia healed with quartzcarbonate and disseminated pyrite (526.8-588.4 m) and red-grey, medium-grained syenodiorite (588.4-617.9 m). Breccia zones contain about 15% quartz-carbonate with 1 to 2 mm disseminated subhedral pyrite and visible gold. Faults cutting the breccia are indicated by a quartz-healed crushed interval. Drilling has indicated an upper and lower zone to the deposit, separated by a mafic dike about 150 m thick. Gold mineralization may be present in veins of diverse orientations hosted in pyritic chlorite breccias.

Geologist: D Guidon

Notes: Property examination September 27, 2010 with Gary Grabowski. Doug Robinson showed us drill core at the Tyranite site and then visited the pit that had been dewatered. The pit was partially filled due to a large rainstorm. Pit visited again September 30 after it was almost pumped out again.
