Exploration History

1958 - 1961: Algoma Ore Properties – DD – 3 – 926ft, Assays, DD – 9 – 2425ft, GL, Mag. 1972: Dome Exploration carried out a diamond drill program over two years following an airborne geophysical survey during which the intersection described here was obtained. 1980: Domex resumed their exploration program with a ground magnetic survey and second drill program. 1983: G. Sanford – Tr. 1984: G. Sanford – Str. 1987: A joint venture gold exploration program was carried out in the area by Marshall Minerals, Gail Resources, and Gold Vessel Resources. This work consisted of geophysical surveying, mapping, stripping and diamond drilling largely directed towards the Hoodoo Occurrence to the southwest. 2003 : George Ross, Fred Ross, Garry Windsor – Assays, Beep, Pr, Samp, Tr. 2006: Amador Gold Corp. – EM, Mag.

Geology Comments

Dec 07, 2005 (S Fumerton) - Mineralization tends to occur along the contact between the iron formations and the ultramafic metavolcanics.

Peridotite	3	Peridotite	Spinifex	Host

Lithology Comments

Dec 07, 2005 (S Fumerton) - Pyritic bands forms up to 15% of a sulphide facies banded iron formation which forms a repetitive cycle intercalated with ultramafic metavolcanics. Other phases in the iron formation consist of cherts with disseminated fine grained pyrite together with magnetite together with carbonate veins. The ultramafic metavolcanics are serpentinized, and chloritized with local carbonatized sections. Within this rock there are sections with very fine pyrite - magnetite.

2	Pyrrhotite	Economic	Gangue
	Serpentine	Alteration		Serpentinization	1	Medium	Replacement

Mineralization Comments

Dec 07, 2005 (S Fumerton) - Traces of base metals occur in both the iron formations and the adjacent peridotites. Within the peridotite, sulphide mineralization tends to be restricted to finely disseminated pyrite. In contrast, within the iron formations, streaks of pyrite and pyrrhotite occur with local traces of chalcopyrite.

Mar 19, 2015 (P Bousquet) - The best assay returned 0.112% Ni over 8.2 ft. The best Zn and Cu values were 0.45% Zn and 0.100% Cu over 9.7 ft, and 0.40% Zn and 0.125% Cu over 10.7ft (T-249).
