11/25/1999 (P Hinz) - W.C.H. Little describes the geology: The chief rock exposures are basic lavas which have been altered to sericite, chlorite and in some places andalusite schist. There appear to be two different lines of weakness. Two claims are crossed by a large porphyry dike striking north 35 degrees east, the schisting following the dike. On the claims to the north of this the schisting is north and south corresponding with a pronounced burn (Schnieders and Dutka, 1985).

11/25/1999 (P Hinz) - W.C.H. Little describes the mineralogy: A siliceous quartz porphyry dike striking north 35 degrees east contains quartz veins striking in the same direction and dipping about 70 degrees to the north. From what shows in the only pit on this vein, the quartz is widening downwards and the south wall still shows stringers of quartz. A chipped sample taken over a width of 7 feet gave $ trace gold and % copper. The owner claimed to have got over 3 % copper here, which seems doubtful. The porphyry plunges into the swamp to the west; it is stated on reliable authority to be traceable for half a mile further, but work which has only been done this year has been considered in the pit which owing to the slope of the hill exposes the vein well.” F. Spence (1928) described the property as follows: “The other property is situated some six miles from the Mayflower, half a mile from the track and the same distance from the Backus powerline. This is an enormous quartz porphyry dike and was just staked the latter end of May. This dike varies from 300 to 500 feet in width and extends over one mile in length. There has been no work don eon this and only surface assays which run 20 cents, $1.92, $13.40, and $18.00, in gold with a 5 percent copper content.” (Schnieders and Dutka 1985).
