NTS Grid: 41O16NW

Point Location Description: Stripped and trenched area near the #1 claim post for cancelled claim 619051

Location Method: Field Visit with GPS

Access Description: A secondary road which leads to Horwood Lake passes within 400m of the stripped areas and a trail leads directly to the showing. This secondary road branches off the road leading to the Orofino Mine site and Newton township which in turn branches off the Dore Main Haul road.

Exploration History

1982 Messrs R. Wdowczyk together with Jim Landers started stripping and trenching a number of areas north of the Orofino Property centered on an old, unreported trench. This manual and mechanical work combined with one short drill hole was carried out over the next ten years. The results of this work indicated gold up to 2 g/t can be obtained in a number of showings scattered over eight claims and up to 3.5% Cu but the latter is even more restricted. 1991 Noranda Exploration carried out a reconnaissance VLF-EM survey over the northern Wdowczyk showing as part of a property visit. 1991 American Barrick sampled the showing during a property visit and reportedly obtained good assay results up to 30 g/t in two samples.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - Thin quartz vein form an erratic stockwork in a medium grained massive basaltic flow, probably of iron tholeiitic affinity. The metavolcanic has pervasive though low intensity chlorite and carbonate alteration. Five hundred metres to the southwest in another stripped area, similarly altered massive and pillowed flows have a stockwork of closely spaced fracture with some fine grained white quartz in the fractures associated with extensive pyrite mineralization.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - At the main showing there are a number of shallow dipping quartz veins forming a stockwork which is thinly and erratically distributed. The quartz veins, with minor iron carbonate, are thin being less than 10cm, very coarse grained, granular and variable in colour from white, to pale translucent green, and grey. Pyrite and trace amount of chalcopyrite form up to 10% of the veins in coarse subhedral grains though the distribution is erratic. The sulphides also occur in the adjacent wall rock but the size and percentage decreases away from the veins. At the secondary showing to the southwest near the cabin, coarse euhedral pyrite and minor chalcopyrite forms up to 10% of the rock within 2cm of the fracture stockwork. Further from the fracture stockwork pyrite is finely disseminated through the matrix forming 2 to 5% of the rock over an exposed area about 10m across.

Geologist: J Ireland

Notes: Together with Lorne Luhta, Resident Geologist: Tom Lewis, geologist with Noranda Exploration, the writer accompanied Messrs Jim Landers and Bob Wdowczyk to their property in Horwood Township. The purpose of the visit was to examine, sample an locate mineralized showings for later mapping. The first showing is located 1450m along the road west of the creek at Stangiff Lake, north of the road and east of a small creek running north to the Swayze river. A small exposure of mafic pillowed volcanics has been hydrothermally altered and autobrecciated. Solutions passing through the rock deposited quartz, carbonate and pyrite as well as producing hematitic staining which preferentially replaced pillow selvages and filled amygdules, vesicles and fractures. Fine grained disseminated pyrite (0.5 to 1%) was observed in more massive volcanics up to 100 feet away from the autoclastic zone. Pillow tops are to the southwest. The second area visited is located 800m east and 370m north of the first zone. Recent stripping has exposed 2 quartz carbonate pyrite veins in an area spotted with several old trenches and blast pits. The veins appear narrow (10 - 40cm), discontinuous and irregular, dipping gently north to gently south. They have a consistent east west trend along strike. Mineralization consists of a sub to euhedral pyrite cubes: from 1 - 15mm in size, within and peripheral to the quartz veins. Disseminated pyrite blebs and accumulations are prevalent in the wall rock adjacent to the veins. Host rocks are medium grained, chloritized to amphibolitic massive and pillowed mafic volcanics. They have been intruded by later fine grained, felsic dikes trending roughly east west. [ PRECIS ]

Geologist: S Fumerton

Notes: The two main showing were visited. At the principle showing near the #1 post of claim 619051 (restaked), the stripped area has been centred on an old trench. More recent work has included numerous pop holes blasted after the stripping, scattered over the outcrop but not necessarily following the limited quartz veining. On this site there is an old steam boiler used as a water tank together with some old standard 'A' drill rods. At the second stripped area, near a cabin, there are a few trenches blasted after the stripping.
