Point Location Description: Centre of trench with exposure of banded iron formation.
Location Method: Field Visit with GPS
Access Description: Showing can be reached by walking north along an old logging road off Highway 101 at a point 2.4 km east of Scorch Creek along the highway. The occurrence is approximately 1.4 km up this road and lies about 6 m to the east.
1970 Staked by Dan Rochon of Timmins who made the discovery and optioned to United Macfie Mines Ltd.(43.5% owned by Kam Kotia Mines Ltd.). During the later part of 1970 and early 1971, Mid-North Engineering Services Ltd. completed a ground magnetometer and electromagnetic survey for United Macfie Mines Ltd. over the claim group that included the showing. Sampling of the trenches by United Macfie Mines disclosed a weighted sample of 0.30% Cu over a width of 8.2m. Three holes totalling 393m were drilled by the company and encountered disseminated sulphides and stringers over varying widths. Sulphides reported included pyrite, pyrrhotite, minor chalcopyrite and sphalerite.

Dec 07, 2005 (K Houle) - Well banded becoming coarser grained to the north perpendicular to the strike. Iron Formation consists of alternating bands of quartz, sulphides, magnetite and amphibole, and intercalations of what may be fine sandstone. The unit has been concordantly intruded by a pink, medium grained porphyritic granite and blue-grey quartz diorite.

Dec 07, 2005 (K Houle) - Sulphide content is variable from trace to 60% and includes pyrite, pyrrhotite and minor chalcopyrite. Pyrite and pyrrhotite appear to be concentrated along margins of the more siliceous Iron Formation layers. Chalcopyrite occurs as disseminated grains and irregular splashes. Chalcopyrite varies from trace to about 1%. A polished section prepared from a pyrrhotite and chalcopyrite stringer showed that the chalcopyrite is intergranular to the quartz and occurs in grains composed of in part of pyrrhotite. The chalcopyrite and pyrrhotite are joined along curved, irregular, cuspate boundaries. Several grains of chalcopyrite enclose grains of quartz. (See reference GR157).
Dec 07, 2005 (A Wilson) - Grab samples collected in 1970 returned copper values ranging from 0.06% to 0.44% Cu. A grab sample of semi-massive pyrrhotite and pyrite and tract to disseminated chalcopyrite in iron formation returned values of 0.311% Ni, 0.311% Cu.

Notes: The occupancy measures approximately 6m x 6m with a small trench running down the west side. Outcrop appears well banded with bands of quartz, magnetite and sulphide readily visible. Magnetite bands are generally in the range of 1-2cm while quartz and sulphide bands range from 2-10cm. A quartz diorite dyke was observed intruding the iron formation and is exposed in the trench. Small garnets appear along margins of quartz/sulphide contacts and quartz bands appear recrystallized proximal to the dyke with 1-2mm anhedral grains. Occasional highly chloritized interlayers were observed of sedimentary or volcanic origin. Pyrite and pyrrhotite are the dominant sulphides and appear as semi-massive layers and disseminates generally along margins of sugary quartz layers. Up to 1% chalcopyrite was observed as blebs and fine disseminates generally occurring within the semi massive pyrrhotite. A small exposure of amphibolite schist can be observe at about 15m to the northeast. A drill collar was found at about 25m to the north of the trenched area with UTM coordinates of 17 403565 5342256.
