Oct 21, 2014 (Mark Puumala) - The following geological description of the Agar Creek Showing is excerpted from Hart (2000 OFR6037). Exposures in the trenches of the Agar Creek occurrence are highly weathered, obscuring many of the finer textures. The impression is that the white quartz veinlets occupy brittle fractures resulting in a ladder vein pattern within a gray to light brown alteration (Photo 11). The veins have a halo of light brown iron carbonate alteration and disseminated, 1 to 2%, euhedral pyrite. Traces of a green carbonate or mica was observed in one sample. Three samples were collected, one highly veined and two iron carbonate altered wallrock. The assays were all below detection for Au and Ag (samples 287a, b, and c; Table 3). Veining at this occurrence is in a brittle structure in marked contrast to the intensely sheared metavolcanic rocks of the Point and Bluff Showing. As suggested above (see “Structure”), this occurrence is interpreted to be located at a slight flexure in the GLDZ. The appearance of this veining with an iron carbonate alteration and disseminated pyrite halo very closely resembles the style of veining and alteration observed at the Anoki Mine, Larder Lake. The gold in the mine was erratically distributed within and about the veins and could only be outlined by detailed sampling.
Oct 21, 2014 (Mark Puumala) - The following summary of historic exploration results from the Agar Creek Showing is excerpted from Hart (2000 OFR6037). Little Long Lac Mines initially described the occurrence as a silicified and sheared arkose containing small quartz veinlets, pyrite, galena and minor gold (Phelan, 1946). A property visit by the staff of the Resident Geologist’s Office described the occurrence as being a zone displaying progressive shearing from a fresh quartz feldspar porphyry to a sericite schist (Lavigne et al., 1990). Quartz and quartz-carbonate veins form small scale ladder vein structures within the zone, accompanied by carbonate alteration and disseminated 2 to 3 mm euhedral pyrite. The quartz veins are white to dull gray and are commonly less than 15 cm wide, but permeate the trench area. The white quartz was interpreted to represent silicification rather than fracture filling gray quartz. Chloritic wisps delineate the anastomosing cleavage within and subparallel to the shear zone. Lavigne et al. (1990) recorded values of 0.01 to 0.26 oz Au/t reported by C. Bumbu, with a government sample returning 33 ppb Au, 690 ppm Cu and 360 ppm Zn.
