Point Location Description: Trenches.
Location Method: Conversion from MDI
Access Description: The occurrence is located in northeastern Vincent Township. The claims lie 13 km west southwest of Jellicoe and 0.8 km south of the Blackwater River and Canadian National Railway tracks. A bush road parallels the south side of the tracks from Kyro's (west) Road. In low water conditions, a four wheel drive vehicle can be driven through the river to an area north of the main showings. Access may be realized by boat across Nezah Lake and along trails/claim lines.
1983: Neil and Mark Maki staked a group of claims to the east of the adjoining Pichette Occurrence. 1984: Quinterra Resources Limited optioned the property (28 claims).

Dec 07, 2005 (B Nelson) - The Maki East Occurrence is hosted in the Southern Metavolcanic Sub-belt of the Wabigoon Sub-province. Basalt and mafic to intermediate tuffs, minor mafic to felsic intrusions, with chemical and minor associated interflow sedimentary rocks are present in the sub-belt. Foliation is generally 070 degrees to east-trending. Rocks dip steeply to the north to vertically. Rocks are metamorphosed to greenschist grade. The Maki East Occurrence is underlain by mafic metavolcanics (basalts and tuffs) hosting chemical metasediments. Gold mineralization is associated with chemical metasediments (ironstones). These ironstones are banded and consist of recrystallized chert, magnetite or hematite (some specular) and iron amphiboles (including grunerite and hornblende). At least four ironstone units striking 260 degrees have been located by stripping. Two of the units are subparallel, approximately 10 m apart, and are separated by sheared to massive, silicified, intermediate volcanic rocks. Mafic tuffaceous rocks, also silicified, form the north contact of the most northerly ironstone. Gold is associated with replacement pyrite and arsenopyrite in the ironstone. Minor narrow quartz veins occur with erratic sulphides.

Dec 07, 2005 (B Nelson) - Gold is associated with replacement pyrite and arsenopyrite in the ironstone. Minor narrow quartz veins occur with erratic sulphides. 8 samples taken in 1983 all returned assay values of <0.01 oz/ton Au. Of the 21 samples taken in 1984, the best results were values of 530 ppm As, 1.1 ppm Sb, and 1690 ppm Au.
