Exploration History

1944: Kega Gold -Diamond drilling. 1952: Peteque Mines - trenching, sampling and diamond drilling. 1956-57: Senet Copper Mines - Geological mapping and geophysical surveys. 1969-70: Minorex - Prospecting and geophysical surveys. 1996-97: Wolfden Resources - Prospecting, sampling, geological mapping and geophysical surveys. 2014: GoldenShare completed a lithogeochemical sampling program to evaluate historical showings and to help define types of alteration associated with the mineralization.

Geology Comments

Nov 15, 2016 (Andrew Tims) - The trench has a direction of approximately 50°, a length of 23 m and an average depth of 1 m. The drill casing, located at the SW end of the trench, has a direction of 40° and a dip of -50°.The rocks hosting the trench are gossan-stained, grey-green, sulphide-rich chert which is thickly laminated to very thinly bedded. Two semi-massive sulfide units are separated by a fine grained andesite (field name) a few metre wide. No significant assay were generated by Goldnshare sampling.

Lithology

Lithology Comments

Nov 20, 2014 (Mark Puumala) - The McCloskey showing is reported by Atkinson et al. (1990) to be a 3 m by 3 m trench excavated on gossan-stained, grey-green, sulphide-rich chert that is thickly laminated to very thinly bedded. Mineralization in this trench is reported to consist of disseminated pyrrhotite and pyrite. Lithologies noted in the general area of the showing by Atkinson et al. (1990) are dominated by mafic metavolcanics with some schistose metasediments also reported. A foliation/stratigraphic contact strike orientation of 130 was reported in the area by Atkinson et al. (1990) Ayres (1972) reported that the mineralized chert horizon is up to 30 m thick and contains disseminations of pyrrhotite, narrow veinlets of chalcopyrite and rare sphalerite. Downie (1996) described the mineralized horizon as a modest unit of short strike length that consists of chert, silicified argillite, and argillite (or very fine-grained volcanic debris). Mineralization was described as consisting of pyrrhotite, magnetite, pyrite and chalcopyrite in decreasing order of abundance. Parker (1999) noted that the mineralized chert horizon is underlain by mafic metavolcanic flows that have been altered to a calc-silicate assemblage of quartz, epidote, diopside, garnet and calcite. The alteration increases in intensity toward the chert horizon and has been interpreted by Parker (1999) to represent synvolcanic alteration, suggesting that this sulphide occurrence is of volcanogenic origin.

Mineralization

Mineralization Comments

Nov 20, 2014 (Mark Puumala) - The most notable assays reported from this showing include 2.2% Zn, 0.32% Cu and 0.72 oz/ton Ag from grab samples collected by Ayres (1972). Samples collected by Atkinson et al. (1990) did not return any significant results. The most notable sample assay results reported from a 1996 exploration program carried out by Wolfden Resources (Downie 1996) included 2428 ppm Cu and 578 ppm Ni .

Jul 31, 2019 (Therese Pettigrew) - Samples collected during the 2014 prospecting program returned results of up to 0.12% Cu, 0.49% Zn, 0.03 ppm Au, 0.6 ppm Ag, and 2.60 ppm As (Assessment report 20000008320). Chalcopyrite and pyrite are also recorded in quartz porphyry between multiple auriferous quartz veins on KRL 36756 (the Springer Showing), approximately 244 m southeast of the main showing (SMDR 00508).
