Nitinat Minerals Corp. is pleased to announce that the work on its 100% owned Jasper Property is underway and is more exciting than ever.
The Jasper Property is located in west-central Vancouver Island, BC, Canada. The Property consists of nine contiguous claims which cover 3978 hectares and is 100% owned and operated by Nitinat Minerals Corporation.
The Jasper Main Grid area is underlain by apparently conformable lithological horizons including an eastern felsic volcanic (dacite or rhyodacite) horizon and a western mafic volcanic (basalt) horizon separated by a central intermediate volcanic horizon. Lithological contacts strike N-S and are offset by cross faults which strike NW-SE. Fifteen polymetallic sulphide zones have been discovered in outcrop over a 2.75 km. strike length within the Main Grid area. Select outcrop sampling of these zones has yielded values up to 20% Lead, 25% Zinc, 15% Copper, 61 g/t Silver and 0.21 g/t Gold from separate samples taken from different zones. A 2.25 km. length by 0.5 km wide polymetallic soil geochemistry anomaly is coincident with the area of polymetallic zones, and roughly coincident with the central intermediate volcanic horizon.
The Jasper Property is hosted in a belt of rocks mapped as upper Triassic to lower Jurassic Bonanza group. The belt trends southeasterly from Nitinat Lake through Gordon River, south of Cowichan Lake. The Bonanza belt is flanked to the west and east by Paleozoic Sicker Group rocks which host the economically important Myra Falls Massive Sulphide district located approximately 120 kilometres to the northwest, and the Lara Massive Sulphide district located approximately 50 kilometres to the east.
A north trending gossanous alteration zone with a strike length greater than four kilometers underlies the Jasper Property from Caycuse Creek in the south to the Nitinat River in the north. The alteration zone is characterized by argillization, silicification and pervasive pyrite flooding. The alteration zone is generally concordant with the foliation and stratigraphy throughout its strike length. The Jasper Main Grid area is partially underlain by the intense alteration zone.
Modeling and 3-D inversion of the 2008 airborne magnetic and electromagnetic data was completed for a portion of the Jasper Property during late 2017. Magnetic inversion established low susceptibility bodies coincident with polymetallic zones surrounded by narrow, vertical high susceptibility pipes. Preliminary electromagnetic inversion established a 2 Layer resistivity model consisting of a thick high resistivity layer from surface to 300-600 m. depth overlying a thin, sub-horizontal to undulating low resistivity (high conductivity) layer. The deep high conductivity layer could represent a sedimentary, replacement, epithermal or metallic sulphide horizon, and has never been tested by drilling.
Two to four deep (750 m.) diamond drill holes are proposed to test the sub-horizontal conductive layer where it is coincident with the area of low magnetic susceptibility and underlies polymetallic soil geochemical anomalies and 14 of 15 known polymetallic mineral occurrences. Downhole EM surveys should be included as part of the drilling program.
A property-wide isopach map of the conductive horizon is being generated by a qualified and experienced geophysicist to better interpret the lateral extent, depth and varying thickness of that horizon for optimization of drilling targets. The exploration permit for the Jasper Property allows for up to 4,000 metres of drilling and is being maintained in good standing.
The selected grades for each element are from different showings. The details are contained in 3 assessment reports 31908, 32906 and 35671 from 2010, 2011 and 2015, all publicly available on http://aris.empr.gov.bc.ca/
