[{"type":"text","content":"Murchison Prospecting Identifies Zinc Mineralization and Prospective Volcanic Stratigraphy on May Lake Claims in SaskatchewanTORONTO, ON / ACCESSWIRE / November 13, 2020 / Murchison Minerals Ltd. (\"Murchison\" or the \"Company\") (TSXV:MUR)(OTC PINK:MURMF) is pleased to announce the discovery of new zinc mineralization at its recently acquired May Lake claims in Saskatchewan. The zinc mineralization consists of a grab sample assaying 0.91% zinc, 0.12% copper, 0.08% nickel, and 2.6 g/t silver. The sample was collected as part of the summer prospecting program on the claims acquired to investigate a historic zinc-rich lake sediment sample in Jones Lake which assayed 780 ppm zinc and was collected by the Geologic Survey of Canada in the late 1970's.The newly discovered mineralization was found in shallowly buried pyritic quartz rich bedrock and was located utilizing GDD's beep mat technology. The subcropping zinc mineralization is an indication that the historic lake sediment zinc is locally sourced and signifies that the area is prospective for volcanogenic massive sulphide (VMS) mineralization.Sample location of newly discovered zinc mineralizationGeological investigation of the area revealed a volcanic stratigraphy which consists of basalts, andesites, rhyolites and tuffs. Similar volcanic rocks host the VMS deposits in the Flin Flon camp in Manitoba, many of which are strongly associated to rhyolite bodies. The volcanic stratigraphy is important as it further indicates the area as having high potential to host copper-zinc mineralization.Potential rhyolite observed at Jones LakeHistoric drilling completed in the area by Granges Exploration in 1974 indicated potential VMS type chlorite alteration and drilling in 1968 by Sherritt-Gordon intersected anomalous zinc mineralization. The holes drilled in 1974 by Granges Exploration appear to have correctly identified the volcanic stratigraphy and did note extensive chlorite and epidote alteration but had little sampling and assaying. The presence of sphalerite and VMS style alteration is very encouraging. The historic holes are mostly shallow and likely did not adequately test the area. The area requires more electromagnetic (EM) coverage and additional prospecting. Murchison's one-day reconnaissance prospecting of the area has already returned the highest zinc assays in the history o...
