MURCHISON MINERALS PROVIDES UPDATE ON ITS EXPLORATION PROGRAM AT BRABANT LAKE, SASKATCHEWAN
Murchison Minerals Ltd. has provided an update on its exploration program at Brabant Lake, Sask. The goal of the program was to identify the possible extension of the Brabant-McKenzie volcanic massive sulphide (VMS) deposit and to confirm the potential for discovering additional economic VMS-type mineralization elsewhere on the property. The prospecting program focused on 28 distinct targets chosen amongst the EM conductors identified in the January, 2019, VTEM max airborne survey, which covered approximately 50 per cent of the 324-square-kilometre property holdings.
The geological compilation and interpretation of the exploration data is continuing, with preliminary results suggesting that multiple targets warrant an active exploration drill program.
The work completed by Murchison through the course of the 2019 summer program (May 27 to Aug. 29) comprised prospecting by two teams of two to three geologists or geological assistants. The teams utilized GDD Instrumentation Inc.'s Beep Mat technology.
Beep Mat is a small piece of geophysical equipment that is pulled along the forest floor and creates audible beeps over electrically conductive and/or magnetic minerals such as sulphides. Once the source of the conductivity is located and exposed, the rock is then sampled.
A small gasoline-powered diamond saw and a backpack-sized diamond drill are used to collect suitable amounts of rock to sample. Approximately 294 rock samples were collected and sent for assays.
Multiple conductive zones identified in the January, 2019, VTEM max airborne survey were located by ground prospection. These zones typically required hand trenching through the soil and glacial till to reach bedrock. Trenches were generally 60 centimetres wide and ranged in length from one to 10 metres.
To date, three-dimensional geophysical modelling has been completed on 15 major EM conductors.
Strong EM conductors often concordant with linear swamps/bogs
As part of the summer program, the teams looked at the 2006 to 2008 stored drill core and observed that some of the sphalerite (zinc) mineralization from the drill core was showing signs of severe weathering after approximately 10 years of exposure to the atmosphere. This reinforces the theory that all EM conductors spatially linked to overlying linear bogs/swamps as identified in this prospecting program require drill testing, as they may overlie zinc-rich bodies where weathering may have caused surface depressions.
Copper-bearing mineralization (chalcopyrite) appears much more resistant to weathering and may explain the lack of zinc mineralization observed during this prospecting program where only copper was identified on the surface overlying EM conductors.
A winter soil drill sampling program of the bog mud is planned, as this would quickly indicate the presence of potential zinc-related mineralization.
The geological compilation and interpretation of the exploration data is continuing, with preliminary results suggesting that multiple targets warrant an active exploration drill program. Additional information will be released in the coming weeks.
The foregoing scientific and technical disclosures have been reviewed by Ehsan Salmabadi, professional geoscientist, a qualified person as defined by National Instrument 43-101. Mr. Salmabadi is an independent consultant to Murchison and the Brabant-McKenzie project.
About the Brabant-McKenzie project
The Brabant-McKenzie project is located 175 kilometres northeast of La Ronge, Sask., and approximately three kilometres from the community of Brabant Lake. The area is accessed year-round through provincial Highway 102 and is serviced by grid power. The project comprises one mining lease, which hosts the Brabant-McKenzie VMS deposit, and additional mineral claims totalling 324 square kilometres, which cover approximately 38 kilometres of strike length over favourable geological horizons, multiple known mineralized showings and identified geophysical conductors.
