Cohiba Minerals (ASX:CHK) has completed reconnaissance work across the Gathering Lake, Rogers Creek, and Ottertail prospects in Canada, identifying multiple ‘large-scale’ pegmatites.
The $6.63 million market capitalisation company and Dahrouge Consulting started fieldwork on 21 September 2023 at Gathering Lake, which consisted of field mapping and outcrop sampling.
At Gathering Lake, numerous pegmatites were uncovered within meta-sedimentary units and granitic bodies. The pegmatites were sampled for analysis by a commercial laboratory.
Cohiba notes that tourmaline crystals were observed in some of the pegmatites, and this could provide evidence of the compositional evolution of pegmatite-forming melts through magmatic crystallisation and pegmatite melt-host-rock interactions.
At Rogers Creek, Cohiba identified apatite and potentially beryl crystals in the pegmatites in the northeastern part of the prospect, comprising up to 1% based on visual estimates.
Meanwhile, at Ottertail, several granitic pegmatite dykes within a zone consisting of a para-gneissic unit were identified and sampled for analysis.
Many of the pegmatites in the eastern part of Ottertail contained epidote-altered feldspar.
Cohiba Minerals Chief Executive Officer (CEO) Andrew Graham says access to the Big Rock prospect was hampered due to a decommissioned bridge and field conditions, resulting in fieldwork being postponed.
“The field program commenced on 21 September 2023 at Gathering Lake and concluded on 7 October 2023 at the Ottertail prospect.
Multiple large pegmatites were identified and mapped, and samples were collected for analysis via a commercial laboratory. These results will be reported in due course.”
