Vancouver, British Columbia--(Newsfile Corp. - January 29, 2024) - Lara Exploration Ltd. (TSXV: LRA) ("Lara") is pleased to provide an update on work at its Planalto Copper Project in Brazil. Q4-2023 saw the completion of the 2023 drill program of 9,100m, linking the Homestead and Cupuzeiro discoveries into a single body of mineralization, with Final Exploration Reports then filed with the National Mining Agency ("ANM") on the two northern licenses, defining mineral resources to Brazilian standards for the Cupuzeiro mineralization and the Gap Zone linking it to the original Homestead discovery. The Company has now started work on resource estimates and plans to undertake further technical and environmental studies on the combined Homestead and Cupuzeiro target in the coming months.
During Q4-2023 the Company also received results of the preliminary metallurgical testwork for the Cupuzeiro mineralization, undertaken on a master composite with a head grade of 0.46% Cu, a low-grade composite with 0.34% Cu and a high-grade composite with 0.85% Cu (all with minor amounts of gold). QUEMSCAN analysis showed the dominant sulphide mineral to be chalcopyrite, though unlike Homestead, this portion of the body also carries some pyrite. The primary gangue minerals are quartz, feldspar, biotite, and chlorite, with a notable percentage increase in the micas relative to quartz and feldspar in the higher-grade sample. Copper recoveries of 88-92% were reported depending on grind size, with a similar performance for all three composites. see & read more on
