Lara now owns 100% of the Homestead discovery, subject to a 2% NSR royalty payable on any production (Lara retains the right to purchase 50% of this royalty for a cash payment of US$2 million). The Planalto Copper Project covers volcano-sedimentary sequences and intrusives of early Proterozoic-age with IOCG-type mineralization, located near Vale’s Sossego mine and Cristalino deposit and BHP’s Pedra Branca mine and Antas mill, in the Carajás Mineral Province of northern Brazil. Gold was determined by fire assay fusion and an ICP-AES finish on a 30-gram charge. The pulps were subjected to multi-acid digestion with copper and 47 other elements were determined by ICP-MS. The sample pulps were then dispatched to the ALS laboratory in Lima for analysis. The drill core samples were delivered by company personnel to the ALS preparation laboratory located in Parauapebas, 65 km to the north from the Project, where they were crushed and pulverized. Blank, duplicate core or certified gold and copper reference materials were inserted at approximately every 10th sample. Sample intervals for the drill core were mostly maintained at about 2m with some variation in the weathered saprolite zones and at times guided by the degree of copper mineralization. Samples from the first two holes (23-001 and 23-002) are already being processed by ALS in Parauapebas.ĭrillhole collars, Sampling methodology, Chain of Custody, Quality Assurance and Quality Control DrillholeĪll the drill core is cut and sampled under the supervision of the company´s Vice President Exploration and the chain of custody of the drill core from the Project area to the Company´s sample preparation facility in Canãa dos Carajás was continuously monitored. Seven holes have been completed to date for approximately 3000m of the planned 10,000m drill program scheduled to be completed by the end of August to test the extensions of the Cupuzeiro and Homestead targets. Link to Figure 1 – Cupuzeiro Drillhole Map The intercepts reported are down hole intervals and additional offset holes are required to better define the trend and attitude of the mineralized envelope and the higher-grade zones within it. No allowance has been made for metallurgical recoveries of either copper or gold. Notes: Copper equivalent values in this table were calculated using a copper price of US$3.40/lb and a gold price of US$1,800/oz, with only sulphide values, a minimum interval width of four metres and a maximum of six metres of internal waste considered. Table 1: Composite copper and gold analyses for follow-up drill testing completed in Q4-2022 & Q1-2023 on the Cupuzeiro target, Planalto Copper Project, Para State, Brazil. These new results summarized in Table 1 below, indicate that the previously reported higher-grade copper mineralized zones are now interpreted to extend to more than 300m vertically below the surface and most of the zones are still open to depth. (“Lara”) is pleased to report the results of six follow-up drill holes to the immediate north eastern side of the Cupuzeiro target, two of which, holes 22-011 and 22-014, gave intersections of 47.22m at 0.652% copper equivalent and 41.51m at 0.737% copper equivalent, respectively, below the zone of high grade intersections reported previously for the Cupuzeiro target (see news releases of and September 13, 2022).
