Vancouver, British Columbia--(Newsfile Corp. - September 13, 2022) - Lara Exploration Ltd. (TSXV: LRA) ("Lara"), Lara is pleased to report the results of seven follow-up drill holes from the Cupuzeiro target, the best of which, 22-007, made a sulphide-copper intersection of 380.79 metres from near surface, averaging 0.575% Cu equivalent, including two zones of higher-grade mineralization: 78.81 metres grading 1.083% Cu from 17.8 metres, and 40.4 m at 1.308% Cu from 121.68 metres downhole.

Drilling on the Cupuzeiro target from late 2021 (see news release of May 16, 2022) intercepted wide zones of higher-grade copper mineralization (notably hole 21-002 with an intercept of 341.30 metres at 0.65% copper equivalent and hole 21-005 which intercepted 339.75 metres at 0.53% copper equivalent). Hole 22-007 from this follow-up program, drilled diagonally across this zone on a northeast azimuth, confirmed the presence of a significant core of high-grade copper mineralization, over more than 100 metres in strike length, on a north-south trend in this target.

Four holes testing the north extension of this core zone: 22-006, 22-008, 22-009 and 22-010, indicate that significant, albeit lower grade mineralization, is still present for up to 300 metres to the north and is still open up-dip, to the north and at depth. Two holes, 22-004 and 22-005, drilled to test the west extension to the high-grade core zone, also made significant copper intersections.

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. No allowance has been made for metallurgical recoveries of either copper or gold. 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.

Additional drill testing at the Homestead Copper Target

Three drill holes: 22-001, 22-002 and 22-003, were also completed in early 2022 to test IP (Induced Polarization) anomalies to the south, east and west respectively, testing for extensions of the Homestead Target (See previous news releases of July 23, 2019, and April 20, 2020).

Hole 22-001 intersected 27.67 metres at 0.417% Cu at considerable depth down hole (362.03 to 389.70 m) indicating the there is potential to find extensions up-dip and southwards of the Homestead mineralization. No significant copper mineralization was intersected in hole 22-002 located to the east of Homestead and only thin high grade vein intervals of less than 1 metre were intersected in the hole 22-003 located out to the west of Homestead.

All 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. 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. Blank, duplicate core or certified gold and copper reference materials were inserted at approximately every 10th sample.

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. The sample pulps were then dispatched to the ALS laboratory in Lima for analysis. The pulps were subjected to multi-acid digestion with copper and 47 other elements were determined by ICP-MS. Gold was determined by fire assay fusion and an ICP-AES finish on a 30-gram charge.

About the Planalto Project:

The Planalto Copper Project covers meta-volcano-sedimentary sequences and intrusives of early Proterozoic-age with IOCG-type mineralization, located near Vale's Sossego mine and Cristalino deposit and Oz Minerals' Pedra Branca mine, in the Carajás Mineral Province of northern Brazil. Lara now owns 100% of the main Planalto Project and 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). Lara has further options to acquire outright two adjacent licenses, covering northward strike extensions to the Homestead mineralization, from Mineração Tariana and Mineração Zaspir (see news releases of January 11 and March 15, 2021, for details). Lara has a staged earn-in agreement with a subsidiary of Capstone Copper Corp., (see Company news release of February 4, 2019, for details), whereby Capstone can earn up to a 70% in the Project by funding exploration, feasibility studies and electing to finance, build and manage a commercial mining operation, with Lara repaying its pro-rata share of the production financing out of cash flow.
