Vancouver, B.C., Oct. 31, 2022 (GLOBE NEWSWIRE) -- The Board of Directors of Rugby Resources Ltd. (“Rugby” or the “Company”) (TSX-V: RUG) is pleased to announce the discovery of high grade copper mineralisation over significant intervals in its first test of the Cobrasco porphyry in Western Colombia. Cobrasco has not been previously tested by Rugby or any other operator.

Highlights

  • CDH001 completed to a total depth 1,036 metres (“m”) intersected 82m of 1.00% CuEq¹ within a broader interval of 808m of 0.46% CuEq¹ from 184m

  • Potassic alteration within quartz diorite porphyry with primary bornite (68% copper) dominant with lesser chalcopyrite (33% copper), very minor molybdenite and pyrite

  • CDH002 currently at 781m

Rugby’s Chairman, Yale Simpson, stated “Rugby is excited to announce the discovery of a copper porphyry in only the first test of the Cobrasco mineral system. Such significant copper intercepts indicate the system is robust and worthy of significant ongoing exploration. The second test, CDH002 is in progress.

“Rugby’s goal is to discover and evaluate metals required globally as countries transition to a more sustainable future. In pursuing that goal we are conducting operations with local participation and the highest environmental standards I have seen in the exploration industry. Rugby is placing an equal emphasis on the management of our social/environmental programs and on our technical program.”

CDH001 was oriented in a south westerly direction at a shallow inclination (average -42 degrees) across the northern portion of the large surface footprint of the Cobrasco porphyry. The mineralised porphyry shows encouraging potassic alteration within quartz diorite porphyry generally in association with the better copper grades. Retrograde sericite alteration overprinting is evident. It is anticipated that even higher copper grades may be present at depth below the sericite overprint zone. A deeper test is planned to assess this possibility. Assay results are summarized in Table 1.

CDH002 is inclined at -70 degrees to test the mineralised zone intersected in CDH001 some 300m to 400m deeper in the system. It is currently at a depth of 781m, with a target depth of 1,200m. Initial assay results are expected in early December.

Technical Information and Quality Control & Quality Assurance

Rugby’s sampling techniques and data management are conducted to industry standards. Sample assay results have been independently monitored through a quality control/quality assurance (“QA/QC”) program that includes the insertion of blind certified reference materials (standards), blanks and duplicate samples. Logging and sampling were completed at a secured Company facility located in Quibdo, Colombia. Drill core was cut in half on site and samples were securely transported to ALS Minerals (ALS) facility in Medellin, Colombia where all sample preparation was completed. Sample pulps were forwarded to ALS’ regional hub in Lima, Peru where all analytical work was conducted. All samples are assayed for gold by fire assay of a 30-gram charge with AAS finish (method Au-AA23) and 48 element ultra-trace level detection by four-acid digestion with ICP-AES/ ICP-MS finish (method ME-MS61). Over-limits or ore grade elements were assayed by four-acid digestion with ICP-AES finish (method OG62).

ALS is independent of Rugby and is certified and ISO 9001 & 17025, by the IQNet and “Standards Council of Canada”, respectively. The Company is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the reported data.

1 Copper Equivalent (“CuEq”) grades were calculated using the following formula: CuEq % = Copper (%) + (Molybdenum (%) x 5). The calculations assume 100% metallurgical recovery and are indicative of the gross in-situ metal value assuming metal prices of USD $3.50/lb Cu and USD $20.00/lb Mo.

About Rugby

Rugby Resources Ltd. is an exploration company conducting “discovery stage” exploration on a portfolio of copper, gold and silver targets in Colombia, Argentina and Chile. The Colombian Cobrasco project is located in the western cordillera belt which hosts large scale copper molybdenum mines in Chile, Peru, and Panama (and more recent significant projects discovered in Ecuador). This belt has not been subjected to modern exploration in Colombia. Rugby looks to advance the Cobrasco project to demonstrate the economic potential of a major discovery for Colombia. The discovery of significant copper resources is essential for the world to move from fossil fuels to advanced “green” electrification.

The Company benefits from the experience of its directors and management, a team that has either been directly responsible for world-class mineral discoveries or has been part of the management teams responsible for such discoveries. Prior companies under their management included Exeter Resource Corporation and Extorre Gold Mines Limited, which held significant projects in South America. These companies were taken over by Goldcorp (Newmont) and Yamana respectively.
