RUGBY RESOURCES LTD. PROVIDES YEAR END EXPLORATION UPDATE

Vancouver, B.C., Dec. 12, 2022 (GLOBE NEWSWIRE) -- The Board of Directors of Rugby Resources Ltd. (“Rugby” or the “Company”) (TSX-V: RUG) is pleased to provide an update on the Company’s exploration projects. Current activity is focused on its porphyry copper discovery at Cobrasco, in Colombia.

Cobrasco Copper - Molybdenum Project

Rugby is the first company to drill test the Cobrasco copper-molybdenum porphyry system in Colombia. Drilling was initiated in August with the third drill hole currently underway.

A second hole, CDH002 has been completed and assays are awaited. It was targeted on the basis of surface geochemistry and positive results from the first drill hole CDH001, 82 metres (“m”) at 1.00% CuEq¹ within a broader interval of 808m of 0.46% CuEq¹ (see News Release dated October 31, 2022). CDH002 was drilled 400m south of CDH001 (see Figure 1 below) and as anticipated, it intersected a wide interval of mineralised diorite porphyry. However, it was abandoned at 946.1m in a fault zone, some 300m short of its planned target depth.  Full assays are anticipated within 6-8 weeks.

CDH003 is in progress, utilizing the same drill platform as CDH002. It is being drilled in a northerly direction to test the higher grade mineralised upper part of CDH001 at a greater depth. CDH003 will also be extended to the north of CDH001 below a zone of anomalous soil copper-molybdenum geochemistry. Collar locations are shown on Table 1.

Rugby is also conducting comprehensive geological mapping and geochemical surveys to identify other porphyry copper targets within the Cobrasco intrusive complex. During the current program, 433 soil auger samples were collected on an 80m x 100m spaced grid and a further 144 samples are planned before year end. Although only partial assays are available, the data using the MDRU Porphyry Index3 (MPIx) developed by the Mineral Deposit Research Unit at the University of British Columbia, highlights multiple areas warranting future exploration and follow-up drilling (Figure 2).

Rugby’s Cobrasco Project Manager, Francisco Montes, stated “ CDH002 intersected disseminated copper-molybdenummineralisationbeginning just below the drill collar. Metal veining was increasing in the lower sections of the hole. The porphyry targeting index (MPIx) suggests the potassic core may be more extensive below the bottom of the drill hole. It is unfortunate that an unanticipated fault zone prevented us from testing thehigh gradezone intersected in CDH001 at greater depth. It is very encouraging however thatmineralisationextends essentially all the way down the hole.  As assays typically take 6 to 8 weeks, results from CDH002 are expectedin January”.

“A comprehensive field program is underway comprising additional mapping, rock and soil sampling. We are confident this program will define additional targets for follow-up drilling.’’

Appointment of Colombia Country Manager

Rugby recently appointed María Paola Suárez as Country Manager for Colombia. María Paola is a lawyer with 17 years of experience in both the private and public sectors.  

She served as Deputy Minister of Political Relations (2021-2022) and in various other senior government roles. She led important national processes such as the 2019-2022 legislative agenda and elections for both the Congress and the Presidency. Her work in the public sector included the promotion and development of relationship strategies with different governmental, trade associations and community groups. That experience provides her the insight for her role as Country Manager. In particular, María Paola will focus on ESG and government relationships. 

Environment and Community

Rugby places a high priority on good environmental practices to ensure minimal impact from its activities. It has an ongoing site rehabilitation program including an active nursery program to safeguard the integrity of the ecosystem on the project. Rugby also has a prior consultation agreement (“CP”) with the local Cocomacia community which provides for access to the project area and various ongoing social development programs to benefit the community. The Company is actively engaged with the Cocomacia community working on new initiatives and programs to be funded in the coming months.

Chile - Salvadora Project

Following the Company’s recent discovery at Cobrasco, the Board has determined that the Company’s focus must remain on the delineation of the Cobrasco discovery. Consequently, the Company will terminate its option on the Salvadora Project in Chile. Investment uncertainties in that country, high holding costs and the limited scope of the target relative to Cobrasco make the decision an unfortunate but obvious one. 

Argentina - El Zanjon and Venidero Projects

The El Zanjon epithermal gold-silver project is located south of the Cerro Vanguardia Mine in Argentina, [Resource - 2.11 million ounces gold and 79 million ounces silver (AngloGold Ashanti 2021 Report4)]. Surface sampling to date has defined an extensive distribution of gold and silver along lineaments and at the intersection of major NW and E-W fault systems. The structural targets are covered by up to 80 m of overburden. Additional sample results are awaited (see Figure 3) to be followed by drill target ranking. Drilling is planned for 2023 following the usual government permitting processes.

At Venidero, ground magnetic surveying was conducted over the vein system and a sinter zone to define target areas for follow-up soil and rock geochemistry. A number of epithermal rock samples from new vein occurrences were collected with assays now awaited.

Philippines - Motherlode copper-gold Project

The Motherlode Project is a large-scale copper-gold-molybdenum porphyry system in the Philippines. Further drilling is definitely warranted but the project remains on care and maintenance due to our priorities elsewhere.

About Rugby 

Rugby Resources Limited 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 new copper opportunities is essential for the mining industry to supply the copper necessary to transition from fossil fuels to advanced 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.
