Rugby Provides Exploration Update on its Gold-Silver Projects in Santa Cruz Province, Argentina
Source: GlobeNewswireVancouver, B.C., May 07, 2024 (GLOBE NEWSWIRE) -- Rugby Resources Ltd., (“Rugby” or the “Company”) (TSX-V: RUG) is pleased to announce the receipt of environmental approval for drilling on the El Zanjon Project (“Zanjon”) south of the Cerro Vanguardia gold-silver mine (AngloGold Ashanti). Drilling water supplies have also been approved. A pre-drilling campaign of ground magnetics and geochemistry can now proceed ahead of a planned 28-hole drilling program.
Zanjon is situated in the Chon Aike Formation of the Deseado Massif, a region of Jurassic age volcanics rocks that host a number of world class epithermal gold-silver systems. The Chon Aike epithermal vein systems are characterized by complex fault systems, some of which are highly mineralized. In the Zanjon area the prospective volcanics are covered by young, flat-lying sediments with an estimated 30-40 metres (“m”) thickness.
Magnetics have proven highly effective in mapping Deseado Massif fault systems, with the Zanjon area being no exception. Rugby’s magnetics has demonstrated that Zanjon covers a network of NW and EW structures that with ionic leach geochemistry are demonstrated to provide significant gold-silver targets.

Zanjon is considered to have excellent potential for discovery of a large, mineralized vein field:
- The Zanjon area was chosen after research identified it as a prime target for the next significant vein field south of the Cerro Vanguardia mine. The selection was based on the Zanjon area being analogous to Cerro Vanguardia where a deflection on a regional north westerly fault zone has provided a network of dilation zones to host the very large array of gold-silver veins. At Zanjon, a regional NW fault set deflects eastward creating similarly favourable structural conditions for the deposition of gold-silver rich solutions in the structurally prepared Chon Aike volcanics (Figure 2).
- Rugby validated the structural model by 320m and 160m spaced ground magnetic surveying.
- Given the sedimentary cover, low-level ionic geochemical techniques were employed to identify target zones within the structures. Figure 3 illustrates an analysis of the 1,740 samples collected using the MDRU Porphyry Index Lateral (MPIx_L)*.
- Prior to drilling a final program of more detailed magnetics will be completed, with line spacings reduced to 80m (or 40m) to provide the detail required for drill collar siting. In-fill geochemical sampling will also be completed.

El Zanjon Drilling Program
A 4,750m drilling program will focus on areas AOI2 and AOI3, comprising 28 holes with an average depth of 170m to test 15 targets. The approximate drill locations are depicted in Figure 4. The program is planned to comprise 3,655m of diamond drilling and 1,095m of tricone precollar. The precollar depths are estimated at 40 to 60m to reach the Jurassic paleosurface.

The Venidero Gold-Silver Project
Rugby's Venidero project covers 7,996 hectares in the western area of the Deseado Massif, Argentina. It is approximately 60 kilometres south of Newmont's Cerro Negro gold mine, a large system of epithermal gold-silver veins with reserves of 2.56 million ounces of gold at a grade of 8.89 grams per tonne (2021 Newmont Reserves Release).

Venidero hosts the north-south striking gold-bearing Gorgonzola vein. Drilling has yet to be conducted. Recent mapping has opened up the potential of Venidero with the discovery of 14 areas characterized by low temperature silica vein material with blocks measuring up to a meter in diameter (Figure 6). These silica zones are up to 100m in length. The vein material was not sampled due to not having the appropriate equipment during the mapping campaign. The silica appears to be associated with interpreted structures on magnetic lows, a promising environment for ore deposition. Detailed mapping and geochemical sampling of the new areas will be undertaken in Q4 2024. A 132-line km ground magnetic survey was also completed on the southern grid.

About Rugby
Rugby is an exploration company conducting “discovery stage” exploration on targets in Argentina, Australia, Chile, Colombia and the Philippines. The Company’s focus has been the potential discovery of a high-grade copper-molybdenum-gold porphyry at Cobrasco, Colombia and a copper-gold-iron oxide system at Mantau, Chile. In Argentina, the focus is on high grade gold-silver discoveries near existing mines in the prolifically mineralized Santa Cruz Province.
The Company continues to make progress in securing a potential partner to advance its Cobrasco project in Colombia.
Rugby 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.
