Vancouver, B.C., May 31, 2022 (GLOBE NEWSWIRE) — Rugby Mining Limited (“Rugby” or the “Company”) (TSX-V: RUG) is pleased to report on recent exploration progress on its projects.
- The El Zanjon gold-silver project, Argentina is one step closer to drilling. Assays received for 468 soil samples show gold-silver and pathfinder anomalies coincident with +10 new structural lineaments.
- At Cobrasco, Colombia environmental studies performed. Other investigations included topographic, geochemical and geophysical surveys.
- At Salvadora, Chile field work included geologic mapping and drill target assessments. Three additional targets identified along the seven-kilometre-long alteration feature.
El Zanjon Project, Santa Cruz Province, Argentina
The Company is targeting high grade gold silver epithermal veins in the Deseado Massif, host to a number of exceptional epithermal deposits. Rugby’s project is 30 kms southeast of Cerro Vanguardia in an area previously unexplored due to 50 to 100 meters (“m”) of sedimentary cover. The terrain is interpreted to be a direct continuation of the Cerro Vanguardia mine host rocks.
Work by Rugby began 2 years ago with regional magnetic surveys, a tool to map the subsurface volcanic terrain. That work identified northwest trending magnetic features (lows) (Figure 1), several of which bisect a prominent, 10 km wide circular magnetic high.

Further ground magnetic surveying identified east-west structures considered ideal for potentially hosting high grade gold silver mineralisation. To confirm that potential 468 ionic leach geochemical samples were taken at 320 m intervals along the prospective structures. Results from that sampling have now been received (Figure 2) showing significant gold anomalies with elevated values of silver, arsenic and molybdenum.
The broad distribution of the anomalies and their close association with structures suggests the El Zanjon project has captured a potential mineral field, the size of which is comparable to Cerro Moro and Cerro Vanguardia. The sample density will now be closed down to 160 m spacings after which we will further close in the ground magnetics.

Yale Simpson, Rugby Chairman stated, “The more work we do on El Zanjon the more promising the project becomes. Identifying targets in both northwest and east-west linears is just what we wanted to see, given our experience in this region. The junctions of the two linear sets are particularly favourable for ore deposition.”
“Given that there is no outcrop we still need to close in the magnetic and geochemical surveying through 2022. That said, we have every reason to expect that those results will continue to be as compelling as what we have seen to date.”
Cobrasco Copper Project, Colombia
Field work has commenced on the Cobrasco Project, including environmental, orientation geophysics and both soil and rock sampling. The environmental work was a continuation of previous assessments that included both soil and vegetation categorisation work. Specifically which areas have limited forest cover and relatively good access. This work was conducted by recognised environmental experts.
The auger soil geochemical program has delineated a significant copper-molybdenum anomaly that remains open in two directions (Figures 3 and 4). The figures graphically illustrate very elevated copper-molybdenum values in soils. Rock chip sampling results are awaited.

Geological mapping identified the phyllic zone of a copper-molybdenum porphyry. Outcrop including zones of intense quartz-pyrite-bornite-chalcocite-molybdenite stockwork veining was located in a number of creek exposures that were channel sampled with results pending (Figure 5).

Magnetization Vector Inversion (MVI) modelling from Rugby’s airborne magnetic survey shows a significant body of elevated magnetics from 300 m to 1500 m below surface with dimensions up to 800 m x 1,200 m, which may represent the potassic alteration zone in the mineralised intrusive (Figure 7).

A trial 200 m dipole-dipole Induced Polarisation survey was run over the central part of the porphyry system (Figure 7).

Salvadora Copper-Silver Project, Chile
Field work including geologic mapping and drill planning continued through to the onset of the southern winter. The southern prospect named Heliodora is considered the most favourable drill target. The vein system is potentially a 50 m wide zone within a north trending structure. The strike of the structure has been modified by a north westerly structure. Three additional drill targets were identified along the 7 km long alteration feature.
Yale Simpson, Rugby Chairman stated, “We are concerned about the current heightened state of political uncertainty and its potential effect on copper and lithium mining in Chile. The effect of the implementation of any negative proposals would be to curtail new project development whether it be mining or exploration. We will therefore defer drilling at Salvadora until we see clarity of the matter.”
Paul Joyce, Rugby’s Chief Operating Officer, Director and a “qualified person” (“QP”) within the definition of that term in National Instrument 43-101, Standards of Disclosure for Mineral Projects, has verified the technical information that forms the basis for this news release.
Rugby is an exploration company conducting “discovery stage” exploration on targets in Colombia, Chile, and Argentina. The Company’s focus is the potential discovery of a high-grade copper molybdenum porphyry system at Cobrasco in Colombia. Rugby is also working on a possible discovery of high-grade silver-copper-gold at the Salvadora Project in Central Chile’s El Indio Gold Belt as well as a gold-silver project in the prolific mineralized belt in Santa Cruz Province, Argentina. Rugby also controls a large portfolio of gold projects and/or applications in Colombia which are moving through the process for title grant. We intend to move to expedite this process where possible.
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 have 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.
