PROJECTS
The project hosts low-sulphidation epithermal-style gold-silver in quartz stockworks, veins and hydrothermal breccias controlled by the regional north-northwest trend. Mineralization is hosted by intermediate volcanics, and pre-mineral, dacite-rhyodacite dykes emplaced along fractures aligned to the regional trend. The structures are laterally extensive and often conspicuous due to the erosion-resistant nature of the coincident dykes. Work to date has identified anomalous gold and silver mineralization over many kilometres. Historical underground workings indicate that mineralized zones within dilationary jogs or bends along the target structures can achieve true widths of up to 20m.
Silver Viper Minerals’ property originally comprised 35,598 hectares in six mineral concessions collectively referred to as La Virginia Gold-Silver Project. In order to reduce claim maintenance costs, the Company completed a project-wide reconnaissance campaign to reduce the area of the large claims, allowing the company to focus on exploration of the recognized mineralized trend. The Company now owns 6,882 hectares (100% ownership), which is fully permitted until 2027.
The project is remote, and a field camp is in place on the property. Exploration work began with a regional targeting and reconnaissance survey and progressed to drill testing in September 2018. Recent exploration work has included two phases of diamond drill testing. Phase I drilling, designed as a first pass test along known mineralized trends and potential parallel structures, was completed in December 2018 and totaled 20 holes for 4,753 metres. Phase II focused on target areas north of the historical exploration areas, notably the El Rubi discovery area, and added 20 more holes for 6,955metres. Total meterage completed by Silver Viper at the pause in drilling totals 11,708 metres in 40 holes.
The El rubi discovery is 2.5 km north of the historic Pan American Silver & Minefinders area. It is structurally controlled by NNW trend. Its structural interpretation is fault-offset continuation of Las Huatas / La Virginia trend. Exploration activity shows multiple mineralized showings being advanced along strike.
The project has seen small scale exploitation of gold-silver bearing veins and breccias, the last period of this type of work was in the 1970s, where some small-scale underground mining was completed at several locations over the property. The historical work is estimated at some 210m of development. No production records are available but the bulk of work was completed at two locations, the still accessible La Virginia and Con Virginia workings.
Following almost three decades of inactivity, the locations was rediscovered by Minefinders Corporation Ltd staff during a regional reconnaissance program in 2007. The property was acquired and fieldwork undertaken in the form of surface sampling and mapping. Exploration work began in earnest between 2010 and 2013 during which time Minefinders and later Pan American Silver completed 188 diamond drill holes for a total of 52,635m.
Exploration was continuous during the acquisition of Minefinders by Pan American Silver Corp in 2012. Pan American continued with the drilling until early 2013 and conducted some reconnaissance work over the exploration claims before pausing.
Upon completion of work in early 2013, Pan American Silver mothballed the project. Subsequent years saw the option agreement terminated and the central claims El Rubi, El Rubi Frac 1 and Esperanza returned to original claim owners. Silver Viper has now restored the property into a single group of claims and has embarked upon an exploration program which includes definition and extension of known mineralized zones as well as evaluation and testing of regional targets.
2018 saw the re-commencement of work on La Virginia, with a focus on testing additional, outlying targets not previously tested by the intense work of Minefinders and Pan American Silver.
Silver Viper’s maiden diamond drilling program at La Virginia began in late September 2018 and continued until December 2018 for a total of 4,753 metres in twenty holes. Follow up drilling ran from late 2019 to March 2020 and added twenty additional holes for 6955 metres.
Phase II exploration focused primarily on the El Rubi discovery area and has now in 2026, expanded to El Molino, Los Cantiles, Macho Libre and El Oriental.
The first phase 5000 m program will be split between El Rubi and El Molino. The 25,000 m drill program focus will be informed by first 5000 m, with the goal of making new discoveries at El Rubi, El Oriental, Macho Libre, or other targets of interest; and expansion drilling on potential discovery at El Molino, depending on results of the preceding 5000 m program.
La Virginia is situated in basin and range topography, the uplifted rocks of the escarpment expose intermediate volcanics, andesites, of the Lower Volcanic Sequence, common within the Sierra Madre. Rhyolite tuffs of the upper Volcanic Sequence cap some of the mountains in the target area, increasing frequency and thickness to the east.
Mineralization is characterized by epithermal style gold-silver in quartz stockworks, veins and hydrothermal breccias controlled by regional north-northwest trending structures. Veining/silicification is typically found within Lower Volcanic Sequence intermediate volcanics as well as dacite (to rhyodacite) dykes. The dykes pre-date mineralization and exploit the same regional structures, often forming low, relatively erosion resistant ridges which are conspicuous and extensive. Gold-silver mineralization is controlled by the north-northwest regional trend and anomalous geochemical results have been returned from these structures south to north for the length of the property.
Historical mining activities in the core claims, evidenced by several underground workings, are developed on zones of increased silica alteration and veining. The largest historical workings, “La Virginia” and “Con Virginia” are still accessible and host mineralization ranging between one metre to greater than twenty metres in thickness.

The mineral resource model was estimated using drilling data generated by Silver Viper and previous operators, and includes two main areas along the mineralized trend, “El Rubi” and “Virginia”. El Rubi resource represents the focus of Silver Viper’s drilling efforts since 2019 and includes indicated and inferred categories. The Inferred category Virginia resource includes four deposits along a roughly 3.2 kilometres stretch of the mineralized trend.
The Mineral Resources for the La Virginia Project are reported in accordance with the guidelines of the Canadian Securities Administrators National Instrument 43-101; and have been estimated in conformity with generally accepted CIM “Estimation and Mineral Resource and Mineral Reserve Best Practices” guidelines. It should be noted that mineral resources are not mineral reserves and do not have demonstrated economic viability.
