The Mineral Resource Estimate was completed by independent consultant Dr. Gilles Arseneau P.Geo. of ARSENEAU Consulting Services Inc. The resources were estimated using three-dimensional block model software. All blocks for the Las Huatas, Con Virginia and El Rubi were estimated by ordinary kriging while all other deposits were estimated by ID².  Gold and silver grades within the mineralized domains were estimated in four successive passes for the Las Huatas and El Rubi domains and in a single pass for all other domains. The first pass considered a relatively small search ellipsoid, while the second and third pass search ellipsoids were larger. Pass four was restricted in inform blocks within the deposits, near drill holes that had not been estimated in the three previous passes. Search parameters were generally set to match the correlogram parameters but also designed to capture sufficient data to estimate a grade in the blocks. All grades were capped on 1.5 m composites and ranged from 3 to 15 g/t for gold and 50 to 1,000 g/t for silver.

Mineral resources are reported on a US dollar equivalent cut-off of $US20 (equivalent to a cut-off grade of 0.38 g/t gold OR 28.3 g/t silver) for open pit and $US100 (equivalent to a cut-off grade of 1.88 g/t gold OR 141.4 g/t silver) for underground resources. Reasonable prospect of potential economic extraction is determined by restricting the potentially open pit accessible resource inside a Whittle optimized pit shell based on $US 1,650/oz of gold and $US 22/oz of silver and recoveries of 94% for gold and 90% for silver, overall pit slopes of 50 degrees and a total operating cost of $US 20. Underground reasonable prospect of potential economic extraction is determined by assigning a cut-off of $US 100 to contiguous blocks within a maximum 200 m of the pit surface and a maximum vertical depth of 250 m.

Blocks were classified as indicated mineral resource for the El Rubi deposit if estimated during pass one with at least two drill holes with an average distance of 50 m or during pass two and informed by at least three drill holes within an average distance of less than 100 m. All other estimated blocks were classified as inferred mineral resource.

Geology

The La Virginia Project is an early-stage exploration property situated within a range of mountains in the Sierra Madre Occidental.  The project is largely underlain by rocks of the Lower Volcanic Sequence uplifted and exposed by basin and range faulting.  Mineralized showings occur largely within a kilometre-wide corridor aligned to the north-northwest regional trend defining the range. This corridor, as part of the regional fabric, extends for the length of the project.  The Las Huatas, Con Virginia (includes La Virginia) and El Oriental deposits are located within a 3.0 kilometre portion of the trend. El Rubi is located 2.5 kilometres north of this group of deposits.

Outcropping mineralization on the project was first associated with steeply dipping dacite dykes more resistant to erosion than the country rock, forming low ridges on the hillsides.  At Con Virginia, Las Huatas and El Oriental areas, mineralized veining has been shown to have exploited the same structures as the previously emplaced dykes.  Gold and silver mineralization is often found along the contact zones of said dykes, hosted by andesite wall rock or by the dykes themselves in the form of thin quartz vein stockworks or breccias. Width and tenor of mineralization increase in areas where the hosting structure flexes or within dilationary openings formed by jogs between adjacent faults. This is apparent at both outcrop and project scales.

El Rubi deposit is situated on a mesa roughly 2.5 kilometres in diameter, immediately north of an east-west, fault-controlled canyon which separates and offsets it laterally from the main block hosting the other deposits.  At El Rubi, mineralized structures remain steeply dipping, but demonstrate a north-west strike, indicating a flexure in the north-northwest structural trend.  East-west, north-south and northwest-southeast trending faulting at this location has resulted in the formation of local blocks with vertical or lateral relative movement.

The geology of the El Rubi plateau is represented by a gently eastward-dipping volcanic sequence.  Rhyolitic lapilli tuff on the western side of the mesa is overlain by a mixed volcanic package of andesitic composition.  The andesite package reaches up to 300 m in thickness, and contains weakly porphyritic andesites interbedded with volcaniclastic and agglomeratic andesitic phases, further overlain by uniform feldspar-phyric andesite. 

Mineralization at El Rubi has been intercepted by drilling over a strike length of 500 m and to a vertical depth of 300 m and represents a highly structurally controlled network of steeply dipping quartz veining and vein breccias. Strongest mineralization on the project to date has been encountered along the El Rubi structure, a northwest trending, fault-controlled, often silicified breccia/quartz stockwork zone which dips steeply to the east-northeast.  The El Rubi structure marks the eastern extent of mineralization as modelled in this area.  An additional zone of broad, low to medium grade silver-gold mineralization occupies the footwall of the El Rubi structure, extending up to 200 m west of the El Rubi trend.  In some cases, the mixed andesite package in particular hosts broad zones of fine quartz stringers forming weak stockworks tens of metres in width.  Silver Viper refers to this broad stockwork zone as the "Western Zone" represented by drill intercepts such as those in LV20-245 and LV20-284 (see News Releases dated August 26^th, 2020 and March 1^st, 2021 respectively).

Drilling at El Rubi has targeted the mineralized structures from several orientations, and the use of oriented drill core in four holes has assisted the interpretation used in constructing the model.  

About the Project

La Virginia is located 220 kilometres east-northeast of Hermosillo, Sonora and is prospective for low-sulphidation epithermal precious metal mineralization.  The Property and historical exploration database were acquired by way of option agreements made with two distinct parties. Gold and silver mineralization at La Virginia occurs within breccias, veins and stockworks, hosted primarily by andesitic volcanics, often in close spatial association to, or cross-cutting pre-mineral dacite dykes and controlled by fractures and faults that define the regional structural trend.  Silver Viper's reconnaissance program identified key targets and trends which are of primary interest and subsequently filed strategic reductions in claims to attain the current project surface area of 6,882 hectares.

At the completion of the 2020 phase of work at La Virginia, Silver Viper had completed a total of 100 drill holes for a combined meterage of 27,021 metres across the project. Exploration drilling continues at La Virginia using a single diamond drill supplied by Hermosillo-based drill contractor, Globexplore Drilling Corp.  Drilling by the Company to date builds upon a sizeable database of recent historical work including 52,635 metres of drill core from 188 diamond drill holes, generated by the efforts of previous operators between 2010 and 2013. Silver Viper is expanding upon this work by continuing exploration north and south into prospective untested ground.

QA/QC

Analytical results of drilling intercepts reported by Silver Viper represent samples of halved HQ or NQ2 diameter diamond drill core submitted directly to Bureau Veritas, Hermosillo, Sonora, Mexico.  Samples were crushed, split and pulverized as per Bureau Veritas method PRP70-250, then analyzed for gold by lead collection fire assay fusion on a 30 gram split with AAS finish, and for a multi-element suite including silver by multi-acid digestion with ICP-ES/MS finish. Samples triggering precious metal over-limit thresholds of 10g/t Au or 200g/t Ag were re-tested by lead collection fire assay fusion with gravimetric finish (method code FA530.  Silver Viper monitors QA/QC using commercially sourced standards and locally sourced blank materials inserted within the sample sequence at regular intervals.

Silver Viper has possession of all current and historical diamond drill core and sample pulps as generated on the property since 2010.  The Company has conducted a review of the historical drilling data by physical checks of existing drill pads and drill core and verified the tenor of mineralized intervals by portable XRF on core and sample pulps. Silver Viper has further confirmed the veracity of historical data by diamond drilling of ten core holes at Las Huatas, Con Virginia, and the northern extension of El Oriental target areas. This work confirms the accuracy of location and ranges of mineralization as indicated by the 2010-2013 database.
