Nevada Rose Project

The Nevada Rose Project is situated about 145 kilometres (km) SSE of Carlin, NV and roughly 370 km NNE of Las Vegas, NV, towards the southerly intersection of the Battle Mountain-Eureka and Independence-Eureka Trends, approximately 12 km SW of the Ruby Hill mining district near Eureka City.  The Company has the option to acquire a 100% interest in the Nevada Rose Project, which is a group of 22 unpatented lode claims located in NE Nevada (see Minfocus new release dated March 5,2020). 

The Nevada Rose project targets a precious-metals system striking over a one-kilometre length on the edge of the pediment, which comprises previously identified silver-rich zones within a larger zoned precious metal system.  The host rock is a sequence of Silurian dolostone overlain by Devonian limestones that dips gently east toward pediment cover.

Regional mapping by Homestake Mining in the 1990s identified aerially extensive bedded and high-angled (structurally emplaced) jasperoid.  These 79 samples averaged 180 grams per tonne (g/t) silver (5.2 ounces per tonne (oz/t) Ag) with no appreciable gold and with individual assays of up to 2,050 g/t silver (60 oz/t Ag).  Zones of zebra-textured dolomite associated with dissolution collapse breccia carry more than 30 g/t (over one oz/t) Ag suggesting targets that should yield thicker zones containing multiple ounces of silver when the core jasperoid is added.

Anomalous gold mineralization has, in addition, been identified in two locations on the Nevada Rose property.   Multiple samples from a bleached zone 200 m wide dipping under the pediment, returned over 100 parts per billion (ppb) gold.  More recent work showed a strong gold zonation toward the pediment coincident with high zinc values.  A shear zone on the edge of the pediment assayed at 0.58 g/t Au (0.02 oz/t Au) and 380 g/t Ag (11 oz/t Ag).  In 2007, a reverse circulation (RC) drill program in the zone by Piedmont Mining intercepted six metres (20 feet) of 0.91 g/t Au and 3.4 g/t Ag.  Another RC drill hole in the same zone intercepted 44 metres (144 feet) of 0.26 g/t Au and 3.1 g/t Ag.  Mineralization in the latter RC drill hole remains open.  A second zone approximately 850 metres to the north produced a gold assay of 0.4 g/t.  Historic data indicate the presence of a mineralizing system with disseminated gold in addition to the multi-ounce silver showings that dominate the property near surface.

To date, the Nevada Rose has not been the subject of recent systematic exploration and past work had not evaluated the identified targets near to the historic workings or the areas of jasperoid which host bonanza grade silver.  Minfocus plans to undertake a compilation and evaluation of regional and historic data. 

Potential drill targets include the intersection of bedded and steeply emplaced structural jasperoids running multi-ounce silver as well as collapse breccias running multi-ounce silver.  The lower grade anomalous gold zones where multiple samples running hundreds of ppb gold also require further testing.  The shallow dip of surrounding rock units may indicate favourable host rock units at modest depths.
