Valterra is exploring for mineral deposits in British Columbia, Canada, Chihuahua, Mexico and Mato Grosso, Brazil. The company is well-structured with an experienced geologic team, management group, and Board of Directors.
The recent acquisition of the Lima Gold Project in Mato Grosso, Brazil is an exciting acquisition for the company, which management believes is a rare opportunity to acquire a highly-prospective gold property at exceptionally attractive terms which has the potential to be fast-tracked to production at a very low cost. The property adds to a high-quality continental portfolio of properties which now spans North and South America.

Properties in North America include the Swift Katie Au-Cu project in British Columbia, Canada and the Los Reyes Cu-Au project in Chihuahua, Mexico.

The Los Reyes Project in Chihuahua, Mexico adds an exciting early stage, high-grade Cu-Au skarn target within an underexplored area east of the historic mining community of Hidalgo de Parral, with artisanal mining of near-surface oxides reportedly containing grades up to 8% Cu.*
Surface sampling of waste dumps in November 2019 related to the artisanal workings and limited outcrop chip samples returned 22 of 28 samples with Cu values >1% Cu at an average grade of 3.1% Cu and up to 5.9% Cu. The anomalous samples contain elevated precious and base metal values up to 0.57g/t Au, 25.3g/t Ag, 0.47% Mo and 1.7% Zn. Anomalous samples were collected along the full 800m strike-length of the exploration target on the property with most of the samples collected in 5 clusters adjacent to open cuts and pits related to the historically mined portions of the trend.
Valterra is also active in south-eastern BC at Salmo and controls the >8,300 hectare ‘Swift Katie’ Au-Cu-Ag porphyry system which also includes a high-grade gold system at the southern Swift target. The ‘Swift’ target has been a main focus for Valterra in recent years. Highlights from the 1980s and from Valterra’s 2014, 2016 and 2017 diamond drilling includes:
- 11.5 g/t Au & 6.7 g/t Ag over 2.5m in hole SK17-015
- 1.1 g/t Au & 0.5 g/t Ag over 22.6m in hole SK17-015
- 3.1 g/t Au, 2.0 g/t Ag over 8.6m from hole SK17-019
- 0.96 g/t Au over 6.6m in hole SK16-011
- 13.3 g/t Au, 201 g/t Ag & 0.33% Cu over 3.5m from SK14-002
- 1.83 g/t Au over 10m from hole 87-6, including 5.15g/t Au over 2.0m*

In 2017, drilling successfully offset two high-grade gold zones located along a 1,000 metre strike-length of the Swift gold structure.

The ‘Katie’ deposit is an alkaline Cu-Au-Ag porphyry system. The potassic core has elevated Cu and Au values and is surrounded by a broad propylitic zone. Sulphide minerals include pyrite, chalcopyrite with minor sphalerite, tetrahedrite, bornite and molybdenum.
The project has excellent infrastructure with major highways nearby, established forestry routes on-site, proximal high capacity power network nearby and a skilled regional workforce (pop. >25,000 in the district). Moreover, BC/Canada provides many generous investment and tax advantages in a politically stable jurisdiction.
