Brokopondo

Opportunity: Big Cobalt Target – Inexpensive to test and advance

Stage: Drill target identification in preparation for 2018 drill program

Overview

  • The Brokopondo Cobalt Project is an ~8,900 hectare laterite hosted cobalt-manganese project with historic grades of 0.5-1.5% Co sampled by the USGS in 1993. The Company views the Brokopondo Project as well positioned for fast and inexpensive exploration to define a meaningful resource that has the potential to address global cobalt demand.
  • The Brokopondo Project is a laterite-hosted cobalt-manganese showing in an area with paved road access, high-tension power lines crossing the project and gentle terrain. 
  • Laterite hosted cobalt deposits tend to be free digging, low arsenic sources of cobalt. The Company believes these types of deposits are amenable to a simple crush and leach process, which can be designed and built on a timeline that could address the market demand for additional cobalt supply.

Location

The property is located in Suriname and lies 85 kilometres south of the port capital of Paramaribo. The Brokopondo property is accessible by a paved highway and has high-tension power lines traversing it. Historic exploration for bauxite and placer gold mining has left the project area crisscrossed by tracks and trails and well suited for rapid exploration and development.

The Brokopondo Cobalt Property

ePower Metals has acquired an ~8,900 ha prospecting permit in Suriname based on historic USGS reports of laterite hosted Cobalt-Manganese with grades of 0.5-1.5% Co, (USGS MRDS 1993 - The grades stated in the USGS reports have not been verified by the Company, and readers are cautioned not to place undue weight on such results. The historical grades are considered relevant; however the reliability, assumptions, parameters and methods used in preparing the reports are unknown.).

  • Internally generated
    • Low acquisition cost < $50,000 
  • Big Target - large land package
    • 8900 hectares
  • Historic grades of 0.5-1.5% Co sampled by the USGS in 1993*
  • Excellent infrastructure
    • Paved road access
    • Power lines cross property
    • 85 km from tide water

Targeting laterite hosted cobalt-manganese deposits

ePower Metals target model is similar to cobalt/manganese deposits delineated in Cameroon. For an example, Geovic Mining Corp. has identified cobalt-manganese hosted in asbolane and/or lithiophorite minerals with a estimated Measured Mineral Resource of 59.8MT grading 0.24% Co, 1.37% Mn and 0.68% Ni, (NI43-101 report; Geovic Mining Corp. Nkamouna and Mada Deposits, June 2, 2011. These resources are historic in nature and while we believe the resources have been completed to the standards of the day, they should not be relied upon by the reader). These laterite deposits are formed over tropically weathered ultramafic bodies, which results in the enrichment and concentration of elements such as cobalt, nickel and manganese in the oxide facies. Cobalt mineralization is found in concretions with manganese and nickel. These concretions are amenable to physical upgrading through screening and washing which results in a concentrate, which can be 2 to 4 times higher than run of mine ore. These coarse-grained concentrates can be processed through a conventional crush and vat leach process that typically is simpler and cheaper than pure clay or silicate type nickel-cobalt laterite deposits which require high pressure acid leach processing with associated complex and capital intensive technologies.

Laterite hosted cobalt-manganese deposits tend to be free digging, low arsenic sources of cobalt. The Company believes these types of deposits are amenable to a simple crush and leach process, which can be designed and built on a timeline that could address the market demand for additional cobalt supply.

2018 Objectives

Target simple and inexpensive to test

  • Summer Plans
    • Property wide soil sample - 200m x 200m grid
    • Zero in on anomalous regions – 50m x 50m grid
    • Definition drilling to begin
  • Potential to rapidly advance
    • Trado drill/auger – 3 holes/day on discovery
    • Objective to define resource

Budget = US$350,000 for initial program
