Empresa Mixta Eco-Socialista “Siembra Minera”, S.A. Business Plan Utilize Original GR’s Brisas Mine, Process Plant & Infrastructure Design Double Size of Process Plant with Mirror Image Design Optimize facilities layout Solid Basis for Final Design to Update Capital & Production Costs (Detailed Engineering & Design 85% Complete – Procurement 68% Complete) 6
Brisas-Cristinas Project Rationale • Brisas– Cristinas is one continuous orebody • Development reduces environmental impact • Most rational way to exploit the deposit (art. 5 Mining Law) • Produces the highest rate of return • Excellent Potential to increase reserves • Allows reclamation of entire mining district devastated by years of illegal mining 7
Proj ect Area S atellite Photo Early 2017 8
Brisas-Cristinas Project Recent Addition to Plan • Add separate Oxide Saprolite Process Plant • Considering Gravity Gold only vs. Cyanidation Plant • Provides Au production in 18 to 24 months vs. 4 years for large scale plant • Provides Earlier Revenue Stream 9
Siembra Minera GR Engineering (Barbados) Inc. Current Activity Working on design & cost on two separate and concurrent processing plant scenarios. 1. An oxide saprolite ore processing plant that would provide an early phase production and cash flow. A smaller plant that could be constructed in a two year time frame. 2. The large scale processing plant for the sulfide saprolite and hard rock ores which would take approximately four years to put into production.

Siembra Minera GR Engineering (Barbados) Inc. Consultants & Their Current Activities RPA started on a NI 43-101 report and (PEA) Preliminary Economic Assessment Includes updated resource estimates and cost estimates Samuel Engineering providing support to RPA on large scale process plant Includes design and capital cost estimates Samuel Engineering also providing preliminary design and cost estimates on an oxide saprolite processing plant Tierra Group International, LTD providing support to RPA on large scale process plant tailings dam Includes design and capital cost estimates Tierra Group International, LTD also providing preliminary design and cost estimates on an early stage oxide saprolite processing plant tailings dam facility
Siembra Minera GR Engineering (Barbados) Inc. Consultants & Their Current Activities Ingenieria Caura, S.A. working on Early Works (earthwork, timber clearing and road building) permitting Also preparing Venezuela Environmental Impact Statement (VEIS) and permitting of both large and small process plants AATA International Inc. working on an International Environmental and Social Impact Assessment (IESIA) A document required for Financing from International Bank and other financial Institutions Prizma LLC providing input and assistance to Ingenieria Caura and AATA International for the social aspects of the VEIS and IESIA Global Resource Engineering providing input and assistance to Ingenieria Caura and AATA International for the geo chemistry and water quality aspects of the VEIS and IESIA
Siembra Minera GR Engineering (Barbados) Inc. Consultants & Their Current Activities Inespro, C.A. (Ingeniero Rafael Borges y Asociados) prepared the Quarry Concession Application. Also will be working to update the Feasibility Study for the quarry concession to obtain the Exploitation Certificates CVG-TECMIN, C.A. prepared application for Permit to Occupy the Land (AOT). Also prepared a preliminary report on current Social & Environmental situation at the project site area It will also be working on an Environmental & Social Audit before breaking ground. An engineering & environmental state owned company located in Bolivar State that will provide support along the early phases of project development.
16 Design Updates
Alternatives for Improvement/Cost Savings 1. More efficient site layout • Reduce deforestation and earthwork requirements • Improve operability • Makes room available for Oxide Saprolite plant 2. Location of the Oxide Saprolite processing plant next to Main Project Plant will benefit from: — Sharing certain processing facilities (Gold Elution & Refining) — Avoids having to build a second tailings dam facility — Reducing size of powerline corridors — A single production center: more efficient and secure operation — Eliminating duplicate infrastructure — Topo survey and geotech work already complete
Alternatives for Improvement/Cost Savings 3. Larger equipment sizes based on availability of recently developed equipment • One larger crusher (current 2 crushers – 1.524 m x 2.261 m) Current – 4 SAG mills (11.58 x 6.7 m, 20 MW), 8 ball mills (6.7 • m x 11.125 m, 9,325 kW) Potential – 2 SAG mills (12.2 x 8.8 m, 28 MW), 4 ball mills (7.9 • m x 10.1 m, 10,500 kW) Larger leach tanks to reduce the overall footprint • Larger flotation cells (current rougher flotation 8 banks of 6 • each for 48 - 160 m 3 cells; > 630 m 3 cells now available and would only need 2 banks of 6) Optimize carbon handling and refinery •
