DEVELOPMENT AND EXPLORATION IN ECUADOR

Loma Larga

Location: Southern Ecuador
Ownership: 100%
Target: Gold
Status: Feasibility Study

INV Metals announced the positive results of the Feasibility Study (“FS”) on the Loma Larga gold property in November 2018. The FS contemplates an underground mine with a daily production rate of approximately 3,000 tonnes per day (“tpd”)in the early years and reaching 3,400 tpd in year 5, resulting in a higher average annual gold recovered production of 206,000 ounces over an initial projected life of mine of approximately 12 years. The FS includes new capital cost estimates, detailed engineering and mine plans, and environmental studies.

Adjusted Operating Costs and All-in Sustaining Costs are calculated in accordance with the World Gold Council’s Guidance on Non-GAAP Metrics – All-In Sustaining Costs.

CIM 2014 Definition Standards were followed for Mineral Resources.
Mineral Resources are reported at an NSR cut-off value of US$60/t.
Mineral Resources are estimated using a long-term gold price of US$1,450 per ounce, silver price of US$22.00 per ounce, and copper price of US$3.50 per pound.
The formula used to calculate gold equivalence (AuEq) is: (Au g/t x 31.31 + Ag g/t x 0.44 + Cu% x 46.19) ÷ 31.31. The formula used to calculate AuEq ounces is: AuEq Oz = (Tonnage x AuEq g/t) ÷ 31.31.
Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
Mineral Resources are inclusive of Mineral Reserves.
Average bulk density is 2.7 t/m3.
Numbers may not add due to rounding.

CIM 2014 Definition Standards were followed for Mineral Reserves.
Mineral Reserves include long hole and drift-and-fill stopes as well as development in ore.
Mineral Reserves are reported at an NSR cut-off value of US$60/t.
Mineral Reserves are estimated using a long-term gold price of US$1,250 per ounce, silver price of U$18.00 per ounce, and copper price of US$3.00 per pound.
Average bulk density is 2.7 t/m3.
Numbers may not add due to rounding.

The Mineral and Resource estimates were prepared in accordance with the 2010 CIM Definition Standards for Mineral Resources and Reserves as incorporated by references in National Instrument 43-101. Further information about the Project will be contained in the Technical Report when filed.
