IFC, a member of the World Bank Group, has entered into a subscription agreement with Tinka Resources Limited to acquire, subject to customary conditions, 3,950,000 units issued by Tinka at a price of C$0.48 per unit pursuant to the second tranche of a non-brokered private placement for an aggregate consideration of C$1,896,000. Each Unit is comprised of one (1) common share and one-half (0.5) of one common share purchase warrant. Each Warrant entitles the holder to purchase one Common Share of Tinka at an exercise price of $0.75 per Common Share for a period of one year following the closing of the Private Placement.

The 3,950,000 Common Shares to be acquired by IFC represent approximately 1.6% of the total issued and outstanding Common Shares prior to the closing of the Private Placement, and assuming the exercise of the 1,975,000 Warrants also to be acquired, represent in the aggregate approximately 2.3% of the total issued and outstanding Common Shares prior to the closing of the Private Placement.

Prior to the closing of the Private Placement, IFC held 25,945,754 Common Shares representing approximately 10.2% of the total issued and outstanding Common Shares or 12.9%, assuming the exercise of its privately held 7,848,837 common share purchase warrants.

Following the closing of the Private Placement, IFC will hold 29,895,754 Common Shares representing approximately 11.5% of the total issued and outstanding Common Shares or 14.8%, assuming the exercise of its privately held 9,823,837 common share purchase warrants.

IFC executed the Agreement as part of its regular portfolio management. It will maintain its holdings in Tinka for investment purposes and may, in the future, take such actions in respect of its holdings as it deems appropriate in light of the circumstances then existing.

The Private Placement is expected to close on or about April 27, 2018 assuming the conditions precedent to closing are satisfied.

Tinka's head office is located at 1305 – 1090 West Georgia Street, Vancouver, B.C. V6E 3V7. Its shares trade on the TSX Venture Exchange.
