VANCOUVER, BC and TORONTO, ON (July 8, 2019) – Atico Mining Corporation (“Atico”) (TSX-V:ATY; OTC:ATCMF) and Toachi Mining Inc. (“Toachi”) (TSX-V:TIM; OTC:TIMGF) are pleased to announce that they have entered into a definitive agreement (the “Agreement”) today, whereby Atico will acquire all of the issued and outstanding shares of Toachi pursuant to a plan of arrangement (the “Transaction”) to create a new Latin American focused copper-gold Company.

Under the terms of the Agreement, all of the Toachi issued and outstanding common shares will be exchanged on the basis of 0.24897 Atico common shares for each Toachi common share (the “Exchange Ratio”). The Exchange Ratio implies consideration of approximately C$0.073 per Toachi common share, based on the closing price of Atico common shares on the TSX Venture Exchange (“TSX-V”) on July 5, 2019. This represents a 47% premium to Toachi’s closing price and a 49% premium to the 20-day volume-weighted average price (“VWAP”) as at July 5, 2019 on the TSX-V.

Upon completion of the Transaction, existing Atico and Toachi shareholders will own approximately 83% and 17% of the pro forma Company, respectively.

Highlights of the Transaction

Key investment highlights of the combined Company include:

Creation of a leading Latin American copper-gold Company anchored by the producing El Roble mine in Colombia and the high grade La Plata project in Ecuador1
Expanded capital markets presence, increased trading liquidity and an enhanced value proposition
Highly credible leadership team with a wealth of experience in financing, operating and mine development in Latin America
Combined Company provides significant revaluation potential as a producer with growth potential
Opportunity for input cost, development and operations synergies given close proximity and geological similarities
Platform for further consolidation

Fernando Ganoza, CEO and Director of Atico, stated: "We are very pleased to bring this transaction forward for our shareholders that aligns us with our vision of growing the Company into a leading mid-tier producer. Atico has been successful in transforming the El Roble project into an important cash generating asset with high safety, environmental and operating standards. The results of this success have significantly strengthened our balance sheet and positioned the Company for additional value-creating opportunities that can complement the El Roble mine." Mr. Ganoza continued, "We believe the high-grade gold and copper La Plata project provides such an opportunity as the combination of El Roble and La Plata creates a robust platform for accretive growth for both Atico and Toachi shareholders."

Alain Bureau, President and CEO of Toachi, stated: “The robust synergies between both Companies makes this business combination a logical step towards building a peer leading and profitable copper-gold producer in Latin America. The Board, Management and certain major shareholders of Toachi fully support the planned combination between our two Companies. Additionally, the Transaction offers an optimized combination of experienced mining professionals who share common values of protecting the environment and responsibly supporting the development of communities we operate in”.

Opportunity for input cost, development and operations synergies given close proximity and geological similarities
Regional diversification by entering Ecuador, a booming, underexplored jurisdiction that has been recently endorsed by several major international mining Companies

Partnership with experienced mine operators of underground VMS deposits2 in Latin America
Eliminates the single asset risk factor
