Vancouver, June 29th, 2017 - Montan Mining Corp.. (TSXv: MNY | FSE: S5GM | SSE: MNYC) ("Montan" or the "Company") is pleased to announce that the Company has arranged an extension of its Term Sheet with Pacific Alliance Capital Group Ltd. ("Pacific Alliance") for the purchase, by Montan, of the Peruvian companies Kairos Capital Peru S.A.C ("Kairos") and M&S Transportes y Servicios Generales S.R.L ("Mirador") from Pacific Alliance (please refer to the News Release of February 16th, 2017). The extension is granted until August 30th, 2017 to facilitate completion of the transaction closing requirements. The key assets ("Pacific Alliance Assets") held by the companies under acquisition include the 100% owned 125 tonnes per day ("TPD") Mirador Processing Plant located in Chimbote, Peru and six (6) 100% owned mineral concessions.

The Company would like to confirm that the Kairos transaction, which will provide the Company with existing (and growing) cash flow from the Mirador base and precious metals mill, is proceeding on a revised schedule, timed to permit full compliance with TSX requirements and Personal Information ("PIF") filings.

Operational Update: The Mirador plant is fully operational at 125 TPD through its copper processing line and presently has a two-month waiting list queued for processing through its flotation circuit.

Forward planning for the operational start-up of the Company's 100% owned Cerro Dorado plant has also been ongoing. Detailed evaluation of the volume and quality of gold bearing mineral bound for Chala and Nazca out of the Atico Valley where the Cerro Dorado plant is located has shown that more than 6,000 tons of quality feed passes by the plant location monthly. Negotiations with potential suppliers confirm a strong business case for near-term start-up at Cerro Dorado.

Kairos SAC acquisition financing: The Company and Cartesian Royalty Holdings Pte. Ltd. ("CRH") have terminated the Binding Term Sheet for debt financing of the cash component of the Kairos/Mirador acquisition (please refer to the News Release of April 25th, 2017). Management acknowledges the professional work undertaken by CRH towards closing a definitive agreement with the Company. The Company is rapidly advancing alternative financing options that are attractive to both Montan and Pacific Alliance.

On behalf of the Board of Montan.
