Second Quarter Operational Review

Overall production was in line with Company budget for the second quarter despite extreme weather conditions resulting in less than expected processed tonnes. The decrease in copper production is mainly explained by the decrease in processed ore along with a slight decrease in head grade over the same period last year. The gold output slightly improved due to an improvement in gold recovery relative to Q2-2020. The operation remains on track to deliver on set guidance throughout the remainder of the year.

The Company continues to closely monitor developments around the COVID-19 pandemic and continues to maintain strict preventative measures at the El Roble mine site, La Plata project, as well as our corporate offices to safeguard the health of its employees, while continuing to operate effectively and responsibly in its communities.

Note: Metal production figures are subject to adjustments based on final settlement. The reported results are preliminary in nature and are awaiting independent lab verification.

Concentrate Inventory

The number of shipments the Company can export in any given quarter depends on several variables some of which the Company does not control, hence there may be an inherent variability in tonnes shipped quarter to quarter.

Corporate Update

The Company is currently in the process of renewing the title on its claims hosting the El Roble property which under the current agreement are set to expire in January 2022. The renewal process was started two years prior to expiry in January 2020 with a submission to the Colombian National Mining Agency in accordance with governing laws and is currently at an advanced stage. The Company believes it has followed and fulfilled all of the renewal requirements at this stage.

In a separate process, the Company continues to receive claims from the Colombian National Mining Agency related to payment of copper royalties, despite the fact that the matter is before the tribunal. For more details please refer to Company’s previous news release announced on April 26, 2018. The Company, based on the advice of its Colombian legal counsel, continues to maintain its position that these claims lack merit and are in violation of Colombian law.

The Company will continue to advance these two separate processes and will be providing updates on their progress in due course.

El Roble Mine

The El Roble mine is a high grade, underground copper and gold mine with nominal processing plant capacity of 1,000 tonnes per day, located in the Department of Choco in Colombia. Its commercial product is a copper-gold concentrate.

Since obtaining control of the mine on November 22, 2013, Atico has upgraded the operation from a historical nominal capacity of 400 tonnes per day.

El Roble has Proven and Probable reserves of 1.00 million tonnes grading 3.02% copper and 1.76 g/t gold, at a cut-off grade of 1.3% copper equivalent as of September 30^th, 2020. Mineralization is open at depth and along strike and the Company plans to further test the limits of the deposit.

On the larger land package, the Company has identified a prospective stratigraphic contact between volcanic rocks and black and grey pelagic sediments and cherts that has been traced by Atico geologists for ten kilometers. This contact has been determined to be an important control on VMS mineralization on which Atico has identified numerous target areas prospective for VMS type mineralization occurrence, which is the focus of the current surface drill program at El Roble.
