Cornerstone Capital Resources Inc.: Cascabel Pre-Feasibility Study Update

Cornerstone has been informed by joint venture partner and project operator SolGold Plc that with the recent appointment of new SolGold CEO and Managing Director Darryl Cuzzubbo effective December 1, 2021, SolGold has determined to delay the release of the PFS. This will enable confirmation of various assumptions impacting the PFS, including whether what are currently considered as upside options should in fact be further evaluated and incorporated as part of the PFS base case so as to provide a more indicative and robust value of the Cascabel project. Upside options under review include earlier underground access, mine and mill optimizations, extending Cascabel Resources, hydroelectric power, among others, offering further optionality and potential for improved economics.

Subject to the determination on the above assumptions, the PFS is well progressed and SolGold anticipates that it will support its management's expectations of a robust and prospective project.

An update on when the PFS is expected to be completed will be provided at the upcoming SolGold AGM on December 15^th 2021.
