Highlights The positive results of the 59-day Phase 2 field test (September to November 2020) described herein expand upon the 24-day Phase 1 results (August 2020) described in the Company's February 16, 2021 news release Significant rates of carbon sequestration were noted on a continuous basis throughout Phases 1 and 2 under all test conditions, with the highest rates of sequestration occurring in tailings subjected to churning at regular intervals to encourage greater exposure of the crushed material to air Measurements during the combined 83-day Phase 1 and 2 field programs indicate capture of a total of 5.8 grams of CO 2 for each kilogram of crushed Baptiste tailings exposed to air by churning on a regular basis to a depth of 12 cm
