Homerun Resources Inc. has delivered the first order under the previously announced sales distribution agreement with Cristal Sand Group Ltda. for the sale of high-purity industrial silica sand extracted from the Santa Maria Eterna silica sand district in Belmonte, Bahia, Brazil.

Further to the press release dated March 24, 2026, the company is delivering an initial order to Cristal Sand for customers in the Brazilian market and a sample order for testing by customers in the United States.

Brian Leeners, chief executive officer of Homerun, commented: "Today, we take the first step in the path to scaling our unique silica sand asset into a revenue-generating business. I want to thank everyone on the team at Homerun that has worked diligently for the last three years to get to this starting point, and we look forward to making this same announcement for our 3N, 4N and 5N solutions as they roll out over the coming months."
