The December Quarter was a prime example of what Altitude Minerals is all about. Not only did we get out on the ground and drill-test several potentially large-scale, high-value targets in the Macquarie Arc, but we also worked hard to keep our target pipeline replenished and set ourselves up for the year ahead. I’m personally very excited by new copper-gold targets emerging at the Theseus Project in the Macquarie Arc, as well as the potential for discovering silver and gold on our ground in Nevada.
Over the coming quarter, we aim to maintain this momentum. I look forward to receiving results from our recent drilling and testing new prospects, and, of course, sharing this news flow with you - our investors.
