Tarrant Elkington, Snowden Optiro's Executive General Manager

In May, a significant number of our geologists attended the AusIMM Resource Estimation conference held in Perth. Apart from being an excellent technical conference, it provided a wonderful opportunity for our global team to connect and build relationships. We had the privilege of having several international consultants fly in to be a part of this event, further strengthening our collaborative network.

Welcome to Snowden Optiro’s newsletter! We are thrilled to share our knowledge and passion for solving technical challenges in the field of Mineral Resources and Ore/Mineral Reserves with all of you. Our team takes immense pleasure in providing valuable content to support the industry’s professional development.

As I write this, I find myself amidst a tour across four continents, which truly emphasizes the global nature of our industry and our business. In the spirit of expansion, we have recently launched our Advisory presence in Peru and Chile, complementing our existing offices in Australia (Perth and Brisbane), South Africa, United Kingdom, Brazil, and Canada. This allows us to provide our clients with support in various languages, no matter where they are located.

At Snowden Optiro, we take immense pride in what we are building. We hope that this pride is evident in the content of this newsletter. We are always open to suggestions and feedback, so please don’t hesitate to reach out with any ideas for our future editions.

Thank you for being a part of our journey.
