Greatland Gold PLC’s Havieron gold-copper discovery in the Paterson Range

Coffee with Samso Episode 147 with Calum Baxter, former Chief Technical Officer of Greatland Gold PLC (AIM:GGP, OTC:GRLGF) is the second episode of the Exploration Discovery Series, which is all about mineral exploration discoveries.

It’s a cold and wet morning, but that doesn’t detract from what we’re going to tell you about Greatland Gold PLC’s discovery of Havieron (AIM:GGP, OTC:GRLGF) . in 2018. It was a huge success and it is now a gold and copper mine nearing the production stage.

The company’s website states that the project is currently being developed in a joint venture with Newcrest Mining, Australia’s largest gold producer. Havieron is just 45km from Newcrest’s Telfer mine. This allows the project to leverage Telfer’s existing infrastructure and processing plant to significantly reduce the project’s capital costs and carbon footprint for a low-cost development path under the ore payment agreement.

As per the company’s latest presentation, the updated Ore and Mineral Reserve data is shown in Figure 2.

The significance of these numbers is that the mine has been discovered. In most cases, investors only look at the results of a long mineral exploration journey.

The journey of discovery is never an overnight process. In reality, the discovery of any mineral deposit has a minimum lead time of years, and development usually takes decades (including exploration and resource development).

The Coffee with Samso – Exploration Discovery Series aims to showcase discovery as well as the most exciting parts of exploration journeys. The inside scoop on what happened, did and didn’t work out leading up to the reveal is the fun part of the conversation for me.

The Havieron discovery is one of the latest successes achieved as management has kept faith and applied the principles of mineral exploration. As an exploration geologist, the Havieron discovery excites me. The pursuit of discovery is one of the most fulfilling feelings one can experience. The idea of ​​starting a company to get funding to chase elephant deposits is high on my list.

That’s why I want to bring these stories to the Samso platform so that the average investor out there can get an insight into these journeys.

I hope you enjoy the video and feel the “excitement” that was in the room when Calum and his associates received the results of the drill.
