Underneath the Camino Rojo oxide reserve, there is a substantial sulphide resource containing approximately 7.3 million ounces of gold in the measured and indicated (M&I) category. Various development scenarios are currently under consideration, and directional drilling is ongoing to assess the feasibility of underground mining and the establishment of an independent processing facility. The preliminary results from the underground drilling programs indicate the presence of higher-grade zones that are economically viable over significant mining widths.

Additionally, the Company is conducting metallurgical testwork to determine the most suitable processing approach. Apart from the option of underground mining, the base case scenario involves open pit mining. Orla Resources also retains the right to process the extracted minerals at Newmont's Penasquito facility, located 50 kilometers away from the Camino Rojo site.

In 2023, the Company plans to undertake another phase of closely-spaced oriented drilling. The primary objectives of this drilling program are to enhance confidence in the underground development approach, assess the potential size of the underground resource, and gather essential data for the Preliminary Economic Assessment (PEA).
