SME SoCal Dinner Meeting: Breathing New Life Into The DeLamar Mine

4821 Mills Circle,Ontario CA 91764

10 November, 2022

Description

Abstract: Mining at DeLamar dates back to the late 1800's and more recently from the 1970's through the 1990's. The DeLamar project is located in southwestern Idaho approximately 100 miles (160 km) from Boise. The project includes the historic Kinross’ DeLamar Mine that closed in 1998 due to low precious metal prices. The historic DeLamar Mine produced 1.6 million ounces of gold and 100 million ounces of silver. This presentation will briefly examine past mining and history in the area. The main focus of the presentation will be an explanation of Integra Resources work towards re-opening the DeLamar mine. Since acquiring the DeLamar Project in late 2017, the Company has demonstrated significant resource growth and conversion while providing a robust economic study in its Pre-feasibility Study (PFS). Some highlights from the PFS and subsequent studies include: • Heap leach stage pre-production Capex of US$273 million • LOM site level AISC of US$813/oz on an AuEq co-product basis • Average annual production of 136,000 AuEq from years 1 to 7 • Heap Leach only scenario significantly reduces surface area disturbance and lowers water and power usage, among other benefits The Company continues to be focused on resource growth through brownfield and greenfield exploration and further de-risking of the Project. DeLamar will rise again. Speaker: Tim Arnold is the Chief Operating Officer of Integra Resources Corp.
