Aharon Zaetz quoted “ We are delighted with the level of interest in RML and with the high quality of investors who believe in our vision, potential and upside of Resolution’s Horse Heaven Project. We eagerly look forward to progressing work on both the Golden Gate and Antimony Ridge targets at Horse Heaven. The recent rock chip results are extremely encouraging, and we are hoping that the current drilling program, which is well underway, will demonstrate to the market the significant potential of our highly prospective antimony, gold and tungsten project. With the proposed listing of RML on the NASDAQ, we are aiming to be trading shoulder to shoulder with the likes of our next door neighbour, Perpetua Resources, and other U.S. critical metals giants such as MP Materials Inc. ”

The Company intends to use the funds raised from the Placement to:

• explore downstream critical mineral processing initiatives;

• continue its drilling campaign at the Horse Heaven Project;

• future drilling and surface sampling programs;

• identification and acquisition of additional strategic assets;

• progress its other exploration projects; and

• working capital.

About Horse Heaven

With a rich history of past antimony, tungsten and gold mining, the Horse Heaven project area has supplied the U.S. Government with significant quantities of antimony and tungsten in World War I, World War II and the Korean War. Horse Heaven is located directly adjacent to Perpetua Resources’ Stibnite Antimony & Gold Mine (PPTA.NAS, A$3 billion market cap) in Idaho, USA. Horse Heaven’s geological model is a direct analogue to Stibnite, bearing a strong resemblance to its A$3 billion neighbour. The Resolution team is fully committed to restarting mining operations at Horse Heaven to restore the critical metals supply chain in the United States.
