Tungsten Mining NL has seen strong investor interest as its Mt Mulgine project in Western Australia remains the core asset, supporting a market cap around AUD 300 million and a near-195 percent share price rise over the past year as the company progresses engineering studies and development pathways for staged commercial milestones. In Western Australia and beyond, Catalina Resources Limited has identified a broad, previously underappreciated tungsten-bearing system at the Santy Well Prospect within its Tallering Project, signaling a meaningful expansion of mineral potential. Highlights from Catalina’s review include tungsten rock-chip values up to 60.1% W (75.8% WO3) and multiple high-grade RC drill intersections such as 17 meters at 0.178% WO3 from 79 meters, with a notable 4 meters at 0.367% WO3 that includes higher-grade sub-intervals. The company is integrating historical data with recent field reconnaissance and 24 rock-chip samples to validate results and refine geological interpretation, aiming to quantify the scale and significance of the tungsten system. Catalina’s updates have coincided with positive market activity, with CTN shares trading higher on July 21, 2026, reflecting investor enthusiasm for the project potential. The overall narrative emphasizes tungsten’s growing importance as a critical mineral and the accelerating exploration strategies around Tallering and Santy Well as part of Catalina’s polymetallic opportunity.
