Geophysical work by Titan Minerals (ASX:TTM) has delineated a highly prospective corridor of copper-gold porphyry targets at the Copper Duke project.

This follows the completion of a high resolution airborne geophysical survey that further enhanced targeting at the El Huato prospect and identified additional clusters of intrusion centres at the El Huato and Catamayo prospects.

Importantly, the scale, geometry and extent of geophysical anomalism identified at Copper Duke is similar to many major tier 1 porphyry districts in the world including Cerro Casale and Reko Diq.

“We are cautious not to overstate the potential of Copper Duke. It is an exceptional copper gold porphyry exploration project, one that would be attractive to any major mining company and we think results to date support our view,” managing director Laurie Marsland said.

“Our work has identified clusters of intrusion-related anomalism over an area of greater than 12 sqkm, on par with many tier one deposits around the world. And when considering scale, geometry, and geophysical anomalism, in our opinion, Copper Duke is similar to many major porphyry districts in the world.

“We are very excited to own the Copper Duke Project and about its potential to create value for our shareholders as our understanding of the asset unfolds.”

Copper Duke porphyry potential

Copper Duke is an early stage porphyry copper-gold/epithermal gold project just 18km east of Titan’s flagship Dynasty gold project.

It hosts several mineralised porphyry style systems confirmed in surface geochemistry and mapping work to date.

The company noted that significant gold and copper values at surface such as 28.3m at 1.1 per cent copper within the Lumapamba prospect and 12.4m at 3.04 grams per tonne gold and 1.8 per cent copper at the Catamayo prospect are associated with both disseminated style mineralisation and quartz hosted veining.

To the north of the contiguous trend of prospects, the underexplored Ningomine prospect has the largest footprint of geophysical anomalism featuring vein hosted gold and copper mineralisation across several scattered outcrop areas.

Geophysical survey results have defined an extensive corridor hosting porphyry-related features.

Multiple clusters of intrusive centres in a 9km long by up to 2km wide trend are coincident with outcropping porphyry style mineralisation confirmed at surface.

Existing high tenor gold and copper surface mineralisation from trench and channel sample activity is associated with several of the geophysical anomalies reported, and several additional magnetic anomalies in the extended corridor require follow-up field work in this underexplored porphyry field.

The company is currently advancing a surface sampling and mapping campaign to follow up on the geophysical results, which is expected to lead to the ranking of multiple drill targets for maiden drill testing later this year.
