About Tamar Minerals Plc

Who We Are

Our Expertise

Our Expertise

At Tamar Minerals Plc, we are an experienced metals exploration and technology team. We have worked around the world  reinterpreting historic exploration and mining data to find ore zones previous explorers did not have the technology or understanding to uncover.  

Our Expertise

Our Expertise

Our Expertise

Over decades we have captured and digitised hundreds of years of data from the mines of Devon and Cornwall. From this we have built detailed models to identify where historic miners recovered high grade mineral ores and where the extension of those mineral systems remain untouched.

Our Mission

Our Expertise

Our Mission

Our mission is to unlock the UK's critical mineral assets, delineating and recovering copper and tin assets that were left behind in the great mines that once fed the industrial age. Today these same critical minerals are in demand to transition our economies to a low carbon greener future.

Our Projects

Devon Great Consols

Devon Great Consols (DGC) was the largest copper sulphide vein system in Southwest England, with initial exceptionally high copper grades. Tin mineralization was identified deeper in Wheal Emma, indicating polymetallic potential. The deposit has not been subjected to modern drilling techniques since its closure in 1903, leaving much of the DGC Main Lode unexplored. Tamar has a drilling program planned to test the unmined down-plunge and along-strike potential.

Wheal Vor

Great Wheal Vor was the second-richest tin mine in Cornwall during the 19th century. Importantly, operations there ceased in the early 20th century not due to ore exhaustion, but because of mineral rights boundaries. Tamar has secured the mineral rights over the downward and northward continuation of the Main Lode, suggesting unmined potential below and adjacent to the historical workings. Tamar plans a drilling program to investigate this depth continuation

Australian Gold Assets

Tamar also holds a minority interest (49%) in the Specimen Hill copper-gold project through its 100% owned Australian subsidiary, Signature Gold Pty Ltd. This discovery was made by previous management at Tectonic Gold and is now being farmed out to ASX listed White Energy Group (ASX: WEC) who are advancing the project. Tamar retains a 3% royalty in perpetuity over the project and is due an A$2 million cash payment on completion of the farm out.
