About Castillo Copper 

Castillo Copper Limited is an Australian-based explorer primarily focused on copper across Australia and Zambia. The group is embarking on a strategic transformation to morph into a mid-tier copper group underpinned by its core projects: 

· A large footprint in the Mt Isa copper-belt district, north-west Queensland, which delivers significant exploration upside through having several high-grade targets and a sizeable untested anomaly within its boundaries in a copper-rich region. 

· Four high-quality prospective assets across Zambia's copper-belt which is the second largest copper producer in Africa. 

· A large tenure footprint proximal to Broken Hill's world-class deposit that is prospective for zinc-silver-lead-copper-gold. 

· Cangai Copper Mine in northern New South Wales, which is one of Australia's highest grading historic copper mines. 

The group is listed on the LSE and ASX under the ticker "CCZ."
