About Prospectiva Resources Ltd.

Prospectiva Resources is a Brazil-focused copper and gold exploration company advancing a district-scale portfolio of 100-per-cent-owned projects across the highly prospective but underexplored Borborema belt in northeastern Brazil. The company's land package comprises 35 mineral exploration licences covering approximately 335 square kilometres across the states of Pernambuco and Paraiba, and is anchored by its flagship Sao Francisco copper-gold project.

Sao Francisco is the company's priority exploration asset, where historical drilling has defined a high-grade, copper-dominant mineralized system extending over approximately two kilometres of strike, with significant exploration upside along strike and at depth. Approximately 5,900 metres of historical diamond drilling has been completed, including intercepts of 7.50 metres (m) at 6.41 per cent copper (Cu) and 0.36 gram per tonne (g/t) gold (Au), and 7.53 m at 3.83 per cent Cu and 0.36 g/t Au.

Prospectiva will be undertaking a 2,500 m diamond drilling program in 2026, designed to infill key zones of high-grade near-surface copper mineralization and drill test key new conductive targets across the main three-kilometre Sao Francisco copper-gold project. The program is designed to support the definition of an initial mineral resource estimate (MRE) in 2027.
