Operations Updates: Bonanza Surface Sampling
Nativo Resources Plc has announced positive results from its Bonanza surface sampling program in Peru, confirming historical gold grades of up to 19.5g/t and averaging 10g/t, which support the company's plan to recommence gold production activities at Bonanza. The program, covering approximately 400 hectares and involving 20 trenches, has verified mineralisation along the Bonanza, Tesoro-01, and Tesoro veins, with identified structural controls favourable for mining operations. Discussions with contractors are underway to finalize the mine plan, with further sampling planned to refine the geological model and support the commencement of production. Disclaimer*

This confidence is underpinned by positive near-mine sample results and the successful completion of underground rehabilitation and preparation of existing mine workings. Additional prospectivity within the Tesoro Concession has also been confirmed.\n \nThe programme (completed and ongoing) covers approximately 400 hectares gathering approximately 250 samples. 20 trenches were excavated at 25-metre intervals to depths of 1.2-1.5 metres to expose the vein structures beneath the colluvial cover. Systematic channel sampling was completed within the surface trenches, with samples taken at 1-metre intervals across the exposed mineralised structures to characterise grade variability along strike. The sampling programme focused on geological mapping, trenching, and geochemical sampling, with the objective of verifying and augmenting the historical gold grades and locations originally identified by St Elias Mines (Figure 1), whose surveys were evaluating near-mine gold mineralisation and structural controls to support production planning and early-stage mining activities, and verifying the geological vein model.\n \nFor the Bonanza mine, Nativo's Qualified Person, who designed the ongoing underground mine sampling programme (over 150 samples) has reviewed the sampling and results available, including the St Elias...
