Following the consolidation of project ownership to a 100% basis in August 2020 (see Calibre news release dated August 20, 2020), the Company initiated a comprehensive evaluation of EBP’s overall exploration and development potential. The work was completed by members of Calibre’s in-house exploration and technical services teams working in collaboration with external exploration and mining consultants. Key outcomes of the evaluation included firstly the recognition of the potential for further development of a high-grade open pit resource at the Guapinol and Vancouver deposits in combination with an underground resource at Riscos de Oro. A second outcome was the recognition of EBP’s significant potential for expansion of currently defined resources in combination with new discoveries on multiple other targets that have so far remained largely untested by exploration drilling.

The current drilling program includes 22,000 metres of infill, geotechnical and metallurgical drilling to support technical studies to evaluate development options for Guapinol-Vancouver and Riscos de Oro. The Company also plans to initiate a 7,500 metre exploration drilling program beginning in Q3 to test the potential to expand resources at Guapinol-Vancouver and Riscos de Oro, as well as first pass testing of high priority gold-silver targets along the principal structural trends in the district. During the past 11 years, a total of 40 kilometres of exploration and resource delineation drilling and 2 kilometres of surface trenching have been completed at EBP.

Between 2016 and 2019 drilling on five earlier stage targets intercepted high-grade gold-silver mineralization demonstrating further exploration upside that merits further follow-up. Highlights of previously reported drill results outside of current resources include:

Cadillac Zone: 2.6 metres Estimated True Width ("ETW") averaging 8.93 g/t Au and 57.4 g/t Ag between 65.6 and 69.7 metres down-hole in drill hole LS15-008;
San Cristobal Zone: 5.7 metres ETW averaging 10.92 g/t Au and 859.0 g/t Ag between 87.8 and 95.9 metres down-hole in drill hole SC18-002;
Veta Loca Zone: 5.4 metres ETW averaging 10.15 g/t Au and 6.9 g/t Ag between 88.8 and 94.3 metres down-hole in drill hole GP16-046; and
La Luna South Zone: 12.7 metres ETW averaging 5.75 g/t Au and 34.3 g/t Ag between 53.0 and 68.9 metres down-hole in drill hole LL18-012.
