Work Plan

Defiance initiated a minimum 5,000 metre oriented core diamond drill program in December 2020 at San Acacio. The exploration and technical teams are improving drill targeting through mineral system understandings to define geologic and ore controls of the Veta Grande mineral system. Targets include blind and structural off-set zones for both resource expansion and exploration drilling in and around the Veta Grande vein. Ongoing field exploration programs are being conducted throughout the three project areas and include property-scale geological mapping and surface trace element geochemistry, relogging and additional analyses of existing drill core, and constructing 3D geologic and ore-control models. Future priority drilling areas are the Palenque structure at Lucita, as well as the Las Majadas zone on the Lagartos land package to follow up on prospective first pass drill results in an underexplored mineralized domain.
