Pinnacle Silver & Gold recently flew a LiDAR survey over its El Potrero project in Mexico with a view to identifying additional prospective areas. To date, the focus has been on old silver and gold workings to the north of the landholding. But following on from the LiDAR survey, Pinnacle has now identified significant silver, lead and zinc mineralisation further south. This type of mineralisation was previously unknown on El Potrero, and will now be the subject of follow-up work, including potential drilling in due course. Pinnacle's chief executive Bob Archer joins Vox to tell us more.
