Pinnacle: 70 holes done, more to come!

Pinnacle Silver & Gold is now a long way into its underground drilling programme at the El Potrero project in Mexico. The company has already drilled more than 70 holes, and is looking to do more than a hundred before this programme is finished. The work will go a long way towards advancing Pinnacle's understanding of the project, which it hopes to put into production around the end of next year. Chief executive Bob Archer joins Vox to tell us more.
