Continental Gold Inc (TSX:CNL) (OTCQX: CGOOF) has dug up high grade samples from development cross-cuts and drifts at level 1B at the Yaraguá mine in Colombia.
Continental excavated 3.5m by 3.5m for 300m underground at level 1B, an area that may allow it to carry out more mechanised mining on the Yaraguá veins.
Mineralised intervals included 22m at 10.9 g/t gold and 25 g/t silver, 30m at 9.3 g/t gold and 26 g/t silver and 29m at 8.6 g/t gold and 23 g/t silver.
A new 3,000m underground drilling program is planned for the third quarter to target similar zones in the Yaraguá deposit.
"Underground development sampling at Yaraguá continues to deliver high-grade results over significant true widths," said Ari Sussman, Continental’s chief executive.
He added the sampling grades and previous long-hole trial mining test stope results indicated that the introduction of wider, more productive extraction methods on some areas was possible.
