How Brigus Gold is Finally Making the Grade
Please enjoy my write-up from the recent return trip to Brigus' Black Fox mine near Timmins, Ontario
While it's tough to do in the context of these brief articles, I tried to get into the nuts and bolts of the guiding geological considerations between the 2 zones of the orebody.
"The Black Fox mine comprises two distinct ore zones that begged distinct approaches to mining activity. The West Zone is a "shear zone," where gold mineralization associated with vertical deformations in the host rock offers clearer visual guidance to miners and "beat geologists" navigating their daily ore excavations. The East Zone represents a "folded" geological structure that adds a measure of complexity and requires careful 3-D modeling to precisely guide mining activity."
In response to areader's prior question, they do indeed intend to meet Q2 guidance despite the interruption imposed by the nearby wildfires last month:
"Of the handful of active production stopes we visited during the tour, two of them were running in the neighborhood of 20 gpt (and contained visible gold -- see below). Incidentally, that pleasant fact may have contributed to Bilodeau's confidence that his team will still meet Brigus' second-quarter production target despite a multiday outage related to nearby wildfires last month. Brigus is looking for 18,000 to 21,000 ounces of gold production for the second quarter, with further volume improvements to follow on the path toward steady-state production rates by early 2013."
I hope you enjoy the images of the visible gold. The frequency of those occurences really does serve a timely reminder that for all the challenges endured to date, the quality of the underlying underbody has never come into question.
