Mountain Boy Minerals Ltd. (MTB.V) is a Canadian mineral exploration company with a diversified portfolio of properties in the Golden Triangle of British Columbia. They focus on strategic acquisition, resource advancement, joint ventures, and asset monetization to maximise shareholder value. This week we are focussing on their American Creek property, which is currently being prepared for drilling. I had a chat with Lucia Theny, VP of Exploration, as she waited for the weather to cheer up to begin her day at their exploration camp in BC.

American Creek is one of 5 projects and refers to a 2,602ha large-scale property prospective for epithermal precious and base metal deposits, intrusion-related gold-silver deposits and porphyry copper-gold deposits. The district is divided into 3 main target areas: Mountain Boy Silver Mine, Dorothy, and Wolfmoon, of which the former is 100% owned and the others have an option to earn 100%. Their mineral potential is summarised in Table 1.

The upcoming drill program will test 3 targets: Mountain Boy mine, Dorothy, and the Wolfmoon Zone.

Drilling at the Mountain Boy mine is to follow up on assays returned in 2006 showing 5.2kg of Ag in 5m. The objective is to delineate continuity and the extent of the high-grade mineralisation along strike and at depth. Veins present here contain Ag-Pb-Zn + Au and have returned some incredibly high silver grades (Table 2).

The Dorothy target area has never been drill tested before and has potential to demonstrate significant size potential of the mineralised system. The veins here are interpreted to be part of the same mineralisation system as the historic Mountain Boy mine, which is 2km away, the system that is driven by the American Creek intrusion.

The third drill target, the Wolfmoon Zone, was only discovered last year and is already being prepared for drilling. To go from discovery to drilling in one year is quite unusual and the zone has potential for some exciting geological discovery. MTB have deployed a dedicated mapping team to puzzle out whether or not Wolfmoon is sitting over a volcanic centre. The property reflects the diversity of the American Creek project, as it represents a younger phase of mineralisation that is distinctly different from Dorothy or MB mine. A ground induced polarization geophysical survey (IP survey) has recently been completed on this target.

The diversity of mineralisation, proximity to nearby historical mines, as well as promising grades all contribute to MBM’s confidence in their flagship American Creek project.

Mountain Boy Minerals are not just focussing on American Creek this year, however. Their BA and Surprise Creek properties both host large silver VHMS targets. The former is being mapped by abseiling geologists (worst job in the world…) who are on the hunt for mineralisation (Figure 2).

Lucia’s excitement about the geology of the area was infectious, and rightly so. Not only are MTB establishing a comprehensive geological understanding and finding some cracking rocks, they have an exciting few months of exploration and (hopefully) results ahead.
