As reported in the Bulletin in October, a new company, Kootenay Zinc Corp. was formed to take over drilling on the Sully project near Fort Steele. Three drill holes, with a budget of $500,000 were planned, as the search for a Sullivan Mine style SEDEX deposit continues.
The latest update from the drill program is that drilling on hole SY16-10 has been suspended due to new results in gravity modelling and observations made of the geology intersected in the hole.
Drilling on the hole was progressing well but, as the hole deepened, three things became apparent, says a company press release.
Modelling of the current gravity data set suggests the target is much closer to surface than previously defined and has an apparent east dip of about 60 degrees to the east. SY16-10’s trajectory would have missed this new understanding of the target geometry.
Geological information, both from mapping and drilling, shows that strata are folded with dips from steep east to steep west and faulted such that, with depth, offsets are progressively farther east.
The overall effect produces an apparent uniform 60-degree-east dip to the gravity field.
A fault at 242 metres in SY16-10 appears to be a low-angle, west-dipping normal fault that offsets the stratigraphy (and therefore the target) such that the target is probably farther east at depth than originally thought.
Based on these observations, the project team elected to suspend deepening of hole SY16-10; however, it can be re-entered in the future if required.
Applications for new permits have recently been filed with the Ministry of Energy and Mines for several new drill collar sites that will allow for effective testing of the newly defined East anomalies. Drilling is planned to resume in early 2017 after the holiday break and updates will be provided at that time.
Two other mass anomalies also warrant further investigation and Excel Geophysics Inc. has mobilized on the site to do additional surveys.
