BARKER BEGINS 2013 DRILLING AND TRENCHING AT FRANK CREEK VMS/GOLD PROJECT
Barker Minerals Ltd. has begun drilling on its 100-per-cent-owned Frank Creek volcanogenic-massive-sulphide project. Initial drilling will focus on the 2011 near-surface gold discovery area and follow up on precious-metal-rich VMS targets identified in past programs. The property is located in the Cariboo mining district of British Columbia, approximately 77 kilometres northeast of Williams Lake, B.C., and hosts excellent access and infrastructure.
FC-13-09 is a planned 200-metre to 300-metre hole being drilled within five metres from the collar of the shallow FC-11-03 (approximately 48-metre depth) in order to confirm the 2011 gold discovery as well as to test the underlying Titan trend C conductor for massive sulphide mineralization and to provide important geological information in the immediate 2011 gold discovery area.
Drilling in 2011 resulted in the discovery of a significant 22.45-metre-wide zone in FC-11-03 from 13.0 metres to 35.45 metres, which assayed 3.8 grams per tonne gold (0.11 ounce per ton). Within this zone concentrations of 4.95 g/t gold (0.14 ounce per ton) occurred over 14.95 metres from 13.0 metres to 27.95 metres. Narrow higher-grade intervals within the 22.45 metres include 41.4 g/t gold over 0.15 metre (1.20 ounces per ton) between 26.5 metres to 26.65 metres. The true width of the 2011 discovery gold zone is unknown at this time and is yet to be determined by follow-up drilling.
In gold-rich VMS systems, the higher-grade gold may be focused around the vent or feeder structures, which are typically faults or structures that extend to depth. The 2011 gold discovery at Frank Creek is indicative of close proximity to important vent or feeder structures, which was also confirmed by the numerous zones of precious and base metal mineralization, together with associated pathfinder and alteration minerals, intercepted in both the eastern portions of grid lines 55N, 57N, and the western portion of lines 51N and 53N. Mineralization in the VMS feeder zone consists of disseminations and stringer-type semi-massive to massive sulphides.
The focus of the 2013 VMS target drilling is the tracing and testing of near-surface to medium-depth targets identified from previous exploration programs, which exposed a broad zone of VMS footwall alteration associated with base and precious metal mineralization in an overturned geological environment. The highest gold grades in the drill holes to date are zoned immediately next to the VMS feeder mineralization, which is composed of base and precious metal mineralization similar to other gold-rich VMS systems. Frank Creek is also similar to other VMS gold environments in that it is spatially located in the immediate vicinity of historic placer gold operations.
The inverted VMS model
The overturned nature of the rocks at Frank Creek is supported by drilling, outcrop mapping and observations and studies conducted by the British Columbia Geological Survey (Hoy/Ferri, 1998) (Ferri/O'Brien, 2002) and independent company consultants. On most of the Titan grid, the large near-surface chargeability anomalies overlie or flank similarly large, strong conductive zones, which have a subsurface 3-D nature similar to that of massive sulphide bodies.
This geophysical association is also indicative of an inverted stockwork stringer or feeder zone overlying a potentially large massive sulphide deposit.
Historical surface trenching and exploration drilling on the Titan trend A and trend C conductors have confirmed a broad near-surface zone of VMS-style footwall mineralization (chargeability highs) and alteration, which is coincident with strong multielement enzyme leach soil anomaly patterns indicative of close proximity to the VMS feeder zone or vent. The soil patterns are similar to that intersected in the 2011 drilling.
The chargeability highs directly overlie large strong compelling conductors (resistivity lows), which are indicative of massive sulphide mineralization or graphite.
Gold-rich volcanogenic-massive-sulphide deposits
Gold-rich VMS deposits are an attractive worldwide exploration target due to the important precious and base metal content, as well as rarer byproduct metals like tin, indium, cadmium and bismuth.
Trenching and drilling at Frank Creek has exposed base and precious metal mineralization, which is associated with a rhyolite flow/dome complex and intermediate to felsic volcanic flows and tuffs. At Frank Creek the presence of rhyolite and bimodal volcanics, precious and base metal zonations, grades of metals, alteration patterns, and mineralogical associations are all indicative of a large precious-metal-enriched volcanogenic-massive-sulphide environment.
The favourable geological age of the host rocks, the local placer gold history, the broad overturned footwall target area, the large and strong near-surface Titan chargeability anomalies, together with the recent drilling discoveries of gold and silver, all bode well for the potential to not only discover important polymetallic VMS deposits, but discrete high-grade precious metal deposits within the much larger VMS hydrothermal system.
