Gravity West Identifies Potential Kimberlite, Uranium and IOCG Exploration Targets on Holland and Hogarth Properties in Northwest Territories and Nunavut

Gravity West Mining Corp. is pleased to announce that it has identified potential kimberlite, uranium, and IOCG (Iron Oxide Copper-Gold) exploration targets from the interpretation of the 2007 airborne geophysical survey data. The study was carried out by Condor Consulting Inc., who is specialists in airborne geophysical data interpretation. A total of 40 kimberlite targets, three unconformity type uranium targets, and two IOCG style mineralization targets were identified as a result of this study.

The 2007 airborne geophysical survey was conducted by Fugro Airborne Surveys (Fugro) over two of the company’s 100% owned properties (Holland and Hogarth) located in the Northwest Territories and Nunavut. The Holland Property is comprised of two claim blocks (Holland North and Holland South) covering an approximate area of 90,387.5 acres in 36 claims. The Hogarth Property is comprised of 19 claims covering an approximate area of 35,483.19 acres located in the Great Bear Magmatic Zone.

Typically, the kimberlites in northern Canada occur as inverted cone-shaped diatremes or pipes with diameters generally less than 400 m. Keating pattern recognition process which identifies circular magnetic anomalies was used to identify potential kimberlite targets. This method is widely used for diamond exploration.

For uranium and IOCG, the study identified groups of conductors, termed as Target Zones (TZ). The Target Zones were than prioritized based on overall geophysical characters, and their relation to the defined exploration model.

Details of the identified targets are provided in the following paragraphs.

Kimberlite Targets:

A total of 8 magnetic anomalies were identified on the Holland South area out of which six are positive anomalies and two negative anomalies. The negative anomalies are attributed to remnant magnetization in a direction opposite to the present magnetic field direction. Similarly, in the Holland North area, ten positive and two negative magnetic anomalies fit the Keating pattern recognition criteria. For the Hogarth Property, sixteen positive and four negative anomalies were interpreted to fit the pattern recognition criteria.

Unconformity Style Uranium Targets:

The Holland property is considered a favourable target area for Athabasca Basin unconformitytype mineralization due to the presence of Hornby Bay Group sedimentary rocks and the underlying basement belonging to the McTavish Supergroup. The Mountain Lake uranium deposit is located approximately 80 kilometres to the north of Holland Property.

In 2007 Fugro conducted a GEOTEM® electromagnetic and magnetic survey of the Holland North and Holland South claim blocks, collecting a total of 2,317 line kilometres data.

The present study identified two broad conductors TZ A and TZ B in the Holland South area, adjacent to which smaller, more discrete conductors were located. The TZ are mostly located in the northwest of the survey area underlain by rocks of the Hornby Bay Group rocks. TZ A and TZ B are interpreted as medium and weak wide zone conductors which generally lie at a depth of 200-400 m below surface. The smaller conductors are slightly deeper and possibly offset by faulting.

For Holland North area, one broad conductive area TZ C (12 x 8 km) was identified in the northwestern part of the property underlain by rocks of the Hornby Bay Group. Within TZ C two smaller, more discrete conductors (TZ C-1 and TZ C-2) were located where the conductivity is significantly greater than overall.

TZ A-1, TZ A-2 and TZ B-1 have been interpreted as priority 2 (medium priority) while and all other conductors are priority 3 (low priority) targets.

Iron Oxide Copper-Gold (IOCG) Targets:

The Hogarth property is considered favourable for IOCG type mineralization. In 2007, Fugro conducted a high-resolution magnetic and Gamma-ray Spectrometric survey on the property collecting 1,906 line kilometres data.

The interpretation of the geophysical data show a number of strong magnetic complexes which appears favourable for IOCG deposits, but there is a lack of strong, definitive radiometric signatures indicative of IOCG mineralization. The study also defined two, poorly defined IOCG Target Zones (TZ A and TZ B) out of which TZ B is partly located on the Hogarth Property.

Livio Susin, President of Gravity West, says: “The interpretation of our airborne survey data has provided a wealth of targets in a very prospective area, which has only seen cursory exploration in the past.”
