HEMLO GOLD PROJECT #1
Page updated March 27, 2017
NOT AVAILABLE FOR OPTION
This Project is currently under option to Sunvest Minerals Corp.
Other than Barrick - who doesn't appear to be exploring regionally - nobody else in the camp has the chance to test ground directly along strike of the open pit. Here is your opportunity. These claims fit perfectly into Barrick's "Go West" theme as outlined in their February 2017 Operations and Technical Update (link here); the two slides of interest can be viewed under the documents link on the right panel (slides 20 and 33; pdf report pages 23 and 36).
Two diamond drill holes on the northern "tongue" of the project intersect the Hemlo Shear Zone ("HSZ") and both have encountered broad intervals of anomalous gold in historic diamond drilling (>0.3 g/t Au over >10.0 meters) with locally higher gold values over 1.0 g/t Au. A closer inspection of the longitudinal diamond drill section (see it in the Maps section) reveals that there is ample room for a discovery hole within this portion of the HSZ. Both pierce points on the longitudinal section are relatively shallow at 190 meters and 320 meters vertical depth . Ground on either side of this claim is held currently held by Barrick Gold and has not undergone any significant exploration since the mid-to-late 1980's (a few drill holes in the 1990's). One well-placed drill hole could change the landscape significantly in the camp. A modified version of Barrick's Hemlo longitudinal section is provided for comparison purposes. Note the depth and orientation of the Hemlo ore body versus the depth of drilling and plunge to mineralization encountered on the Hemlo Project.
In addition to the diamond drilling there are also two surface showings reported to have assayed over 1.0 g/t Au separated by 17 meters along strike. A surface stripping program could greatly benefit the understanding of the HSZ and associated mineralization as well as provide for some good gold numbers along strike of the mine trend. Soil sampling from 1984 identified a sample assaying 0.42 g/t Au (see Maps section) in the area of the trenches re-enforcing the idea that significant gold mineralization may exist on the Hemlo Project waiting to be discovered.
In addition to the results mentioned above, a program of overburden drilling in the mid-1980's identified mafic-intermediate metavolcanic rocks south of the highway that has been mapped as granite by the OGS using geophysical inferences. This lobe of metavolcanic rocks may represent a new exploration target in the area.
Exploration Plans and Permits have been applied for and are pending.
The Hemlo Gold Project consists of 5 claim blocks covering a total of 24 claim units (384 hectares) in the Hemlo Mining Camp. The Project covers a portion of the Hemlo Shear Zone that is 6 kilometers west and along strike of Barrick Gold's current open pit operation with some of the Hemlo Project claim block being held by Barrick Gold (and previous operators) since the mid-1980's. A recent accidental lapse of mining claims by Barrick allowed for the staking of some of this ground with the additional ground recently added on to fill a wedge in the camp.
The Hemlo Camp has been heating up over the past year with numerous gold explorers staking and acquiring ground all around the producing mine(s) which have poured >22 million ounces to date. A large exploration program by Barrick has extended the mine life once again proving that undiscovered ounces still exist within this historic mining camp. Here is a link to a recent article by Canadian Orebodies summarizing some of the exploration in the camp.
Compilation map M2614 published by the Ontario Geological Survey titled "Geological Compliation: Eastern Half of the Schreiber-Hemlo Greenstone Belt" identified two surface gold showings and two gold intersections above 1.0 g/t Au in diamond drill core on the portion of the project covering the main portion of the Hemlo Shear Zone that is an on-strike projection of the mineralized mine-horizon.
While the geological maps of the area show the project as being underlain primarily by granitoid rocks of the Heron Bay Pluton, this determination has been made using geophysical inferences as the western portion of the project area is underlain by swamp with no outcrop. An overburden drill program by Tandem Resources Ltd. in 1985 showed that a mix of mafic-intermediate metavolcanic rock exists under the western portion of the Project with the highest assay from bedrock being 44 ppb Au. A follow up program of I.P. was recommended but not performed.
The Hemlo Gold Project has only had six (6) diamond drill holes on the property - all which have been drilled in the northern "tongue" of the property. An additional 17 overburden drill holes have been conducted on the lower east-west wedge of the project with all falling on the western side of the claim block.
As mentioned above, the overburden drilling intersected mafic to intermediate metavolcanics where the underlying non-exposed bedrock has been geophysically mapped as part of the granitic Heron Bay Pluton. The gold values intersected both on surface and in diamond drill core in the northern portion of the claim block demonstrate that the ground has potential to host significant gold mineralization.
The Hemlo Project is currently host to four mineral occurrences - three gold and one base metal. Two gold occurrences are from diamond drilling on the northern tongue that intersects the main portion of the Hemlo Shear Zone. In addition to the two gold occurrences discovered during diamond drilling, an outcropping exposure of sheared, altered and pyritic mafic-intermediate metavolcanic and Quartz Feldspar Porphyry (QFP) contact zone assayed 1.68 g/t Au and 1.47 g/t Au in areas 17 meters apart (Goldfields Powerline Occurrence). Other assays show grabs of 1.5 g/t Au in the area (see Maps section).
