Gordon Lake Project
Description and Location
The Gordon Lake Property is located at the north end of Gordon Lake approximately 115 kilometers north-northeast of Yellowknife Northwest Territories, in the Mackenzie Valley Mining District and consists of four mineral claims that surround Mining Lease 3123. The property is currently held by Boxxer Gold Corporation and is under option to Champlain Resources Inc.The property covers 6632.8 acres centered about 2200 meters north of Gordon Lake at an approximate elevation of 340 meters. The property covers Ven Lake, a smaller lake east of Main Zone. The past producing Burnt Island and Camlaren Mine are located on the eastern shore of Gordon Lake approximately 25 and 36 kilometers south-southwest of the property respectively.
Property topography is low and consists of many small but steep approaches to bedrock exposures.
Access is by helicopter and ski- or float-equipped aircraft in the winter or summer. A maintained winter road, which traverses Gordon Lake to service the diamond mines to the north, is commonly operational from the third week in January to the third week in March. This winter road traverses through the eastern portion of the property and provides truck accessibility during the winter road season. A 3 kilometers long bush road joins the Main Zone with the winter road.
Known Gold Structures
The property is host to a minimum of seven auriferous quartz veins that occur over a 1.0 kilometer strike length.These auriferous quartz veins are considered to be Coarse Gold-bearing Veins and lie within the Yellowknife Group Burwash Formation of greywackes, argillites and mudstones. There is a prominent shear zone which cuts the sedimentary package in a northeasterly trend which hosts the auriferous quartz veins. Most of these veins are only traceable at surface for a maximum of 100 metres, although more extensive strike lengths have been documented. These auriferous veins have highly variable gold concentrations both laterally and vertically. They occur as veins or stockwork that pinch and swell producing dilatant zones of quartz material that are prominent for up to 40 metres. Most of the significant gold concentrations appear to be in the hanging wall portion of the vein but do occur within the core of the vein.
The majority of the exploration results and the resource estimates are historical. Diamond drilling has delineated three prominent zones of mineralization, the Main, South and Union. Documented intersections show limited continuity, inferred to be primarily due to the style of mineralization and the lack of sampling or high definition drilling.
The W1 Vein (Main Zone) has a conceptual estimated resource of 12,500 tonnes grading 10.3 GMT gold to a depth of 15 meters*. Indications are the zone may well continue to depth both north and south. Drilling suggests the continuity of this zone may not extend below this level but higher definition drilling in the area to the south may well extend this resource.
The #9 Vein (South Zone) has spectacular intersections of gold mineralization to 205 meters depth. One intersection returned a grade of 17 g/t Au over 7.0 meters. Of significant interest are the high-grade ore shoots of mineralization that occur throughout the vein system. Conceptual resource calculations on the #9 Vein are speculative and should not be relied upon. In-fill, high definition drilling needs to be undertaken to properly assess the resource potential of the #9 Vein. Modeling of the historic results and the three holes completed in 2005 indicate that a larger high-grade gold zone rakes steeply to the south-southeast.
The S3 Vein, part of the South Zone, has been intersected with five drill holes. All drill holes have returned auriferous intersections grading up to 8.2 g/t Au over 2.0 meters.
The Union Zone has only been tested with ten drill holes. Surface channel sample assays are up to 8.35 GMT gold over 6.1 meters. Diamond drilling has returned grades up to 3.77 GMT gold over 6.4 meter core length.
These three zones have been the focus of the most intense exploration on the property. The geophysics competed to date does not appear to be a tool that is helping with the delineation of additional targets.
Induced polarization and total field magnetic surveys need to be completed over these three prominent zones in order to provide a systematic evaluation for other surface targets.
Other surface targets have been delineated through previous work. Some of these targets are the Camp, Road, Navel, BLT and Syn Vein. Limited channel and trench sampling has been undertaken on most of these veins.
Historic Gold Resources and Past Exploration
The area was subject to prospecting and sampling in the 1940's by Cominco Ltd. Sporadic exploration took place during the 1970's and significant exploration programs were conducted in 1983, 1987-1988 and 1994. Surface trenching, mapping, prospecting, sampling, ground and airborne geophysics, tonnage calculations and significant drilling have all been completed.Drill indicated non-NI 43-101 compliant historical inferred possible resource estimates have been established for the W1 Vein and the #9 Vein in 1988 (Balog, 1989). This estimate was completed using a 4.0 GMT gold cutoff over a minimum width of 1.5 meters (true width) and a specific gravity of 2.7 tonnes per cubic meter. The W1 Vein is estimated to contain 12,500 tonnes grading 10.3 GMT gold and the #9 Vein is estimated to contain 106,500 tonnes grading 11.3 GMT golf. A higher grade section within the #9 Vein is estimated to contain 60,700 tonnes grading 17.8 GMT gold. These calculations are taken from Balog (1989) but not confirmed. All resource estimates are calculated using longitudinal sections of the veins and a polygonal block method. Polygons have included all material to the midpoint between adjacent holes. Polygons occurring on the edge of the longitudinal and having no adjacent holes were extrapolated a maximum of 15 meters.
The Historical Estimates were not prepared by independent Qualified Persons, nor has any of the information contained therein been audited by an independent Qualified Person. The Historical Estimates do not conform to the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) standards of reporting pursuant to requirements under National Instrument 43-101.
No original data exists aside from hand drawn drill sections and partial assay data which cannot be correlated to individual drill holes. It should be noted all previous reports were written by independent third parties with no direct benefit from the property. A total of 81 diamond drill holes have been completed on the Gordon Lake Property. All of this information is contained on hand drawn sections. The drill logs are missing as are most of the maps. The assay data is available from the 1988 drilling (holes 36-81) and the 1994 surface program which allowed for verification of a significant portion of the 43-101 report. Diamond drilling conducted in 2005 is digital. Historic drill results have been digitized to the extent possible an incorporated in to the 2005 dataset.
In the summer of 1983, Newcan completed gridding, surveying, mapping, geophysics, geochemical soil sampling, prospecting and trenching. An additional 1,094 meters of diamond drilling in 20 holes tested the No. 1 vein Main Zone and the newly discovered South Zone located 350 south-southwest of the Main Zone. Trench samples that assayed up to 87.3 g/t gold were obtained in the South Zone. Newcan completed a total of 1,489 meters of drilling in 35 holes on both zones. The maximum grade intersected by the drilling was 67.9 g/t over 2.0 meters. Of the 28 holes completed on the No. 1 vein Main Zone in 1983, 12 returned assays greater than 10 g/t gold. Four of the seven holes completed on the South Zone returned greater than 10 g/t gold.
In 1987, Pacific Trans Ocean Resources Ltd. acquired a 100% interest in the Property. In 1988, surface exploration and diamond drilling programs conducted by Aurum Geological Consultants Inc. on contract to Pacific Trans Ocean led to the discovery of the high-grade gold mineralization in the No. 9 vein, the Union zone and the Camp vein. A total of 5,261 meters of drilling was completed in 47 holes.
PROPERTY GEOLOGY
The Gordon Lake property is situated along the eastern edge of a rift-like basin bounded by mafic volcanics (Figure 15). The basin is characterized by Burwash Formation metasediments comprising a sequence of interbedded greywacke, argillite (pelite) and graphitic mudstone. Beds vary in thickness from millimeters to several meters with the wackes forming the thickest layers. It is very common to see primary features preserved. This is a classic turbidite sequence. The eastern portion of the property is underlain by pillowed basalt and andesite belonging to the north-south trending Cameron River Formation. Pillows/pillow selvages are common and distinctively stretched. Plagioclase laths are very common in the groundmass and local concentrations of magnetite provide a weak magnetic signature.Quartz-mica schist and amphibole-mica schist usually help delineate deformation zones within the sedimentary and volcanic terranes, respectively. Dacite occurs as isolated plugs and thin tabular bodies while limited rhyolite exposures usually occur as fine-grained to aphanitic flow banded ash tuff horizons.
Structural trends across the property are coincident with the regional ones (N60°E and N20°W). Metasedimentary units commonly trend at 010° or 040° and dip steeply to the southeast. It is the pelite and mudstone units that have been the focus of deformation. Commonly these units are contorted, drag folded and sheared and likely have acted as the locus for thrust faulting. This deformation provides the necessary structural thickening of quartz veins and thus is the preferred host for these mesothermal veins.
