NORTHERN LIGHTS PROJECT
MINERAL COUNTY, NEVADA EXECUTIVE SUMMARY |
Summary: Northern Lights is situated in proximity to two major gold producing districts, Aurora (0.6 million ounces gold) and Borealis (1.2 million ounces gold). Bonaventure controls approximately two square miles of unpatented claims hosting a nearly 10,000 feet long mineralized shear zone. The zone outcrops in limited areas, but surface sampling to date shows gold values up to 0.175 oz/ton gold. Previous drill holes have all been vertical. This drilling intersected significant thicknesses of low grade gold. The property has strong potential to host both a Borealis type bulk minable, heap leachable deposit and Aurora type high grade veins. Detailed geologic mapping, geochemical sampling, geophysics and angle drilling are planned. Location: The Northern Lights property is located approximately 150 miles southeast of Reno in Mineral County, Nevada. Access is via 17 miles of paved and 13 miles of dirt roads from Hawthorne, Nevada. The Northern Lights claims are situated between the Aurora (0.6 million ounces gold) and Borealis (1.2 million ounces gold) historic mines. Land Status: Bonaventure presently controls the property via 63 unpatented mining claims or approximately 1,260 acres.. |
| Geology and Mineralization: The Northern Lights northern target is developed within a Cretaceous age granitic intrusive Vein zones are composed of calcite, coxcomb quartz and opaline silica in float trains and subcrop. These zones have seen little physical work. A northwest trending fault appears to control mineralization. The southern target consists of a 150 feet wide zone of bleached and silicified volcanics. Drilling by Western Mining in the sand and gravel covered area between the north and south targets found that they are connected at depth. The combined length of the mineralized structure appears to be nearly 10,000 feet. Metallurgy: No metallurgical work has been completed on the property. However, oxidized portions of the Aurora and Borealis mineral deposits leached at +90% in three days (0.1 to 0.3 oz/ton gold in tabular to steeply dipping ore deposits). It would be reasonable to expect similar recoveries from any oxidized mineralization at Northern Lights Ridge. Targets: The Northern Lights property contains two distinct and separate types of mineralization. Quartz-calcite veins with coxcomb structures (boiling texture) in granite occur in the northern target while a broad zone of silicified volcanics occur in the southern target area. Previous drill holes have all been vertical. The high-grade vein target represented by the northwest trending shear zone that crosses the entire property has never been tested. Testing of potential ?feeder? faults should be carried out with angle drilling. Potential exists for both Borealis ?blanket type? (1.2M oz gold) and Aurora high-grade vein type deposits (0.6M oz gold). |
History: Tenneco Minerals was the first to explore the property in the early 1980?s while looking for extensions of their Borealis gold deposit. Exploration drilling started in 1982 with at least 8 holes by Tenneco. Several intercepts ranged from 10 to 45 feet grading from 0.02 to 0.045 oz/ton gold. Surface sampling from vein-float material assayed as high as 0.175 oz/ton gold. Westley Mines drilled an additional three holes on the southern portion of the claim group with similar grades and thickness. Western Mining explored the property in the late 1990?s drilling at least 12 wide spaced holes through alluvial cover. Reported intercepts (Western Mining staff) of up to 200 feet of low grade gold under alluvial cover were not followed up. These intercepts indicate mineralization extends under cover and connects the northern and southern target areas. Recommended Program: Detailed exploration will be conducted for the entire project area at a scale sufficient to define the location and attitude of all vein and altered areas. Additional rock chip geochemical sampling of all identified target areas will be carried out. Geophysical surveys are planned to further define this poorly outcropping mineral system. Trenching or shallow geochemical drilling in shallow covered areas may also be useful. Ten angle RC holes are planned project wide. The above work will be completed in approximately12 months.
