Successful 2011 Drill Program Advances Sisson Project Feasibility Study
|November 30, 2011 Vancouver, BC -- Northcliff Resources Ltd. ("Northcliff" or the "Company") (TSX-V: NCF) announces the successful completion of its 2011 drill program at the feasibility-stage Sisson Tungsten-Molybdenum Project, located in west-central New Brunswick, Canada. Geological and engineering drilling undertaken this year have significantly advanced feasibility-level data acquisition on the project.|
"Sisson has been the focus of considerable exploration and delineation drilling in the past, such that a great deal is known about the tungsten and molybdenum mineralization within the known Sisson deposit," said Chris Zahovskis, Northcliff President & CEO. "We are confident that the 2011 drill program will significantly expand our geological knowledge of the resource, while completing the technical database necessary to finalize a Feasibility Study for the Sisson Project next year."
The Sisson property hosts a large near-surface tungsten-molybdenum deposit with mineral resources potentially amenable to open pit mining. Northcliff is advancing feasibility-level geology, engineering and environmental studies, along with associated fieldwork and comprehensive stakeholder engagement programs, toward the completion of a Feasibility Study and Environmental Impact Assessment (EIA) for the Sisson Project in the third quarter of 2012.
The recently concluded drill program at Sisson totaled 8,482 metres in 61 drill holes and focused on the collection of:
Metallurgical holes were designed to obtain material that is representative of the styles of mineralization, types of host rocks, and tungsten and molybdenum grades within the Sisson deposit, as established by existing three-dimensional geology and resource estimation models. The average weighted grade of significant intersections reported here is 0.106% WO3 and 0.025% Mo. These results compare favourably with the average grades of 0.094% WO3 and 0.031% Mo contained within the 43-101 compliant estimate of 177.4 Mt of measured and indicated resources (see Northcliff News Release dated June 7, 2011)1.
Further information on the 2011 drill holes and their locations can be found at the Company's website at www.northcliffresources.com.
1Reported at a 0.100% WO3 equivalent threshold using metal prices of US$9/lb for WO3 and US$15/lb for Mo and recoveries of 70% for WO3 and 85% for Mo.
The objectives and types of data obtained from the non-metallurgical drill holes are described below. Analytical results for non-metallurgical holes are pending.
Twelve hydrogeology drill holes were completed at six sites around the project area boundary. Piezometers were installed in 11 of these holes to obtain baseline information on subsurface hydrological conditions. Glacial overburden was drilled by auger, while PQ-diameter (85 mm) core was obtained from bedrock. All hydrogeology holes were drilled vertically at depths ranging from 8.0 to 39.6 metres.
A total of 17 engineering holes were drilled at Sisson in 2011 to assess ground conditions in areas of potential infrastructure development. Glacial overburden was drilled by auger, while HQ-diameter (63.5 mm) core was drilled in bedrock. Standard penetration tests (SPTs) were completed in all drill holes, with samples obtained for sieve and other analyses. Engineering holes were drilled vertically at depths ranging from 23.0 and 50.5 metres.
Oriented HQ-diameter core was drilled in seven angled holes to depths of between 201 and 321 metres for pit wall stability and hydrogeology studies. Orientations were obtained with the Reflex ACT II RD core orientation tool. Samples were collected to conduct uniaxial compressive strength (UCS) and direct shear (DS) tests.
Finally, 10 angled holes of between 129 and 507 metres in length were drilled to test for extensions of the Sisson deposit mineralization at depth, and to further delineate the margins of the current estimated resource model. Tungsten and molybdenum mineralization was identified visually in each of these holes, but the significance of these geological observations cannot be assessed pending receipt of analytical results.
Dr. James Lang, P.Geo, a Qualified Person as defined by NI 43-101, supervised the 2011 exploration and quality assurance and quality control programs on behalf of Northcliff and has reviewed the technical content of this release. Geological logging and sample preparation was completed by Northcliff personnel under the direct supervision of Dr. Lang. Knight Piesold Consulting of Vancouver, British Columbia assisted Northcliff with geotechnical logging and sampling during engineering, hydrogeology and oriented-core geotechnical drilling.
Northcliff is a mineral resource company associated with Hunter Dickinson Inc. (HDI), a diversified, global mining group with a 25-year history of mineral development success. Northcliff is focused on advancing the feasibility-stage Sisson Tungsten-Molybdenum Project, located in New Brunswick, Canada, to production. Northcliff has acquired a 70% interest in the Sisson Project from Geodex Minerals Ltd., subject to investing up to $17 million in exploration, feasibility and project costs.
The advanced stage Sisson Project has excellent potential for near-term production of tungsten and molybdenum. Its location near roads, rail and tidewater on the eastern seaboard of North America provides Sisson with key logistical advantages over its peer group. New Brunswick is a stable jurisdiction with a long tradition of mineral and resource development, and a well-established regulatory system. By advancing Sisson, Northcliff will become one of North America's first major tungsten producers, greatly increasing supply to the large North American and European markets where demand far outstrips supply.
