Crowflight Updates Exploration Activity on its Sudbury Basin Properties
|TORONTO, ONTARIO - CROWFLIGHT MINERALS INC. (TSX Venture Exchange: CML) is increasing its exploration activities on its Sudbury Basin Properties (Figure 1 Location Map) with the addition of ground geophysical programs at the AER-Kidd property, and airborne geophysical surveys over its Airport Joint Venture and Marble Mountain Properties. Drilling at AER-Kidd remains on track with the focus on delimiting zones of semi-massive to massive sulphide mineralization similar to Inco's adjacent Totten Deposit within the Worthington Offset Dyke. |
AER-Kidd Property (100% Crowflight Minerals Inc.)
Crowflight has completed 7,000 metres of diamond drilling in 4 regular drill holes and 5 wedged drill holes for the Phase 1 program to date. Another 3 wedged holes are in progress.
Using the Totten Metallogenic Model (mineral resource of 10 million tonnes grading 1.4% Ni, 1.9% Cu and 4.7 g/t PGE's) as a guide, Crowflight has targeted its drilling to test five prominent Audiofrequency Magnetotelluric ("AMT") anomalies located at between 300 and 1,000 metres vertical depth along a 1.2 km segment of the Worthington Offset as shown in Figure 2. Drilling to these depths is time consuming and requires close monitoring with frequent use of wedges to ensure that targets are intersected at their intended locations.
DDH-WO3-03AW1, as previously reported (see press release February 8, 2004), returned a 35 metre wide (true width) sulphide zone which included a 9.8 metre true width semi-massive to massive sulphide segment grading 0.5% Cu, 0.8% Ni, 1.2 g/t Pt+Pd and 3.3 g/t Ag. This hole confirmed that the AMT and borehole Transient Electromagnetic ("TEM") surveys were very effective tools to outline zones of semi-massive to massive sulphide mineralization.
Since the press release, 4 more wedged holes have been drilled to test several broad AMT anomalies with assay results pending (refer to Figure 2). These holes intersected "halo-type" disseminated sulphides that are typically adjacent zones of more massive sulphides (refer to Figure 3). Assays are pending on two of the drill holes - DDH-WO3-04A (completed at 1,203 metres) and DDH-WO3-04W1 (completed at 1,190 metres); whereas DDH-WO3-2AW1 (completed at 1,524 metres) failed to reach the Offset Dyke, and DDH-O3-03AW2 (completed at 1,024 metres) intersected gabbro.
Off-hole TEM anomalies are present in all the drill holes, which indicates the potential for significant semi-massive and/or massive sulphides. These anomalies are currently being drilled via wedged holes. DDH-WO3-03AW4 is in progress at 400 metres and should intersect the intended mineralized target at around 800 metres; DDH-WO3-02AW2 is at 830 metres and should intesect the target at roughly 1,500 metres; whereas, DDH-WO3-04W2 is at 510 metres and should intersect the target at roughly 1,200 metres. Crowflight management expects that these wedged drill holes and required assaying should be completed in 4 to 5 weeks.
In addition, Crowflight is planning to complete several longitudinally oriented drill holes to better outline the shapes of the mineralized trends, as well as to provide for a broader exposure of offset dyke for the downhole TEM.
A ground AMT survey by Phoenix Geophysics Limited has begun over Perch Lake in the north-east part of the AER-Kidd property, to cover a 600 metre strike length of the Worthington Offset that was not previously surveyed. Once this survey is completed, complete geophysical coverage will be available for the entire Worthington Offset Dyke on the AER-Kidd Property, a distance of 1.8 km, from Inco's Totten Property, to the west, to its McIntyre Property, to the east. Anomalies identified in this survey will be drill tested in the Phase 1 program.
Airport Joint Venture Property (50% Crowflight Minerals Inc.; 50% Millstream Mines Ltd.)
The Airport Joint Venture property is located on the south-east rim of the Basin about 1.2 km east of Falconbridge's past producer, Norduna Mines and 4 km south-east of Falconbridge's recent Nickel Rim South high-grade Cu-Ni-Co-PGE's discovery (8 million tonnes grading 1.7% Ni, 4.5 % Cu and 5 g/t Pt+Pd), near their past producer, Nickel Rim Mine.
Geological mapping in the fall of 2003 revealed two significant Sudbury Breccia trends in the northern half of the property. The first is 100 to 150 metres wide and extends north-south for approximately 3 kilometres; whereas, the second wedges off the first and runs northwest for 1.5 km over the same width. Millstream completed induced polarization surveys (IP) over the northern part of the property that confirmed the geological interpretation. Crowflight plans to complete an airborne EM using the Megatem II system by FUGRO Airborne Surveys of Ottawa, Ontario to seek out potential massive sulphide targets at depth. Further follow-up ground geophysical surveys are planned followed by diamond drilling of significant anomalies.
Marble Mountain Property (Crowflight Minerals Inc. has an option to acquire 100%)
The Marble Mountain Property, located 30 km north-east of Sudbury in Parkin Township, hosts quartz diorites and sulphide mineralization that Crowflight believes is a previously unknown extension of the Parkin Offset. The Milnet Mine, a previous Ni-Cu-PGE producer, sits adjacent to the property. Surface grab samples from the property reveal grades up to 16% Cu, 0.06% Ni, 19 g/t Pt, 9 g/t Pd, 15 g/t Au and 377 g/t Ag.
The Phase 1 exploration program at the Marble Mountain Property is scheduled to begin in April 2004, and it will also consist of an airborne EM survey using FUGRO's Megatem II system, with follow-up field work consisting of detailed ground geophysical surveys, prospecting, geological mapping and sampling to confirm targets for diamond drilling.
Crowflight's exploration team in Sudbury is led by Peter Karelse, Exploration Manager, with over 15 years experience in Sudbury and Sudbury-type mineralization, under the supervision of Jean Lafleur, P. Geol., VP Corporate Development, with over 20 years experience in mineral exploration, including at the corporate and senior management levels, and is Crowflight's Qualified Person as defined under National Instrument 43-101.
