Down Hole Geophysical Survey in First Hole Identifies Massive Sulphide Anomaly at Crowflight's AER/Kidd Property
|TORONTO, ONTARIO - CROWFLIGHT MINERALS INC.'s (TSX.V: CML) has completed a downhole transient electromagnetic (TEM) survey on the first core drill hole (W03-01) that intersected disseminated sulphide mineralization likely within a halo near a potential zone of massive sulphide (see press release December 5, 2003). This hole targeted an underground borehole (U09-23) completed in the mid 1960's near the AER-Kidd/Inco Totten boundary that intersected 1.3% Cu and 0.34% Ni over a core length of 30m (true width uncertain) at a depth of approximately 700m below surface. In addition, this borehole provided access for deep borehole electromagnetic measurements in an area where no previous geophysical data was available. |
Anomalous time domain electromagnetic responses were detected in borehole W03-01 from a depth of 700 meters to the end of the hole at 950 meters. The responses indicate an in-hole or near hole multiple conductor response typical of local stringer sulphide mineralization. A relatively strong off-hole, lateral response was also measured suggesting a massive or semi-massive sulphide body is in the vicinity of the hole and apparently beyond the hole. This response is likely coincident with the strong magnetotelluric (MT) anomaly centered on line 1200N which is being tested by hole W03-02 in progress as shown in Figure 1.
Mr. John Buckle, P.Geo., consulting geophysicist and the Qualified Person for the program commented: "There is a high probability that this target as well as the other geophysical targets outlined are massive sulphide bodies due to the nature of the response and the corrobating evidence from surface and borehole TEM, magnetic and magnetotelluric data."
The ongoing drill program will make maximum use of borehole transient electromagnetic surveying to systematically locate Totten-style massive sulphide bodies along the AER/Kidd Quartz Diorite offset which extends for 1 km along strike length on the property. This borehole technique effectively targets conductive bodies at the expected depths of 900 to 1100 meters. Drill holes have been planned, as shown in Figure 1, to test known MT anomalies as well as provide complete borehole TEM coverage along the full strike length of the AER/Kidd portion of the offset.
Consistent with our stated exploration program, we have now identified the massive sulphide anomaly and Crowflight will partially re-drill this first hole (W03-01) and realign it towards the massive sulphides. Crowflight is bringing in a third drill on January 5, 2004 to carry out this redrilling of the first borehole.
Core hole W03-03 in progress will test an MT anomaly on Line 1375N which appears to be the down plunge projection of the mineralization in the Robison zone. Figure 2 shows a plan map of the typical style of mineralization mined from the old workings. All mineralization occurs within the Quartz Diorite offset dyke with massive lenses of Ni-rich sulphide surrounded by Cu-rich stringer mineralization within a wider disseminated sulphide halo. This style of mineralization is similar to that present at the adjacent Inco Totten property.
Planned Hole W03-04 will test a strong MT anomaly on line 1550 which extends from about 200m below surface to a depth of 2000m. Hole W03-05 will test an anomaly which extends from surface to a depth of 1500m and that outlines the likely down plunge extension of the mineralization in the Rosen pit.
Boreholes W03-02 and W03-03 are presently at a depth of about 700m, and are scheduled to hit the planned geophysical targeted sulphide mineralization anomalies at a depth of about 1100m, see Figure 1. As in the first borehole (W03-01), Crowflight will use transient electromagnetic (TEM) survey in these holes to more accurately pinpoint the massive potential sulphide bodies.
The Company presently has two drills on the property, drilling boreholes W03-2 and W03-3. A third drill will be added on January 5, 2004. Crowflight expects to announce the results from holes W03-2 and W03-3 in the latter part of January 2004.
Crowflight Minerals is a Canadian junior mining exploration company listed on the TSX Venture Exchange. Crowflight is currently focused on two properties located in the Sudbury Basin: the AER-Kidd property is located on the Worthington Offset nearby Inco's Totten &McIntyre mines and FNX Mining's Victoria project. The Airport 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) hi-grade Cu-Ni-Co-PGM discovery near to the their past producer, Nickel Rim Mine.
