Argent Minerals Limited (ASX:ARD) Kempfield Deep Diamond Drilling Program
The drilling program features a test of the area immediately to the west of the Kempfield deposit, where the Company has identified the potential for additional volcanogenic massive sulphide (VMS) mineralisation lenses and a high temperature feeder zone (Western Prospective Area).
Argent Minerals Managing Director David Busch said, "This will be the deepest drilling program conducted at Kempfield in over four decades of exploration. Financially supported by the NSW Government, this program will test the Western Prospective Area for additional higher grade base and precious metals in the interpreted feeder zone and mineralisation lenses, as well as for potential lens extensions at depth, underneath the existing Mineral Resource.
"Through a combination of advanced exploration techniques, and drawing on a range of industry best-practice expertise including the Company's in-house expert Dr. Vladimir David who has a track record in VMS deposit discovery, Argent has developed a comprehensive model of interpreted mineralisation that has not been detected by traditional survey techniques.
"Argent's exploration strategy includes a systematic approach based on a genesis model framework supported by geochemistry and an advanced geophysics program. The geophysics program combined the results of induced polarisation (IP) surveys and the more recent magnetometric resistivity (MMR) surveys, to provide a new and innovative method for the detection of lead zinc mineralisation at Kempfield. This has provided us with fresh insight into the potential mineralisation structures, which are now ready for drill-testing.
"Four holes will be drilled for a total length of 1,900 metres. The first two holes will be drilled toward the Southeast from locations adjacent the historic Colossal Reef copper mine. The first hole will be drilled to a length of up to 500 metres, and the second, the deepest hole in the program, will be drilled to a length of up to 650 metres. Together these first two holes will test the interpreted VMS feeder zone and Lenses 4 and 5.
"The third hole in the program will be drilled for a length of up to 350 metres to test the interpreted VMS Lenses 4, and the Northeast extension of Lens 3. A fourth hole will also be drilled for a length of up to 400 metres underneath the known mineral resource, to test for extensions of Lenses 2 and 3 at depth".
Figures 1 and 2 in link below set out the design of the drill hole plan designed to test the interpreted feeder zone and mineralisation lenses, where Figure 1 is a plan view against the MMR anomalies, and Figure 2 is a cross section.
The cross section in Figure 2 sets out the drill holes in relation to a diagram of the Kempfield genesis model and MMR anomalies that the holes are also designed to intercept as part of the test program.
About the diamond drilling program
In order to increase efficiency yet retain the benefits of diamond drilling, each hole will be drilled with reverse circulation (RC) 'pre-collars' that extend to a length of approximately 50-60 metres. Diamond 'tails' will then extended to approximately 100 - 150 metres at the larger HQ size in order to firmly establish the direction for each hole, before reducing to the smaller diameter NQ size for the remainder of each hole.
Hole 1 (500 m) will be drilled prior to the more technically challenging Hole 2 (650 m), in order to establish drill rig parameters for hole lift in this area of Kempfield geology.
Geophysics surveys will be performed on each hole, commencing with downhole MMR, which provided the clear response in the rich lead-zinc mineralisation section of the West McCarron hole AKDD159.
Downhole electromagnetic (EM) surveys will be performed in the Colossal Reef copper mine holes 1 and 2 to test for copper conductors.
Table A in link below summarises key drilling plan design parameters and the targets for each hole.

About Argent Minerals Limited:
Argent Minerals Ltd. (ASX:ARD) is an Australian publicly listed company with a 100% interest in a silver/gold project at Kempfield NSW. Work is underway on the preparation of an EIS and a feasibility study for the first stage of the project which will involve heap leaching some 8.8 million tonnes of mainly oxide and transitional material to produce over 9.5 million ounces of silver and 15,000 ounces of gold over a 5 year mine life. Argent is also earning up to a 70% interest in two other NSW projects - gold at West Wyalong and base metals at Sunny Corner.
