SPRUCE RIDGE RESOURCES BEGINS DRILLING THE CRAWFORD PROPERTY
Spruce Ridge Resources Ltd. and Noble Mineral Exploration Inc. have begun drilling on its optioned property in Crawford township, Ontario. The diamond drill program will be approximately 2,000 metres.
The first drill hole is planned to be 600 metres deep and will test the strongest portion of a 3,000-metre-long magnetic anomaly within an interpreted ultramafic and mafic intrusive complex covering an area of approximately 3.5 by 2.0 kilometres, estimated from recently completed airborne geophysical surveys. An airborne gravity survey using the Falcon system was recently carried out by Noble Minerals Inc., the optionor of the Crawford property. A helicopter-borne electromagnetic and magnetic survey also covered the area.
The presence of ultramafic and mafic intrusive rocks is confirmed by limited diamond drilling performed in the 1960s. Ultramafic-mafic complexes are favourable sites for nickel plus or minus copper plus or minus cobalt plus or minus platinum-group elements (PGEs). The primary target of the upcoming drill program is a magnetic anomaly peak and closely associated 1,400-metre-long EM conductor. An artificial intelligence (AI) assessment of combined geological and geophysical data confirmed the favourable interpretation of the ultramafic-mafic intrusive complex as a target for nickel mineralization, as well as highlighting VMS-type targets elsewhere on the Crawford property (see news release of July 16, 2018).
The Crawford property is crossed from south to north by provincial highway 655. The target area is 42 kilometres by road from the centre of Timmins and it is 17 kilometres north of the Kidd Creek zinc-copper-silver mine, which has been in continuous operation for 50 years, producing in excess of 100 million tonnes of ore, making it one of the largest VMS mines in Canada and in the world. The Timmins mining camp has produced more gold than any other mining district in Canada, over 70 million ounces to date. Gold mining commenced in 1909 and continues today, with new discoveries being made in response to new exploration programs. The target area for the present drilling program is within 1,500 metres of highway 655.
Despite being so close to a major mining camp, the Crawford property has seen relatively little historical exploration. It is in the Abitibi Clay belt; outcrops are essentially non-existent, making conventional prospecting impossible. The clay and till cover is up to 60 metres thick, and the clay interfered with early electromagnetic survey systems, creating false anomalies and distorting bedrock conductive responses so that anomalies often appeared in the wrong place. Modern electromagnetic methods have largely overcome the clay effects and enable definition of drill targets under thick overburden. Magnetic and gravity surveys are also unaffected by clay and have played a major role in defining the current exploration targets.
