Additional Diamond Drill Results in Tinta Zone Confirm Extension of Vein System to Depth and Along Strike
Vancouver, BC: September 10th, 2007. Northern Freegold Resources Ltd. (NFR: TSX-V) is pleased to announce additional drill results from the 2007 diamond drill program at the Tinta Zone of the Freegold Mountain Project, Yukon. The Tinta Zone is located in the eastern area of the 166 square km district scale project, approximately 20 km from the Nucleus Zone. The Tinta Zone appears to be an intrusion hosted polymetallic vein deposit, which are often found associated with porphyry style mineralization.
Highlights of Drilling at Tinta Zone:
Historical work on the Tinta Zone identified a steeply dipping vein system over a strike length of 3500 m (11,480 feet). Seven hundred metres (2,300 feet) of the system had been trenched and tested by shallow drilling (maximum depth 160 m (525 feet) from surface, as well as 939 m (3,080 feet) of drifting on two levels. Following Northern Freegold's goal of "developing resources, building reserves", the focus of the 2007 drill program at the Tinta Zone, was to test the extension of the Tinta Vein system to depth, in an effort to determine potential for expanding resources in the zone. Hole TH07-08 intersected massive sulphide mineralization including pyrite, chalcopyrite, galena, and minor sphalerite (with values in gold and silver) in the Tinta Vein at a depth of 225 m (738 feet) (refer to attached plan map and section)
- Hole TH07-08 returned 1.7 m (5.58 feet) of 14.90 g/t (0.435 oz/t) gold, 446.00 g/t (13.00 oz/t) silver, 3.3% copper, 5.2% lead and 0.66% zinc (previously released)
- Hole TH07-08 intersected the near vertical Tinta vein at a depth of 225 m (738 feet), extending mineralization 100 m (328 feet) down dip from the deepest pervious intercept
- Hole TH07-07, drilled at a steeper angle from the same set up at TH07-08, intersected the vein a further 100m (328 feet) down dip and returned 0.74 m (2.42 feet) of 7.20 g/t (0.21 oz/t) gold, 97.6 g/t (2.85 oz/t) silver, 0.92% copper, 0.54% lead and 2.17% zinc
- Hole TH07-11 stepped out 50 m to the southeast from the collar of TH07-08 & 07 and intersected the vein at 246 m ( feet) and returned 1.32 m (4.33 feet) of 8.92 g/t (0.26 oz/t) gold, 356.23 g/t (10.40 oz/t) silver, 1.17% copper, 3.41% lead and 4.22% zinc
- Hole TH07-12 stepped out 50 m to the northwest from the collar of TH07-08 & 07 and intersected the vein at 233 m ( feet) and returned 1.10 m (3.61 feet) of 8.23 g/t (0.24 oz/t) gold, 134.00 g/t (3.91 oz/t) silver, 1.61% copper, 1.91% lead and 2.35% zinc
Hole TH07-07, which was drilled at a steeper angle from the same set up at TH07-08 intersected the vein system for 11 m (36 feet) with a true width 6.1 m (20 feet) at a depth of 318 m (1,045 feet). A higher grade section (0.74 m) within the vein system returned 7.20 g/t (0.21 oz/t) gold, 97.6 g/t (2.85 oz/t) silver, 0.92% copper, 0.54% lead and 2.17% zinc. Strong sulphide mineralization included tetrahedrite, chalcopyrite, galena, and sphalerite in vuggy quartz/carbonate veins. Drill hole TH07-07 has doubled the known vein depth to 300 m (984 feet.)
Holes TH07-11 & 12, stepped out 50 m (164 feet) to the southeast and northwest of the collar of holes TH07-07 & 08, and intersected the Tinta Vein at depths of 245 m (804 feet) & 233 m (764 feet), again confirming the extension of the Tinta Vein at depth, and along the structure as well.
Slickensides and remnant clasts of ore material in the drill core indicate the Tinta Vein System has experienced more than one phase of mineral deposition. Post Cu-Pb-Zn-Ag ore deposition faulting along the Tinta vein created a brecciated zone within the vein system where later pulses of mineralizing fluids coupled with other tectonic activity are thought to be responsible for the high grade gold values. Whether the mineralizing fluids responsible for this second phase gold deposition are restricted to the Tinta vein is being investigated further, and may have positive implications on overall exploration potential on the Tinta and other zones within the Freegold Mountain Project. A Ph.D. student under the supervision of Dr. David Lentz, Associate Professor in the Department of Geology at the University of New Brunswick is studying the controls on mineralization at the Freegold Mountain Project.
Bill Harris, President & CEO commented "The continuation of the high-grade values within the Tinta Vein System at depth and along strike has tripled the potential size of the mineralized system at Tinta, which is still open in all directions. These results reinforce our belief that this system, although different in type and mineralogy to the Nucleus Zone, will enable us to fulfill our purpose of developing resources and building reserves in multiple deposits within the district scale Freegold Mountain Project Area."
The Freegold Mountain district scale Project covers an area in excess of 64 square miles (166 square km) and several road accessible mineralized zones which include historical and non-43-101 compliant resources. Historical work on the property dating back to 1930 indicates that the property holds significant potential to host an intrusion related gold deposit or bulk-tonnage gold+/-copper porphyry style mineralization (ie Nucleus Zone) such as that seen at Kinross Gold's Fort Knox deposit in Alaska which has produced more than 3 million ounces in the past 10 years and still has a resource of 2 million ounces of gold from proven and probable reserves of 82.1 million tonnes grading 0.74 g/t. The Project also has potential to host other related deposit types such as intrusive hosted polymetallic vein systems (Tinta Hill), epithermal vein systems (Goldy) and skarn deposits (Margarete/Augusta), as well as other porphyry targets (Castle, Com, Nitro, Rage).
Quality Control and Assurance
All core samples from diamond drilling are split and sent to EcoTech Laboratory in Whitehorse for sample preparation and then to EcoTech Laboratory in Kamloops for analysis. Blanks, commercial standards and duplicate core samples are included in each batch. Gold is analysed on 30 gram pulps by fire assay followed by aqua regia digestion and Atomic Absorption Spectrometry (AAS). Gold values greater than 1000 ppb are reanalysed by gravimetric fire assay. Check assays are carried out by metallic screen fire assay. Other elements are analysed by 28 element ICP analysis after aqua regia digestion. Additional check analyses and assays will be carried out by ALS Chemex in North Vancouver.
The program is under the direct supervision of Mr. Ron Robertson, P. Geol., hereby identified as the "Qualified Person" under the NI 43-101 requirements.
Northern Freegold is a Canadian-based resource exploration and development company which relies on local expertise and strong management to focus on development of economic reserves on the district-scale Freegold Mountain Project in the Yukon and the Burro Creek Project in Arizona.
