NORTHERN TIGER RESOURCES IDENTIFIES ADDITIONAL GOLD ZONES AT 3ACE AND PROVIDES UPDATE ON YUKON EXPLORATION PROGRAMS


Four separate gold-bearing zones have been identified on Northern Tiger Resources Inc.’s 3Ace property in the southeast Yukon, Canada. In addition, initial drill results from the Sonora Gulch property in the Dawson Range area of the central Yukon have verified the existence of an underlying porphyry system.

“We are excited to announce that Northern Tiger’s initial exploration program at the 3Ace project is continuing to demonstrate its high-grade gold potential. We expanded the strike length of the high-grade discovery vein to over 50 metres before it disappears under heavy overburden. Significantly, initial exploration results have now identified four gold zones in a two-square-kilometre area, each returning at least one-ounce-plus gold assay. Visible gold has been noted in three of the zones,” says Greg Hayes, president of Northern Tiger. “The drilling program at Sonora Gulch has also met its primary objective of verifying that a porphyry copper-gold-molybdenum system is responsible for the alteration and mineralization at Sonora Gulch. With a gold-in-soil anomaly measuring nine square kilometres coupled with the fact that we have only tested a handful of the recommended Titan 24 chargeability anomalies, Sonora Gulch continues to be a high-priority exploration target.”

3Ace

Northern Tiger has completed the initial surface exploration program at 3Ace, consisting of prospecting, mapping and sampling. The primary objectives of the 2010 program were to investigate the extent of high-grade gold mineralization associated with the discovery vein, where previous grab samples returned values up to 140 ounces per ton and to explore the rest of the property for additional mineralized structures and systems. High-grade assays have now been returned from four separate gold zones, and additional results are pending.

Hand trenching has traced the discovery vein for approximately 50 metres along strike before it disappears under heavy overburden. The north-trending discovery vein dips minus-50 degrees to the east and is hosted in a shear zone (the Main zone) which crosscuts a contact between interbedded quartz-pebble conglomerate and fine-grained phyllite lithologies. The exposed sections of the vein have averaged approximately one metre in width. Results from a soil sampling grid suggest that the Main zone extends for a minimum of 100 metres, and also suggest the presence of a second mineralized vein to the east (up-slope) of the discovery vein.

A second zone named the Sleeping Giant and located approximately 1.2 kilometres east of the Main zone consists predominantly of a white massive quartz vein with variable amounts of course crystalline arsenopyrite. Sampling of the vein has also identified visible gold in three locations. The mineralized structure trends north, has a minimum width of 25 metres, and has been traced along strike for 300 metres before disappearing under overburden. To date, assays received from 20 rock samples have ranged from trace to 44.2 grams per tonne gold (from a 1.1-metre chip sample).

The Green zone is located two kilometres north of the Main zone and consists of an east-west-trending zone hosting scoroditic and arsenical mineralization extending at least two kilometres in strike along a property-scale structural corridor. Mineralization occurs both within small veins and, more commonly, as strongly altered quartz-pebble conglomerate wall rock, commonly brecciated and associated with strong clay alteration and local silicification. To date, assays have been received from 67 rock samples and returned values from trace to 66.5 g/t gold (from a grab sample). A total of 17 rock samples returned values in excess of 1.0 g/t gold.

The North zone, located roughly 500 metres east-northeast of the Main Zone, consists of metre-scale quartz veins with arsenopyrite, minor galena and visible gold. Assays received to date from 14 rock samples range from trace to 90.8 g/t gold and 5.0 g/t silver (from a 1.5-metre chip sample). Roughly 70 metres to the east, another 1.5-metre chip sample of quartz pebble conglomerate with quartz veining and clotty arsenopyrite returned 1.5 g/t gold. Both samples occur within an area of abundant quartz veining and strong silicification within quartz-pebble conglomerate.

Assays have been received for approximately 58 per cent of a large program of chip, rock, soil and silt sampling. Additional results are pending.

Sonora Gulch

The Sonora Gulch project is 100 per cent owned by Northern Tiger and is located in the central Yukon’s Dawson range. Twelve diamond drill holes totalling 2,875 metres were recently completed on the Sonora Gulch property. Two of the 12 holes were abandoned at shallow depths due to difficult drilling conditions. The program was primarily designed to test for the presence of a porphyry copper-gold-molybdenum system as suggested by past exploration results and two holes were also collared in a gold-in-soil anomaly (the Gold Vein zone).

Drill hole locations were chosen based on a combination of factors including geophysical interpretation, alteration and geology, and focused on the central portion of a previously identified copper-molybdenum soil anomaly covering over two square kilometres. This area exhibits extensive surface expressions of sericite-pyrite (phyllic) alteration flanked to the north and south by chlorite-epidote-pyrite (propylitic) alteration. The south flank of the phyllic zone extends along Little Kline’s Gulch which is largely overburden-covered although some exposures contain foliation controlled magnetite/biotite (potassic) alteration within altered metavolcanic rocks. A number of the drill holes targeted anomalies identified by a deep-penetrating geophysical survey done by Quantec Geosciences Ltd. and also tested radiometric and magnetic targets identified from a 2009 airborne geophysical survey. Quantec recommended a total of 29 drill holes (including 14 high priority holes) to test chargeability anomalies identified by the Titan 24 survey. Due to the relatively modest drill program, large number of promising targets and logistical limitations of using a skid-mounted drill, only five of the recommended Titan 24 chargeability targets were drill tested in the 2010 drill program. The balance will be considered for drilling in 2011.

The first three holes (SG10-45, 46, 47) cored strongly silicified quartz feldspar porphyritic monzonite containing disseminated and fracture controlled pyrrhotite with minor chalcopyrite. Later holes encountered carbonate-altered metavolcanic wall rock exhibiting skarn and replacement-style sulphides, locally semi-massive. This includes massive magnetite and semi-massive pyrite plus/minus pyrrhotite plus/minus chalcopyrite plus/minus molybdenite along open fractures and in crosscutting quartz veins. Assays from the first five holes (including the two abandoned holes) have revealed sections of geochemically anomalous copper, gold and/or molybdenum values, although no economically significant zones of mineralization are indicated to date. Assay results are pending for the remaining holes.

Minto-style targets

A two-hole (404 m) diamond drilling program has recently been completed on the Dad property. The drilling tested a gradient array induced polarization (GAIP) anomaly coincident with a copper-in-soil geochemical anomaly suggestive of Minto-style disseminated sulphide mineralization. Assay results are pending.

Samples from Sonora Gulch were analyzed by ALS Chemex of North Vancouver, B.C., Canada, using 50-gram fire assay and 35-element ICP analysis. Samples from 3Ace were analyzed by Inspectorate America Corporation of Richmond, B.C., using 50-gram fire assay and 50-element, four-acid ICP analysis. Samples returning in excess of 30 g/t gold are also sent for metallic screen fire assay testing.
