Trenching was conducted to test the historical gold-in-soil anomaly, and to follow up on a float sample that ran 14.1% copper. Following excavation of the first trench (TR07R-01), other trenches were excavated along the projected strike extension of the shear zone, with trench TR07R-05 being located approximately 315 m (1,033 feet) from the first trench. The trenches were excavated to a maximum depth of 3 m (10 feet) and up to 40 m (131 feet) in length. Trenching in 07R-01 exposed fractured, altered and oxidized biotite granodiorite, with abundant azurite staining, black Cu-rich coating and local malachite and chrysocolla. This material is cross-cut by epithermal dolomite-quartz veining. All samples of the oxidized sheared intrusive rock were mineralized. Composite grab samples collected in Trench 07R-01 were followed up by a systematic program of mapping and chip sampling in TR07R-01, the highlights of which are on the table above.
Approximately 15 meters (49 feet) to the northwest of the shear zone in TR07R-01, a grab sample (G2419) of discrete clayey alteration zones on fractures in massive intrusive rock returned values of 16.90g/t Au, 140.0 g/t Ag, 0.43% Cu, 0.85% Pb and 0.42% Zn.
Two grab samples (G2411 and G2412) from TR07R-03 of azurite-stained biotite-rich intrusive rock were taken roughly 200 meters (660 feet) south of TR07R-01and returned values of 4.5% Cu and 10.4% Cu.
The Ridge Zone is in an area primarily underlain by mid Cretaceous granodiorite (Casino Granodiorite) that intrudes the Paleozoic or older basement metamorphic complex of the Yukon Tanana Terrane. The Ridge Zone is located within a biotite-rich granodiorite, at or near the contact between the Casino granodiorite and the later Bow Creek granite.
Northern Freegold's 2007 reconnaissance program was the first systematic exploration program on the central part of the Mount Freegold property since the late 1980's.
The Stoddart Zone is a discovery of a new mineralized porphyry body located 1 km from the Ridge Zone, in the central portion of the district scale Freegold Mountain Project, Yukon. Two diamond drill holes (509 m, 1,670 feet) tested a historical 1300 by 400 m (4,265 by 1,312 foot) gold and copper soil anomaly coincident with an airborne magnetic survey anomaly.
Results from 2007 Drill Holes
- Both diamond drill holes intersected significant mineralization indicative of a porphyry system located at or near surface.
- Drill hole ST07-01 intersected 159.25 m (522.47 feet) of 0.14% copper including 15.75 m (51.66 feet) of 0.33% copper.
- Drill hole ST07-02 intersected 205.65 m (674.53 feet) of 0.15% copper including 26.40 m (86.61 feet) of 0.27% copper.
- The Stoddart Zone is located 1 km from the Ridge Zone where chip sampling returned 4.70 m (15.74 feet) of 0.11 oz/ton gold, 1.83 oz/ton silver and 0.59% copper.
- In 2008 a total of 10 holes totaling 2560 m (8,397 feet) were drilled in 2008 to expand upon the 2007 discovery of porphyry style mineralization.
