Located near the Kemess South Mine in one of the most prospective regions in Canada for epithermal gold-silver and porphyry copper-gold deposits. Several untested mineralized areas exist on the property and require drilling. |
 |
 |
First phase drilling to date suggests high-grade veins (gold-silver) exist at the Saunders showing and that the potential for larger veins may exist elsewhere on the property. |

Geophysics, geochemistry and early first phase drilling at the Som showing suggest the potential for copper-gold porphyry mineralization. |
Previous work in the Toodoggone Belt has stimulated substantial exploration for high-grade gold-silver vein systems. The property’s prospective geological and structural setting, as well as proximity to the open pit mine at Kemess South provides a favourable opportunity to explore for porphyry copper-gold deposits on the property.
At the Kemess South Mine grade averages 0.70 grams per tonne gold and 0.23% copper and containing 2.06 million oz gold and 459 million lbs copper (Northern Miner Handbook). Kemess South production in 2007 was 245,631 ounces of gold and 68.1 million pounds of copper. The presence of several known porphyry deposits such as the Kemess North and the Nugget deposit within the southern part of the 110 km long by 50 km wide Toodoggone belt suggests the potential occurrence of similar deposits along the geological favorable belt.
In 2008, Golden Dawn renewed an option agreement to earn-in 100% on the property with a 2% NSR with Stealth Minerals Ltd. The NSR can be reduced to 1% by making a one time, one million dollar payment to Stealth Minerals Ltd.
Expenditures of $1,398,909 have been incurred on the property by Golden Dawn between 2004 and 2007. Exploration included magnetics and induced polarization geophysical surveys over two of the known areas of mineralization on this property in addition to several geochemical and rock sampling surveys.
During the 2007 drilling program the principal target was the Saunders "A" vein that was sampled in 2004 with a 3 metre chip sample across sulphide-bearing epithermal quartz veins that yielded an assay of 23.4 g/t Au and 518 g/t Ag. Drill hole S-07-07 tested this mineralized outcropping, intersecting a mylonitic quartz-pyrite vein 42 metres vertically below the mineralized outcropping, that assayed 19.1 g/t Au and 1020 g/t Ag over 0.3 metres. Drill holes S-07-01 and S-07-02 intersected quartz veins ranging from 10 to 15 g/t Ag and 0.1 to 0.2 g/t Au over widths of 0.7 to 1.0 metres, vertically below the mineralized Saunders "A" showing (see GOM press release January 7, 2008)
During the same drilling campaign two holes were collared on the Som showing on a previously identified IP anomaly. The two holes intersected porphyry-style quartz-sulphide veining, K-feldspar, epidote, chlorite and anhydrite alteration. Copper, molybdenum, zinc and lead mineralization were observed throughout the drill core, along with potassic, phyllic and silicified zones and breccia. Assays showed dispersed moderately elevated values in zinc, copper, silver and gold but no coherent intervals of significantly elevated assays. The porphyry copper potential of the Som and adjacent showings needs to be explored further.
Another untested copper-porphyry target exists on the property south of the Som showing called the Copper Breccia showing. Brecciated and mineralized volcanic material was collected from this area. Grab samples returned assays of 1 to 5% copper, with one sample showing 127 g/t silver. A geochemical soil and rock sampling survey over the showing returned anomalous values in base metals. The Copper Breccia geochemical zone extends northward from the showing for about 600 metres and is open in that direction. The objective of subsequent programs would be to further refine the target with geochemistry, geological mapping and sampling. |
