Tad samples up to 0.14 m of 52.48 g/t Au at Hazelton

TAD Capital Corp. has completed the 2009 program on the north zone of the Hazelton prospect. Work consisting of geological, geochemical and geophysical surveys has resulted in several new high-grade gold discoveries and increased the area of known gold mineralization on the property to 1,400 metres by 800 metres.

The program focused on evaluating the extent of mineralization near the margins of a granitic stock. Numerous gold-bearing veins are present in three areas situated along the perimeter of a Cretaceous stock, which measures 600 metres in diameter. Indications are that the stock is part of a larger intrusive body mapped digitally by the Geological Survey of Canada in 2008. The composition of the concealed intrusion is unknown but judging from surface exposures it ranges from granite to granodiorite and includes monzonite phases and rhyolite dikes.

Gold mineralization on the property conforms to a broadly defined intrusion-related class of deposits with gold mineralization hosted within a thermal aureole. The distinctive features of this class of gold deposits are sheeted arrays of parallel, single-stage quartz veins which are found over tens to hundreds of metres and preferentially located in the pluton’s cupola. These types of veins are also described as reduced intrusion-related gold systems represented by the Fort Knox, Pogo, Donlin Creek and Dublin Gulch deposits in Alaska and the Yukon.

Past work had recognized that the sulphide mineralogy of individual veins varies along strike and possibly along the dip direction. Sulphide content ranges from 2 to 45 per cent, and consists mainly of arsenopyrite (up to 30 per cent) and pyrite (up to 30 per cent).

The mineralization observed to date has two mineralogical characteristics that impact the precious-metal grades: mineralization dominated by arsenopyrite-pyrite-banded intergrowths; and mineralization dominated by banded arsenopyrite with minor pyrite-galena-sphalerite-tetrahedrite at the vein margins.

Locally, the veins carry small amounts of copper sulphides that include tetrahedrite. This mineral association is of particular significance and has returned a high-grade gold of up to 52.48 grams per tonne gold in one sample.

Camp area

In the Camp area, there are a minimum of 13 quartz-sulphide veins present over an area measuring 150 by 200 metres. The area is situated between two deeply incised creeks named West Creek and East Creek. Work completed in 2009 resulted in the exposure of six new veins.

The majority of the veins strike northwesterly and have gentle dips to the northeast with true widths ranging from six to 47 centimetres. One of the newly found mineralized zones consists of two 25-centimetre-thick veins separated by a 30-centimetre zone of altered monzonite host rock. The veins were exposed in a 0.8-metre-by-one-metre trench and sampled across a 0.8-metre width. This site returned 1.91 grams per tonne gold and 8.0 grams per tonne silver (sample 723372).

Two veins in close proximity to each other have been exposed by shallow trenches (samples 723351 and 723352). The vein dipping gently to the north (723351) contained 20 per cent sulphides with arsenopyrite being the dominant sulphide. The vein dipping gently to the northeast contained relatively high pyrite and lesser arsenopyrite (723352). The latter vein returned 52.48 grams per tonne gold and greater than 100 grams per tonne silver.

Re-exposure of a 1988 trench has resulted in the documentation of a 127-metre-long quartz-sulphide vein striking 346 degrees. Several locations along this trench were re-excavated using hand tools and then sampled. The vein is dipping to the east-northeast at a 44-degree angle and ranges in width from 15 to 35 centimetres. Four channel samples returned an average weighted content of 3.74 grams per tonne gold and 9.13 grams per tonne silver. One sample from a silica-sulphide cemented fault fracture returned 3.62 grams per tonne gold and 6.4 grams per tonne silver across six centimetres.
