Tad samples up to 0.14 m of 52.48 g/t Au at Hazelton
Posted by Admin in Corporate Updates, Field Work, News Releases on November 6th, 2009
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.
Eastfield Resources Announces Crew Mobilized to Zymo Gold Copper Project, BC
Posted by Admin in Field Work, News Releases on July 14th, 2009
Eastfield Resources and Canadian Gold Hunter are pleased to announce that a drill has been mobilized to the Zymo copper-gold property 45 kilometres west of Smithers, BC.
The Zymo property is underlain by an alteration/sulphide system of over 15 square kilometres and hosts several mineralized targets. A drilling program of four to six holes is planned and will further test the Hobbes Zone at depth and along strike as well as targets in the FM Zone.
This year’s drill program will follow up on a successful 1,554 metre Drill program in 2008 which intersected significant new intervals of copper/gold mineralization in the Hobbes Zone. Intersections from the 2008 program included 72.0 metres of 0.72% copper and 0.54 g/t gold in hole ZY08-09 and 158.9 metres of 0.31% copper and 0.21g/t gold in hole ZY08-10. Other work in 2008 included an IP/mag geophysical survey and geochemical sampling. An open-ended IP chargeability anomaly measuring six kilometres long by two-three kilometres wide was outlined in 2008 within which both the Hobbes and FM mineralized zones occur. Geochemical sampling and prospecting have outlined at least two new copper-gold target areas.
CGH has the option to earn a 60% interest in the property by completing exploration expenditures of $4 million over five years. CGH may earn an additional 10% interest by completing a feasibility study and an additional 5% by arranging mine financing for Eastfield.

High Grade Copper-Zinc Showing Discovered by Cariboo Rose at Carruthers Pass
Posted by Admin in Field Work, News Releases on July 9th, 2009
Cariboo Rose Resources has been informed that Hawthorne Gold Corp. has terminated its option of the Carruthers Pass property in north-central BC. Hawthorne has forwarded a report outlining the results of their 2008 exploration program. The report details sampling carried out on cliffs above a high-grade boulder protruding from a talus apron. Two significant new bedrock massive sulphide occurrences were located and sampled. Other mineralized zones were also located but massive sulphides were not observed. Previous sampling of the large massive sulphide boulder returned significant values in copper, zinc, silver and gold. Grab samples by Phelps Dodge in 2001 from this exposure returned the following:

The prospecting/sampling program identified at least two mineralized or sulphide-bearing altered horizons which vary between two to four metres thick and can be traced across the outcrop exposures for at least 100 metres. Within these horizons, pods of massive sulphides occur and which are represented by the samples above. It is strongly suspected that these are the source of the boulder occurrence.
An airborne geophysical survey over the property was completed in 2004. A total of 295 line kilometres were flown utilizing a DIGHEM multi-coil, multi-frequency electromagnetic system supplemented with a high sensitivity magnetometer. The geophysical contractor, Fugro Airborne Surveys of Toronto, reports that “the surveyed property contains several anomalous features, many of which are considered to be of moderate to high priority as exploration targets”. The Fugro report itemizes fourteen target areas that contain discrete electromagnetic anomalies attributable to bedrock sources. These targets have had little follow-up exploration.
The Carruthers Pass property consists of 130 mineral claim units covering 3,250 hectares located approximately 70 kilometres south of the Kemess gold-copper mine and 200 kilometres north of Smithers. Under the terms of a 2003 agreement with Phelps Dodge, Cariboo Rose may earn a 100% interest in the Carruthers Pass Property by completing $750,000 ($187,000 remaining) in exploration and issuing shares valued at $120,000 (cash or shares, $40,000 remaining) before the sixth anniversary of the agreement (May 31, 2012). Phelps Dodge retains a back-in privilege to earn a 60% interest by incurring exploration expenditures that are the greater of 200% of prior expenditures or $1,500,000 (with the back-in election to be made before the expiry of the 90 day period following the earlier of May 31, 2011 or the completion of 2,500 metres of drilling [1,100 remaining]). Phelps Dodge may earn an additional 10% interest by completing a feasibility study within three years of earning its back-in interest. Should Phelps Dodge elect not to exercise its back-in privilege it will be entitled to a 2 1/2% net smelter return royalty that may be reduced to 1% by payment of $1,500,000.

Gold Fields Plans a $3.9 Million Toodoggone Exploration Program
Posted by Admin in Field Work, News Releases on April 15th, 2009
Gold Fields has tabled an exploration program for Cascadero’s Toodoggone Project that is budgeted for up to C$3.9 million in 2009.
Cascadero holds a 100% interest in 75 mineral tenures aggregating 30,409 hectares in the Toodoggone region of north central British Columbia. The property is located about 20 km north of Northgate Minerals’ Kemess South Au-Cu mine. As of November 30th 2008, Cascadero Copper and previously Stealth Minerals, spent $9.5 million on exploration consisting of mapping, geochemistry, ground and airborne geophysics and drilling. This work identified a broad corridor of geology prospective for bulk mineable copper-gold porphyry deposits, including the PINE copper-gold deposit.
On March 4th 2009, Cascadero Copper Corporation signed an Option and Joint Venture Exploration Agreement with Gold Fields Toodoggone Exploration Corporation (”Gold Fields”), a wholly owned subsidiary of Gold Fields Netherlands Services BV and a member of the Gold Fields Limited group of companies.
The Agreement grants Gold Fields an option to acquire a 51% interest in Cascadero’s Toodoggone property to be satisfied by incurring expenditures of at least C$5 million over a three year period. If Gold Fields acquires the 51% interest, it has the option to acquire an additional 24% interest in the property which is to be satisfied by spending an additional $15 million or funding the completion of a feasibility study. When Gold Fields provides notice to acquire a 75% interest, Cascadero and Gold Fields will form a 25/75 joint venture for the continued exploration and possible development of the property.
In late March 2009, the Toodoggone Project Management committee met in Vancouver. The work program and budget were presented and reviewed. The first year program consists of airborne geophysics, line cutting, ground geophysics, soil and stream sediment geochemistry and core drilling.
The airborne magnetic survey will be flown at 100 to 50 metre spacing and will cover the southern and eastern 2/3rds (~20,000 hectares) of the claim block.
Grid-based line cutting and Induced Polarization geophysics are focused on a north east trending 3,000 metre wide by 16,000 metre long corridor on the southern flank of the Finlay River valley.
A program of soil and rock geochemistry is also planned in the area of line cutting.
Subsequent to data compilation and interpretation, a core drilling program of up to 3,750 metres is planned that is initially focused within the area of the ground based geophysical program.
The airborne magnetic survey is underway.
Gold Fields expects to mobilize to Cascadero’s Finlay Camp in mid-May.
Cascadero Copper has closed its private placement with Gold Fields Toodoggone Exploration Corporation for 500,000 units at C$0.10 per unit. A unit consists of one common share and one warrant each of which plus C$0.12 can purchase one more common share for a period of one year. Gold Fields Toodoggone Exploration Corporation is a wholly owned subsidiary of Gold Fields Netherlands Services BV and a member of the Gold Fields Limited group of companies.
