Gold Canyons Winter Drilling at Springpole Gold Project Produces Long Gold Intercepts and First Bonanza Grades From Portage Zoneadmin
Gold Canyon Resources Inc. is pleased to announce the return of assays from the first 5 drill holes of its Winter 2011 Diamond Drill Program at its 100% controlled Springpole Gold Project, located 110 kilometers northeast of the Red Lake Mining Camp, Ontario, Canada. Highlights include hole SP11-033 that intersected the first bonanza grade gold mineralization yet encountered in the Portage Zone, including 3 meters at 53.88 grams per tonne gold (10 feet at 1.573 oz per ton gold) within 302 meters at 1.39 grams per tonne gold (991 feet at 0.041 oz per ton gold). Using an upper cut-off of 34.25 grams per tonne (1 oz per ton) for single assays, these intervals become 3 meters at 23.12 grams per tonne gold (10 feet at 0.675 oz per ton gold) and 302 meters at 1.08 grams per tonne gold (991 feet at 0.032 oz per ton gold).
“Holes SP11-033 and -34 come from an area near the middle of the Portage Zone where there is mostly historic drilling from nearly 20 years ago,” comments Dr. Quinton Hennigh, Technical Advisor to Gold Canyon. “Though we are pleased that both holes produced long intervals of typical Portage style mineralization, the high grade in SP11-033 is something not previously seen in modern or historic drilling. We are hopeful further drilling in this area might produce more of this style of mineralization.”
“We are also very pleased to see near surface mineralization in holes SP11-030 and -031 drilled in the gap between the Main and Portage zones,” continues Hennigh. “We can now confidently say that gold mineralization is continuous for a distance of 1.35 kilometers from the Main Zone in the northwest to the present terminus of the Portage Zone in the southeast.”
– Hole SP11-033 drilled to a depth of 250.5 meters, was designed to test shallow and intermediate depths of the Portage Zone. It drilled above hole SP10-005 drilled last winter 2010, and above SP10-029 drilled in the summer of 2010, which tested the zone at depths of nearly 250 meters. SP11-033 was drilled at an azimuth of 220 degrees true north and inclination of -45 degrees. It was drilled from the same location as hole SP11-032 (inclination of -45 degrees), which was lost in bad ground at a depth of 70 meters. SP11-033 intersected the first bonanza grade gold mineralization yet encountered in the Portage Zone, including 3 meters at 53.88 grams per tonne gold (10 feet at 1.573 oz per ton gold) within 302 meters at 1.39 grams per tonne gold (991 feet at 0.041 oz per ton gold). The high grade interval includes a one meter interval at 126.51 grams per tonne gold (3 feet at 3.694 oz per ton). Using an upper cut-off of 34.25 grams per tonne (1 oz per ton) applied to this sample, these intervals become 3 meters at 23.12 grams per tonne gold (10 feet at 0.675 oz per ton gold) and 302 meters at 1.08 grams per tonne gold (991 feet at 0.032 oz per ton gold). Encouragingly, SP11-033 encountered gold mineralization beginning at 13 meters at the beginning of bedrock immediately below the lake bed. – Hole SP11-034 was collared approximately 100 meters southeast of SP11- 033; drilled at an azimuth of 220 degrees true north, an inclination of -45 degrees and drilled to a total depth of 379.5 meters. This hole tested intermediate levels of the Portage Zone in an area where only 20 year old historic drill holes are present. Two mineralized intervals were encountered; 73.5 meters at 1.18 grams per tonne gold (241 feet at 0.034 oz per ton gold) beginning at 37 meters down hole, and 169 meters at 1.08 grams per tonne gold (554 feet at 0.032 oz per ton gold) beginning at 162 meters down hole including 51 meters at 2.20 grams per tonne gold (167 feet at 0.064 oz per ton gold). It is clear that the Portage Zone bifurcates in this location, something seen locally in previous drill holes elsewhere along the zone. – Holes SP11-030 and -031 both tested an 80 meter wide near surface gap between the Portage Zone and the Main Zone further northwest. SP11-030 was drilled at an azimuth of 220 degrees true north and inclination of -45 degrees, and drilled to a downhole depth of 241 meters; SP11-was collared approximately 50 meters southeast from SP11-030 and was drilled with the same orientation to a downhole depth of 238 meters. Hole SP11- 030 encountered 59 meters at 2.51 grams per tonne gold (194 feet at 0.073 oz per ton gold) beginning at 14 meters down hole, and hole SP11- 031 encountered 85.6 meters at 1.09 grams per tonne gold (281 feet at 0.032 oz per ton gold) beginning at 5.4 meters down hole. These results indicate the Portage and Main zones are connected and form one single body of gold mineralization. – Core recovery remains a challenge in the Portage Zone which is comprised of soft, broken, highly altered rock. Numerous intervals of no core recovery were encountered in holes SP11-033 and -034. Hole SP11-032 was lost in bad ground when the core barrel broke off. Note that in the table below, many intervals of no core recovery in holes SP11-033, and -034, fall within mineralized intervals and in some cases higher grade intervals. These zones are given a grade of zero when calculating weighted averages reported below, and therefore have a negative effect on the overall results. The Company continues to work diligently with the drill contractor to mitigate loss of core. This includes use of specialized mud mixes, slower drilling and the use of specialized soft core recovery tools. As a consequence, the total meters drilled thus far stands at approximately 3,000 meters. It is hoped that the pace will pick up over the next few weeks of the drill program as new measures are being taken to improve the speed of drilling. The Company now expects to complete around 6,000 meters, less than the 9,000 meters originally planned. Plans are underway to bring in two barges across the winter road before breakup so that drilling may continue in late spring to early summer. Critical holes that are not completed this winter will be drilled in that period so that the Company can meet its goal of revising a resource estimate in 2011, and continuing the exploration effort at
The Winter 2011 Diamond Drill Program is part of an ongoing program of drilling and remodeling of the Springpole Gold deposit to move it towards prefeasibility. Drilling is planned to continue through April 2011, at which time work will begin on revising the resource estimate for the deposit.
Springpole is an alkaline intrusion hosting a gold system that represents a potentially new style of Canadian Archean Shield gold deposit. Springpole shares many similarities with deposits such as the Cripple Creek Gold deposit in Colorado. The Portage Zone is hosted by a trachytic porphyry intrusion displaying polyphase autolithic breccias that contain gold mineralization of remarkably uniform grade. Other zones, including East Extension, Camp and Main, consist of high grade veins and pods hosted in diatreme breccias composed of intrusive and country rocks. These diatreme breccias surround the northwest and northern margins of the Portage Zone. The known mineralized zones underlie a total known area of about 4 square kilometers representing only about 15 percent of the greater alkaline intrusive complex which yet remains to be explored.
Core was logged, then split using diamond saws, with one half sent for analyses and the other half stored for future reference. Quality control programs include the use of field and laboratory duplicates, standards, blanks, and internal and external check assaying. Certified sample standards were submitted with the normal sample stream. Gold and silver assays were completed by SGS Canada Inc. in Red Lake and Toronto, Ontario using a 30 gram charge, fire assay, with an ICP finish. For over limit assay results, initial assays in excess of 10.0 grams per tonne Au, a gravimetric finish is utilized.
