North-western Ontario, 20 km southeast of Red Lake and approximately 1000 km north of Toronto. The Red Lake Extension project (“RLX”) covers the southeastern extension of the Red Lake greenstone belt - host to the Red Lake Mining District which has produced in excess of 20 million ounces of gold. The property is accessible by truck from Red Lake and is crossed by a number of 4-wheel drive and all terrain vehicle tracks and trails.
Highlights & Potential for Discovery:
In February 2012, Osisko Mining Corporation entered into a $5.0 million option agreement to earn 51% interest in Tri Origin`s RLX Gold Project. Tri Origin will be the operator on the RLX property for the first year and Osisko will have the option to become operator each year thereafter.
The RLX property is underlain by extensions of rock units which host the neighbouring Red Lake Gold Mine operated by Goldcorp Inc. It comprises one of the largest contiguous land holdings in the Red Lake District. Geological, geophysical and geochemical work as well as over 30 diamond drill holes completed by Tri Origin have identified mineral occurrences and areas of altered rock containing anomalous gold. A large number of additional targets remain untested. Confirmation of the prospective, geological setting and encouragement from preliminary work warrants the continued systematic evaluation of new targets.
Description of Asset:
The project comprises 100% ownership to mineral rights of 54 adjoining mining claims consisting of 735 claim units totalling an area of 120 square kilometres (11,760 hectares).
Reason for Selection:
Red Lake is one of the richest gold districts in Canada and host to several major, operating and past-producing gold mines. The RLX property covers ten kilometres along the extension of the Cochenour-Gullrock Lake Deformation Zone (the "Mine Trend") and includes Balmer-type volcanic assemblages which host the majority of the gold production in the Red Lake camp. Earlier explorers did not recognize the extension of the Mine Trend and Balmer volcanic rocks and consequently the property was essentially unexplored for gold by previous workers.
Planned Exploration:
Following the 2011 field season an area of interest has been outlined for which follow-up ground geophysical surveys will be completed. Historical ground geophysical surveys will also be re-evaluated for potential diamond drill targets. RLX will be aggressively explored during 2012. Follow-up drilling is also planned during 2012.
Technical information
Project and Regional Synopsis:
The Red Lake Extension project lies at the convergence of the Red Lake and Birch-Uchi greenstone belts, within the Uchi Subprovince of the Archean aged Superior province. These greenstone belts form a continuous 200 kilometre long arcuate belt of volcanic and sedimentary rocks surrounding the Trout Lake batholith. The Red Lake belt situated to the west of the property is well known for its gold production and the Birch-Uchi belt to the east contains numerous important base metal deposits including the past-producing South Bay copper/zinc/silver mine.
The Red Lake/Birch-Uchi greenstone belts consist of three major volcanic assemblages: the Balmer, Woman and Confederation. The Balmer Assemblage hosts all the major gold deposits in the Red Lake area including Goldcorp Inc’s Red Lake Gold Mine. The Red Lake Gold Mine - the largest producer in the 20 million ounce district - continues to be one of the highest-grade gold mines and lowest cost producers in the world and it is currently the largest gold mine in Canada.
Data from regional magnetic surveys indicate a continuity and similarity between the signature of the greenstone units in the Red Lake Mining District and the areas mapped on the RLX property. Airborne electromagnetic anomalies in the Red Lake District abundant in sedimentary rocks hanging wall to the Red Lake Mine can be traced from the Red Lake Mine to the RLX property where they are also abundant in sedimentary rocks believed to be stratigraphically hanging wall to a re-occurrence of the prospective Balmer volcanic rocks.
Recent government publications indicate that the unconformity related to the gold-bearing Balmer volcanic rocks and adjacent Bruce Channel sedimentary rocks trend from the Red Lake Gold Mine in a southeasterly direction to the edge of the RLX property, where the government studies were terminated. Tri Origin’s own mapping of limited rock outcrop and drilling has recognized these favourable rock types and stratigraphic relationships. Thus Tri Origin believes there is significant potential for the occurrence of gold mineralization on the property.
Results to Date:
Although rock exposure is limited, Tri Origin has built up a significant geological database. Geotechnical data also includes results from a 1452 line kilometre “VTEM” airborne magnetic and electromagnetic survey, more than 115 kilometres of ground Induced Polarization geophysical surveying and over 6,000 humus and mineral soil geochemical analyses. A total of 37 diamond drill holes investigating targets at different parts of the property had been completed by 2011. Tri Origin’s 2011 program consisted of 5 holes totalling 837 metres. The holes tested airborne VTEM and soil geochemical anomalies located within a 4.0 kilometres by 2.0 kilometres area at the north western part of the property. All holes were successful in reaching their targets. Four of the drill holes intercepted volcanic rocks which are believed to be of the Balmer volcanic assemblage that contained significant alteration and sulphide mineralization. A zone of strong silica and biotite alteration in hole 5 returned a best assay of 2.46 grams of gold per tonne across a one metre sample interval. Two other holes intersected sulphide -rich intervals of up to 10 metres in thickness.
Soil sampling and geological mapping completed this past field season have outlined an area in the vicinity of the recent drill holes where ground geophysical surveys followed by drilling is warranted.
