The True Grit property consists of 1,030 mineral claims covering approximately 257 km² (25,700 Ha). The property is accessible by traveling north from the town of Bay d’Espoir on the Bay d’Espoir Highway for 12 km where the highway transects the property. A 3-phase powerline runs 350 meters to the south of the property.
- The True Grit Gold property hosts diamond drilling intercepts of up to 117 m of 0.60 g/t Au, incl 26 m of 0.83 g/t Au from surface (Moydow Mines, 2002), channel samples of 15.6 g/t Au over 1.0 m (Teck, 1990) and grab samples of 30.2 g/t Au (Teck, 1990). The property hosts a coincident Au-Sb-As soil anomaly to the northeast which measures over 2.6 Km by 0.80 Km that is untested.
- The True Grit project encompasses the southernmost portion of the Gander River Ultramafic Belt (GRUB) line offset, which is the easternmost bounding structure of the Exploits Subzone (a geological subzone formed as a result of the closing of the Iapetus Ocean).
- The GRUB regional thrust fault offset structure is a conduit, and a focus of deep mantle fluids which is believed to be spatially associated with significant gold mineralization in the region.
- New structural model focusing on epizonal orogenic gold within the secondary and tertiary structures stemming along the GRUB line provides a pathway to discovery for new gold deposits and reinterpretations of historically conducted work.
Exploration at the True Grit Property was conducted in February and early March. Exploration consisted of the completion of the VTEM airborne geophysical survey, conducted by Geotech Ltd., which began in Q1. 2,830 total line kilometres were flown to complete the survey with results being processed by Geotech and expected to be received in Q3. Exploits’ in house team along with the company’s partner GoldSpot Discoveries Corp., have began interpreting preliminary data to develop follow up field work on the project. A drill program has been permitted for True Grit but a starting date has not been finalized for this program.
Geology & Structure
The project lays within the Exploits Sub Zone which is underlain by siliciclastic rocks of the St. Joseph’s Cove Group. The St. Joseph’s Cove Formation is comprised of siltstone, pelite, sandstone and conglomerate with minor quartz sericite schists thought to represent altered felsic tuffs. Historical till surveys resulted in numerous high gold grain counts (Pickett, 1990) which led to the discovery by Teck Resources of the two True Grit mineralized zones.
The True Grit #1 showing is a 2 m wide zone of quartz-chlorite veining in rusty sericitic and chloritic siltstone with up to 5% disseminated arsenopyrite and minor pyrite. The mineralization appears to exploit brittle fractures in the centre of a small antiformal fold within siltstone. The average grade of channel sampling within the zone is 7.3 g/t Au over 0.69 m over a strike length of approximately 8 m. The highest-grade channel sample was 15.6 g/t Au over 1 m from the northern portion of the zone. Grab samples up to 30.2 g/t Au were reported (Pickett, 1990). The showing also lies within a 2.6 km long by 0.8 km wide coincident Au-As-Sb- in-soil anomaly.
The True Grit #2 showing occurs 1.2 km to the south of the True Grit #1 showing. Trenching by Teck Resources in 1990 exposed a 50 m wide by 175 m long zone of gold mineralization grading up to 0.48 g/t Au over 47 m in altered pelites/metaturbidites, with 1-3% disseminated pyrite-pyrrhotite-arsenopyrite and, locally, numerous narrow quartz veinlets. Assay results include 9.8 g/t Au over 1 m, 18 g/t Au over 0.5 m and 6.5 g/t Au over 0.5 m. A grab sample of the arsenopyrite bearing quartz vein assayed 9.6 g/t Au. In 2002, Cornerstone joint ventured the property to Moydow Mines International who carried out several phases of drilling in 2003/2004. The best intersection was obtained in hole TG4, which returned 0.60 g/t Au over 117 m including a 26 m wide section grading 0.83 g/t Au. Intersections ranging from 16 to 46 m wide with grades of 0.45 to 0.75 g/t Au were encountered in holes TG3, 11, 12, 22 and 23. An area of approximately 700 m by 200 m, was drill tested to depths of between 120 and 35 m vertically. Portions of the drilled area have steep isoclinal folding accompanied by arsenopyrite mineralization. True Grit #2 also occurs within the same 2.6 km by 0.8 km gold-arsenic-antimony soil geochemical anomaly which hosts True Grit #1. Results of the drilling were interpreted to show that there are broad swathes of 0.5 g/t Au material in essentially stratabound packets with a predominantly east or southerly dip. Recommendations by Cornerstone for future work in the area included geochemical and ground/airborne geophysical programs to better define drill targets. The mineralization in the True Grit area is known to be associated with coincident gold-arsenic-antimony in soil anomalies and geophysics may help identify any structural features that may host or control mineralization. Follow- up work also needs to be done in order to source the highly anomalous concentrations of gold.
