Trillium Gold Mines plans to start drilling on its 100 percent-owned Rivard property, located in the south-west of the Newman Todd project, in the last week of January to augment its major drill program already underway.

The new phase of 2021 drilling is expected to provide further understanding of the structural intersections and the high-grade veining in both along strike and depth at Rivard, where previous shallow trenching revealed "spectacular visible gold".

The initial 5,000-meters drill phase on the Rivard property will target the lateral and depth continuity of the veining as well as the high-grade gold mineralization seen in the trenches, and the southwestern extents of the NT Zone, in areas of little historical drilling. The receipt of the drill permit for the Rivard property was announced on December 23.


"This initial phase of drilling marks an important step towards expanding our understanding of the impact these structural intersections have on the Newman Todd Zone. It also increases our active exploration into known areas of significant high-grade gold mineralization. With limited work and non-traditional exploration methods carried out for over 20 years, it presents an uncommonly exciting situation given the prospectivity of the Red Lake gold camp," said Bill Paterson, head of Exploration at Trillium Gold.

He added that preliminary ground inspection on the Rivard property late in summer 2020 confirmed multiple continuous gold-bearing quartz veins. The veins, exposed on surface and in historical drilling, typically strike at an azimuth of 140 degrees and dip steeply to the southwest. 

Historical drill results from the 2007-08 drilling by E Energy Ventures include 12.38 gpt Au over 2.0 m, 34.07 gpt Au over 1.5 m, 13.65 gpt Au over 1.0 m, and 28.62 gpt Au over 2.9 m.

"At Rivard, gold typically occurs in the veins as coarse, free gold (VG), whereas on the NT property, gold commonly occurs in carbonate- and sulphide-rich breccia horizons as well as in later quartz veins containing VG. Photo 2 shows excellent examples of quartz veining from the Rivard property in a fuchsite-rich host rock, with spectacular VG," the statement continues.

Exploration has been carried out on the Rivard property since the 1930s. In the 1940s, Heath Gold Mines Ltd. collected a 64-ton bulk sample from several pits along a 200 metre length of the main gold-bearing trend. The bulk sample yielded 8.32 ounces of gold (approximately 260 grams of gold) and had an average grade of 0.13 ounces of gold per ton (approximately 4.46 grams per tonne).

In the late 1990s, Rubicon Minerals Corporation optioned the property which then became part of their Red Lake Joint Venture (RLJV) with AngloGold. In 2003 the RLJV was dissolved after AngloGold had earned an overall 60 percent interest. 

Relinquishing all of their interests except for the Rivard and Newman Todd properties, in which it retained a 100 percent interest, demonstrated that AngloGold placed a very substantial value on both the Rivard and Newman Todd properties, now owned 100 percent by Trillium Gold Mines. After Anglo's merger with Ashanti Gold Mines, it suspended all its exploration activities in Canada and terminated the option on the Rivard property.

The 2.2kms-long Newman Todd Zone has a 200-metre-wide structural target, located in the Red Lake Gold Camp. Earlier drilling had mostly focused on testing the zone by targeting the footwall with drilling toward the southeast.

Newman Todd is a highly prospective target with 41 percent of the 165 historic drill holes having intervals of greater than 20 g/t gold over various lengths. Nearly all drillings have been conducted to depths of less than 400 meters.

Vale invests $150mn to extend life of Manitoba operations

Vale’s $150mn investment in operations at Thompson, Manitoba will extend mine life by 10 years

Vale has announced a $150mn CAD investment to extend current mining activities in Thompson, Manitoba by 10 years while aggressive exploration drilling of known orebodies holds the promise of mining well past 2040.

Global energy transition is boosting the market for nickel

The Thompson Mine Expansion is a two-phase project. The announcement represents Phase 1 and includes critical infrastructure such as new ventilation raises and fans, increased backfill capacity and additional power distribution. The changes are forecast to improve current production by 30%.

“This is the largest single investment we have made in our Thompson operations in the past two decades,” said Mark Travers, Executive Vice-President for Base Metals with Vale. “It is significant news for our employees, for the Thompson community and for the Province of Manitoba.

“The global movement to electric vehicles, renewable energies and carbon reduction has shone a welcome spotlight on nickel – positioning the metal we mine as a key contributor to a greener future and boosting world demand. We are proud that Thompson can be part of that future and part of the low carbon solution.”

Vale continues drilling program at Manitoba

Coupled with today’s announcement, Vale is continuing an extensive drilling program to further define known orebodies and search for new mineralization.

“This $150mn investment is just one part of our ambitious Thompson turnaround story. It is an indicator of our confidence in a long future for the Thompson operations,” added Dino Otranto, Chief Operating Officer for Vale’s North Atlantic Base Metals operations.

“Active collaboration between our design team, technical services, USW Local 6166, and our entire Thompson workforce has delivered a safe, efficient and fit-for-purpose plan that will enable us to extract the Thompson nickel resources for many years to come.”

The Thompson orebody was first discovered in 1956 by Vale (then known as Inco) following the adoption of new exploration technology and the largest exploration program to-date in the company’s history.  Mining of the Thompson orebody began in 1961.

“We see the lighting of a path forward to a sustainable and prosperous future for Vale Base Metals in Manitoba,” said Gary Annett, General Manager of Vale’s Manitoba Operations.
