Niobium-tantalum in Quebec

Successful sampling readies Saville Resources to drill for critical metals

by Greg Klein

“Building momentum” is the way Saville Resources TSXV:SRE president Mike Hodge puts it. Steady progress, shown most recently through another encouraging sampling program, puts the company’s early-stage niobium-tantalum project in Quebec on track for drilling this winter. Assays so far have the company hopeful about proving up a maiden resource in this mining-friendly jurisdiction next door to a country increasingly concerned about sourcing critical metals.

Conducted by Dahrouge Geological Consulting, the fall
program brought the Niobium claim group to drill-ready status.

The autumn field program met all of its objectives, Hodge enthuses. Twenty-two boulder samples surpassed 0.7% Nb2O5, with 14 of them exceeding 0.8% and one peaking at 1.5%. Tantalum made its presence known too. Those same 14 niobium samples also graded between 160 ppm and 1,080 ppm Ta2O5.

The project gained yet another target, where boulders reached 0.88% and 1.28% Nb2O5. A ground magnetics survey highlighted the prospectivity of the Moira area, already the location of exceptionally high-grade samples. In all, the results show a drill-ready project that should see action this winter.

Saville holds a 75% earn-in from Commerce Resources TSXV:CCE on the Niobium claim group, a 1,223-hectare package on the latter company’s Eldor property in Quebec. Just a few kilometres from the Niobium project and with obvious synergistic potential for Saville, Commerce has its Ashram rare earths deposit moving towards pre-feasibility. All this takes place in a province that demonstrates its support for mining through a number of initiatives, including direct investment and the Plan Nord infrastructure program. The northeastern Quebec region has two treaties in place that clearly define procedures for native consultation. Saville’s three-quarters stake in the Niobium claim group calls for $5 million in work over five years.

A 43-101 technical report filed in September followed field programs by previous companies including 41 holes totalling 8,175 metres drilled by Commerce. In addition to niobium-tantalum, the report noted phosphate and fluorspar as potential secondary commodities.

Some of the standout results from previous sampling came from the property’s as-yet undrilled Miranna area, where boulder samples graded as high as 2.75%, 4.24%, 4.3% and an exceptional 5.93% Nb2O5.

Other locations have been drilled, but not since 2010. Some 17 holes and 4,328 metres on the Southeast area brought near-surface highlights that include:

  • 0.82% Nb2O5 over 21.89 metres, starting at 58.93 metres in downhole depth

  • 0.72% over 21.35 metres, starting at 4.22 metres
  • (including 0.9% over 4.78 metres)

  • 0.72% over 17.35 metres, starting at 70 metres

  • 0.71% over 15.33 metres, starting at 55.1 metres

True widths were unavailable. Southeast results also showed tantalum and phosphate, as well as suggesting a possible fluorspar zone.

A wide, near-surface interval from the Northwest area showed:

  • 0.46% Nb2O5 over 46.88 metres, starting at 30.65 metres
  • (including 0.61% over 11.96 metres)

Surface outcrops and near-surface core
produce encouraging grades for Saville Resources.

As in the Southeast, the Northwest area showed encouraging signs of tantalum and phosphate. But tantalum came through most strongly in the property’s Star Trench area, with results as high as 1,810 ppm Ta2O5 (with 1.5% Nb2O5) over 0.52 metres, as well as 2,220 ppm Ta2O5 (with 1.69% Nb2O5, and phosphate grading 20.5% P2O5) over 0.31 metres.

Another area gains greater prominence too, thanks to this autumn’s ground magnetics survey. A strong anomaly at the Moira target, about 250 metres north of Miranna, coincides with several overlapping boulder trains that suggest Moira could be one of several possible sources of mineralization.

And a new, yet-to-be-named area gave up two of the fall program’s best assays. About 400 metres south of the drill area, the new target produced boulder samples hitting 1.28% Nb2O5 and 260 ppm Ta2O5, along with 0.88% Nb2O5 and 1,080 ppm Ta2O5.

Intriguingly, glacial ice suggests the two rocks, found about 100 metres apart, originated in an area farther southeast that’s had very little attention so far.

Saville also holds the 3,370-hectare Covette project in Quebec’s James Bay region, where last summer’s field program found surface samples including 1.2% zinc and 68.7 g/t silver. Three other samples returned nickel values ranging from 0.13% to 0.19%.

Work focused on a highly conductive area identified by a 2016 VTEM survey. Samples gathered in 2017 included grades of 0.18% nickel, 0.09% copper and 87 ppm cobalt. One historic, non-43-101 grab sample brought 4.7% molybdenum, 0.73% bismuth, 0.09% lead and 6 g/t silver, while another historic sample returned 1.2 g/t silver and 0.18% copper.

As for niobium, it’s considered a critical metal by the American government for its use in steels and super-alloys necessary for jet engine components, rocket sub-assemblies, and heat-resisting and combustion equipment, according to the U.S. Geological Survey. Almost 90% of last year’s world production came from Brazil, where new president Jair Bolsonaro has expressed concern about increasing Chinese ownership of resources.

Also a component of military super-alloys, tantalum additionally plays a vital role in personal electronics including phones and computers. The U.S. imports its entire supply of tantalum. About 60% of last year’s world production came from the troubled countries of Rwanda and the Democratic Republic of Congo.

With the advantages of markets, jurisdiction and geology, Hodge looks forward to winter drilling. “We’ve now got about 20 targets that we can go after,” he says. “One priority would be to define the Southeast area because we’ve got such good niobium numbers there. On getting a potential inferred resource, we’d go after Miranna or Moira and the untested targets. We’re looking forward to a busy, productive season.”
