Towards a critical resource

Saville Resources exceeds historic high grades for niobium-tantalum in Quebec

by Greg Klein

The project’s first drill campaign in nine years poses a big question: Why was this the project’s first drill campaign in nine years?

Saville Resources/Commerce Resources report best-yet niobium hole from Quebec critical minerals project

Even in the face of highly encouraging historic niobium-tantalum results, this program’s first hole exceeded expectations. More near-surface high grades and wide widths followed, culminating in a fourth hole that surpassed them all. Now Saville Resources TSXV:SRE looks forward to more drilling to build an inferred resource on the Niobium Claim Group in northern Quebec’s Labrador Trough.

But why the nine-year hiatus? The answer can be illustrated by Commerce Resources’ (TSXV:CCE) Ashram rare earths deposit, two kilometres away. Moving that project towards pre-feasibility took precedence, even when the company found strong niobium-tantalum intercepts on another part of its Eldor property. To give these other critical minerals their due, Commerce and Saville signed an agreement last year allowing the latter company to earn 75% of the 1,223-hectare niobium claims.

Additional high-grade boulder samples renewed interest in a number of prospective areas but Saville’s initial drill program in spring 2019 targeted Mallard, the most advanced zone with 17 historic holes totalling 4,328 metres. The new program added five holes (one hole was lost) and 1,049 metres.

“We were confident that we could improve on the historic drill results and we did that,” notes Saville president Mike Hodge.

Near-surface highlights from the best hole showed 0.8% Nb2O5 over 31.5 metres, 0.79% over 37 metres, 0.67% over 19.95 metres and 0.5% over 33.5 metres. Eleven individual samples from that hole exceeded 1%, with one sample reaching as high as 1.68% over 1.5 metres. (True widths were unknown.) Tantalum and phosphate also brought strong numbers.

A 50-metre step-out east of another of the campaign’s successful holes, 50 metres southeast of a second and 200 metres southeast of a third, EC19-174A was also proximal to impressive historic results.

In just a few of the recent highlights, however, EC19-173 featured 0.66% Nb2O5 over 14.5 metres. EC19-171 hit 0.7% over 38.28 metres, including 1.1% over 5.41 metres. EC19-172 reached 0.62% over 19 metres.

Among tantalum grades were 274 ppm Ta2O5 over 100.8 metres from EC19-172, and 267 ppm over 26 metres from EC19-171.

The step-outs extend Mallard’s strike 100 metres southeast and also suggest a possible northern extension towards the project’s Miranna and Spoke targets, as yet undrilled.

That’s despite very high-grade boulder samples from Miranna showing 2.75%, 4.24%, 4.3% and an exceptional 5.93% Nb2O5.

“These are still untested targets which we believe could have significantly higher grades than Mallard,” says Hodge. “But my first goal would be an inferred near-surface resource in the Mallard area.”

Contributing to that would be historic data, which includes intervals of 0.82% Nb2O5 over 21.9 metres, 0.9% over 4.8 metres and 1.09% over 5.8 metres.

In all, the Niobium Claim Group underwent 41 historic holes for 8,175 metres, with all field work since 2008 conducted by Dahrouge Geological Consulting. Saville has so far exceeded its first-year spending commitment of $750,000 out of a five-year, $5-million exploration agenda that would earn 75% of the project from Commerce.

But if Miranna’s 5.93% Nb2O5 sample looks outstanding, another boulder collected west of the project’s Northwest area soared up to 16.1%, also showing 7,540 ppm Ta2O5.

“That was the highest, but there were plenty in the 3% to 6% niobium range,” Hodge emphasizes.

With overlapping boulder trains on the property, “there are a few locations they could be coming from,” he adds. “But the likelihood of it coming from the Spoke or Miranna areas would be the highest probability.”

Other areas of interest include the Northwest zone, northwest of Miranna. Location of 11 historic holes totalling 2,257 metres, its results included 0.61% Nb2O5 over 12 metres.

South of Mallard, the Star Trench area has four historic holes for 664 metres, with results including 1.5% Nb2O5 and 1,810 ppm Ta2O5 over 0.52 metres, and 1.69% Nb2O5 and 2,220 ppm Ta2O5 over 0.31 metres.

Niobium and tantalum both rank on the U.S. list of 35 critical minerals. Heightened concern has brought concerted American efforts to develop reliable sources and create supply chains domestically and with allied countries. In early June the U.S. unveiled its Energy Resource Governance Initiative to work with allies as part of the president’s critical minerals strategy announced a few days earlier.

Imports provide America’s total supply of both niobium and tantalum. Niobium, used for alloys and super-alloys in jet engines, rockets and other manufactures, comes to the U.S. mostly from one company in Brazil. According to 2018 figures from the U.S. Geological Survey, Brazil mined 88.2% of global supply, while Canada extracted another 10.3%.

Tantalum finds widespread use in electronics as well as super-alloys for jet engine components. USGS numbers from last year attribute 39.5% of global supply to the Democratic Republic of Congo, 27.8% to Rwanda, 8.3% to Nigeria and 6.7% to China. Apart from security of supply, concerns about conflict minerals result from troubling conditions and murky supply routes in the DRC and Rwanda.

Meanwhile Hodge wants to get back to the field. “We made a great first step in expanding on what we had,” he says. “All of these holes ended in a mineralized zone. The reason we stopped them there was to start a near-surface inferred resource. There’s carbonatite with mineralization in niobium, tantalum and phosphate open in all directions, so the results definitely call for more drilling.”

Visual Capitalist considers the hydrogen city: How hydrogen can help achieve zero emissions

May 14th, 2019

In the modern context, cities create somewhat of a paradox.

While cities can improve the lives of people and entire nations, they also tend to be the main contributors of pollution and CO2 emissions.

How can we encourage this growth, while also making city energy use sustainable?

Resolving the paradox

This infographic comes to us from the Canadian Hydrogen and Fuel Cell Association and it outlines hydrogen technology as a sustainable fuel for keeping urban economic engines running effectively for the future.

The hydrogen city How hydrogen can help achieve zero emissions

 

The urban economic engine

Today, more than half of the world’s population lives in cities and, according to U.N. estimates, that number will grow to 6.7 billion by 2050—or about 68% of the global population.

Simultaneously, it is projected that developing economies such as India, Nigeria, Indonesia, Brazil, China, Malaysia, Kenya, Egypt, Turkey and South Africa will drive global growth.

Development leads to urbanization, which leads to increased economic activity:

The difficulty in this will be achieving a balance between growth and sustainability.

Currently, cities consume over two-thirds of the world’s energy and account for more than 70% of global CO2 emissions to produce 80% of global GDP.

Furthermore, it’s projected by the McKinsey Global Institute that the economic output of the 600 largest cities and urban regions globally could grow $30 trillion by the year 2050, comprising two-thirds of all economic growth.

With this growth will come increased demand for energy and CO2 emissions.

The hydrogen-fueled city

Hydrogen, along with fuel cell technology, may provide a flexible energy solution that could replace the many ways fossil fuels are used today for heat, power and transportation.

When used, hydrogen and fuel cell technology creates water vapour and oxygen, instead of harmful smog in congested urban areas.

According to the Hydrogen Council, by 2050 hydrogen could generate annually:

  • 1,500 TWh of electricity

  • 10% of the heat and power required by households

  • Power for a fleet of 400 million cars

The infrastructure requirements for hydrogen make it easy to distribute at scale. Meanwhile, for heat and power, low concentrations of hydrogen can be blended into natural gas networks with ease.

Hydrogen can play a role in improving the resilience of renewable energy sources such as wind and solar, by being an energy carrier. By taking surplus electricity to generate hydrogen through electrolysis, energy can be stored for later use.

In short, hydrogen has the potential to provide the clean energy needed to keep cities running and growing while working towards zero emissions.

How fares Canada in the Fraser Institute’s global mining survey?

February 25th, 2015

by Greg Klein | February 25, 2015

Saskatchewan’s number two worldwide, Quebec’s back in the top 10 and Manitoba climbed 17 notches. But Alberta, Ontario and British Columbia took a beating in the latest Fraser Institute survey of mining jurisdictions. Released February 24, the study rates 122 jurisdictions (including provinces and states in Canada, the United States, Australia and Argentina) based on 485 returned questionnaires. Drawing on their 2014 experience, mining and exploration companies provided numerical ratings for a number of factors, which the institute tracked on separate indexes.

Most important is the Investment Attractiveness Index, which combines two other indexes—Best Practices Mineral Potential (geology) and Policy Perception (government attitudes). The institute weighs the IAI 60% for geology and 40% for public policy, roughly the same consideration companies reported for their investment decisions.

Here’s the top 10 IAI globally, with 2013 rankings in brackets:

1 Finland (4)
2 Saskatchewan (7)
3 Nevada (2)
4 Manitoba (13)
5 Western Australia (1)
6 Quebec (18)
7 Wyoming (11)
8 Newfoundland and Labrador (3)
9 Yukon (8)
10 Alaska (5)

Here are the Canadian runner-ups:

15 Northwest Territories (25)
21 New Brunswick (23)
22 Alberta (10)
23 Ontario (14)
28 British Columbia (16)
29 Nunavut (27)
42 Nova Scotia (47)

Prince Edward Island wasn’t included.

As for the bottom 10:

113 Sudan
114 Nigeria
115 Bulgaria
116 Guatemala
117 Egypt
118 Solomon Islands
119 Honduras
120 Kenya
121 Hungary
122 Malaysia

The 122 jurisdictions totalled 10 more than in 2013. For inclusion, the institute requires a minimum of 10 responses per jurisdiction.

The anonymous replies also included comments which, for Canadian provinces and territories, note serious but unsurprising concerns.

But for some people, the rankings rankled. B.C.’s 10th-place finish out of 12 Canadian jurisdictions doesn’t jibe with the province’s second-place status for mining investment, according to the Association for Mineral Exploration British Columbia. Citing data from Natural Resources Canada, AME BC credited Ontario as Canada’s favourite for attracting investment. Fraser Institute respondents stuck that province with ninth place in Canada.

“Furthermore, one of the best indicators of success in exploration is seeing discoveries move through to mine development,” said AME BC president/CEO Gavin Dirom. “In recent years, we have seen a number of new major metal mines constructed in our province, including Copper Mountain in 2011, New Afton in 2012 and Mount Milligan in 2013. Also, Red Chris is being readied for commercial operations, and the KSM and Kitsault mine development projects have received environmental assessment certificates.”

The NWT and Nunavut Chamber of Mines noted the Northwest Territories’ considerable improvement and its breakaway territory’s slight slump. The organization vowed to continue working with federal and territorial governments “to improve the investment climate for exploration and mining in the two territories.”
