Changing our mines
Posted on January 28, 2020 | Natural Resources Magazine
Scientists are growing crops from rock dust from an N.L. gold mine
There may not be gold in them thar hills anymore, but there may be an opportunity for agriculture. That’s if a research project—looking at whether vegetables could be grown in the rock dust left over from the Anaconda gold mine on the Baie Verte peninsula—keeps yielding promising crops.
On average, the mine pulls between 1.5 and two grams of gold from every ton of rock. “A little more than the weight of a paperclip,” says Allan Cramm, Anaconda’s vice-president of innovation and development. “Everything outside of that is waste.” That waste comes in the form of pulverized dust and it just sits there on the mine site, he says. Right now, there’s 2.5 million tonnes of rock dust at the site—and growing. Cramm wants to do something with it.
When he found a soil additive online called Rock Dust, he thought he might have something. A few preliminary tests at Anaconda showed their rock dust might have similar properties to the product he found, so he had more testing done through the College of the North Atlantic. Now he’s working with Raymond Thomas, an associate professor of boreal ecosystems and agricultural sciences at Memorial University of Newfoundland’s Grenfell Campus, on a rigorous three-year round of testing to see if it’s suitable for market. “This is a breakthrough opportunity for mining in general,” Cramm says.
Thomas has a team of three graduate students from Grenfell working on the project. A fourth will be joining the team soon, he says. They test the dust to be sure it’s free of harmful chemicals like cyanide, which is commonly used to separate gold from rock. Then they try to grow crops with it. The project has now finished its first year and so far the results are inspiring, Thomas says. “We have some results that we find surprising. The prospects are very promising.”
If it works out, the findings could have big implications for the mining industry. “I’m really excited about the opportunity to change mining,” Cramm says. •
Published study: New benefits of moose and caribou
Published: 01/16/2019 on Grenfell News Releases
A study of moose and caribou meat and moose antlers has uncovered previously unknown benefits of these products.
A study out of the Grenfell Campus Functional Foods Laboratory points to the fact that caribou meat and antlers are rich in functional lipids (fats) which are potentially useful to treat a number of conditions.
The results of the study have been published in "Molecules," a leading international peer-reviewed open access journal of chemistry, and will be the cover story for the print edition.
What next? The functional foods research group at Grenfell Campus, memorial University, is aiming to study the bioactivity of the functional lipids discovered in moose and caribou meat or antlers in different food, cell and animal disease models.
Nutritional treasures found in moose meat, antlers
Published: 01/22/2019 on CBC News
Raymond Thomas and his team have found evidence of particular types of functional lipids in moose and caribou meat, and in moose antlers, that have shown promise in the treatment of diabetes, inflammation and cardiovascular diseases.
"I've realized from my time here that moose is very, very popular as part of the Newfoundland landscape for positive and negative reasons, so I decided that I was going to look at the lipid profile … of the antlers," said Thomas, whose team is based in the Functional Foods Laboratory on Memorial University's Grenfell campus.
Bay of Islands fisherman Rick Crane says eel company is staying ahead of the game by diversifying
Published: 01/18/2019 on Thewesternstar
Changing with the times is what Rick Crane believes will bring success in the fishery.
That’s why Crane, a commercial fisherman out of Cox’s Cove, sees initiatives like the one being undertaken by North Atlantic Aquaponics Inc. as the way to go.
He’s not looking for a new market and most of the time just fishes for recreation, even though he has a commercial licence.
There’s also a lot of rules and regulations to work with, and it would be expensive to start up given he’d need equipment to get to the brooks and to keep the eels alive.
Even though it’s not for him, he’s pleased to see others, like North Atlantic Aquaponics, get involved.
“I think it’s amazing, to be diverse. This is 2019. This is not the ’80s now. The fishery is changing and for them to do that, they are staying ahead of the game."

Short and humid
Researchers at Grenfell Campus are working to secure an adequate food supply for future generations. Dr. Raymond Thomas and collaborators are exploring mix cropping production systems as an approach to increase availability of feed in the province for livestock.
The aim is to determine whether intercropping will bring about these benefits given the short and humid growing season in Western Newfoundland.
Functional Foods Sensory Laboratory officially opens at Grenfell Campus
Published: 13/02/2019 on Grenfell News Releases
The Functional Foods Sensory Laboratory examines "functional foods" – natural or processed food products with known health benefits beyond basic nutritional needs, such as the antioxidants in blueberries, eggs enhanced with omega 3 fatty acids or the probiotics associated with yogurt.
Support for the lab, which operates under the umbrella of Grenfell's Boreal Ecosystem Research Facility, came from the Government of Newfoundland and Labrador and the Atlantic Canada Opportunities Agency (ACOA), each of which provided $144,250, industry partner Atlantic Aquaponics, which contributed $20,000, and Grenfell Campus, Memorial University, which provided $26,000, for a total of $334,000. This initiative is part of a larger $1.2 million project with the industrial component located at the Industrial Partners Site in Black Duck Siding, NL and the academic component located on the Grenfell Campus of Memorial University.

For the love of eel: N.L. company developing new product for international market
Published: 01/20/2019 on CBC News
For years North Atlantic Aquaponics has been shipping live eels to markets in Korea and Ontario, but now they're working to take their products to a tasty new level.
The company, which started on the west coast community of Robinsons, is collaborating with the Functional Foods Laboratory at MUN's Grenfell Campus in Corner Brook to test and develop a new recipe for kabayaki eel.
The Functional Foods Laboratory, under the direction of Dr. Raymond Thomas, allows students from a variety to backgrounds to test, analyze and develop food products.
This week the public was asked to take part in a tasting experiment that got them to rate and rank four different kabayaki samples based on things like appearance, flavour and texture.

Researchers working to increase the forage quality of corn
Published: 09/02/2016 on Thewesternstar
Raymond Thomas, associate professor in boreal ecosystems and agriculture sciences, is the lead on project looking at improved soil health, forage yield and forage quality by intercrossing vine soybeans and forage corn. Where corn is an exhaustive crop, soybeans are restorative and can add protein to the soil and forage quality of the corn. It can also increase soil quality by fixing atmospheric nitrogen.
“If we grow successfully here, then the dairy farmers can feed (it) to the animals and then that way they can get more milk,” said Mumtaz Cheema, and agronomist at Grenfell Campus, Memorial University of Newfoundland in Corner Brook.
