Is Rossland’s mining history about to come to life again?

Though Rossland’s mining industry has been dormant since the early 1970s, there have always been rumblings about undiscovered riches in the area and it’s not uncommon to see prospectors hiking off into the bush each spring.  Now there’s a chance that large scale mining may be returning to the area. The gold rush days are long over, but it may be time for a...magnesium rush?

In 2001, two Calgarians, Frank Marasco Sr. And his son Frank Jr., came to Rossland to investigate an old mining claim called the ‘O.K.’. The Marascos were interested in getting into the gold mining business. Subsequently, the pair acquired the Midnight, IXL, Snowdrop, and Golden Drip claims, hired a team of geologists, and began exploring.

Their search led them west along the Cascade Highway to the 8K mark, where they discovered the same ultramafic rock they had encountered in a group of claims west of Little Sheep Creek. Volcanics were also predominant there.

They drilled near 8K and though they were originally looking for gold, they didn’t find any. Instead, they found magnesium—a lot of magnesium.

Now, after having spent close to twelve million dollars on exploration over the last decade, the Marascos have established the presence of a world class ore body of 9.1 million metric tons of magnesium ore (which is roughly 23.1% magnesium by volume).

The Marascos’ company, West High Yield Resources, a publicly traded company on the Toronto Stock exchange, now intends to establish a mine and processing facility on their claims.

Magnesium is considered a ‘green’ and in-demand commodity. Magnesium board can replace gyprock, OSB, plywood, and cement board; it is fireproof, smoke proof, water proof, mould and mildew proof. 

Marasco says that there are many claims that can be made in favour of magnesium: increased use of magnesium in building reduces the demand for logging, thereby preserving forests. Additionally, magnesium-based cement products extract CO2 from the atmosphere as part of their drying process.  Finally, magnesium alloy is a growing component and becoming a requirement in construction of all new automotive products, which will contribute to a reduction of CO2 emissions.

Asked how such a mine might benefit the local community, Frank Marasco  (the company’s president and CEO) replied, “Well, after all the extensive provincial and federal permitting and ecological protocols have been met, it will mean probably around 300 direct jobs in the community for decades.

“The raw material is here. All we have to do now is mine and process it. There will be little waste product to speak of as we have determined that we can utilize almost all of what we take from the ground. We are hopeful that we can be a benefit to the community of Rossland and help provide a financial base for growth and progress for many years to come.”

Rossland gold and geology

Note to the editor: Although I enjoyed reading about W.H.Y. Resources local developments in your article, “Is Rossland’s mining history about to come to life again,” the opening statement, “Though Rossland’s mining industry has been dormant since the early 1970’s,” is incorrect. Mining underground for gold (using existing historical tunnels) took place on both the Iron Colt and Evening Star claims (Monte Christo – Columbia Kootenay Mountain areas) from 1992 to 1996.

(Briefly), for those interested or concerned...

- Virtually all of developed core Rossland is underlain by barren (without gold) Rossland monzonite (a granite like rock used in the Post Office, Bank of Montreal and Court House foundations).

- Potential of LeRoi or “Rossland” type gold veins is fairly limited to the northern and southern margins of the Rossland monzonite, (hence the local term “Southbelt” of veins).

- The ski hill on the north face of Red Mountain is underlain by barren (without gold) slates and volcanics.

- All of the gold produced in Rossland came from underground mining methods, with virtually all production coming from within the southeast base of Red Mountain.

- Gold in Rossland  was and still is found in extremely high grade (recovered production was 15 grams gold per tonne of ore rock)  from near vertical and relatively narrow, discreet  veins that dip steeply, with production reaching down to near Columbia river level.

- The industry is now mining grades of gold down to 3 grams gold per tonne underground and fractions of a gram in open pit (where the ore is widely dispersed). The discreet (non dispersed) nature, high grades and great depth of Rossland gold veins are best suited to underground mining methods.

- Regarding the past open pit molybdenite mines on the western slopes of Red Mountain, the ore extracted contained no gold. Gold is found just south of this area but of very high grade and if ever mined, for reasons already stated, would be by traditional underground methods.

If Rossland’s gold industry was to “come to life again,” the geology and location of gold veins favours traditional underground mining methods as well as the City and ski hill.

And who knows, maybe we'll

And who knows, maybe we'll have gold mining again as well one day soon...

Hopefully not!

Any gold remaining here is probably under Rossland and Red mountain, and considering the preferred mining process these days is open pit, it would probably mean losing the namesake to our ski resort, and perhaps Rossland itself.
