Dangerous Minerals

Coloradoite is a mercury telluride compound formed when mercury fuses with tellurium, another extremely toxic and rare metal.

The combination of the two elements poses the risk of serious poisoning. If heated or chemically altered, deadly vapor and dust is released. Tellurium minerals may combine with gold. The streets of Kalgoorie in Australia were mined in a bizarre gold rush after the realization that gold-bearing tellurides had been used to fill potholes.
Chalcanthite crystals are composed of copper, combined with sulfur and other elements and water. This arrangement turns copper into an extremely bio-available crystal.

The copper becomes water soluble, and may be assimilated in great quantities by any plant or animal, rapidly weakening it and then killing it.
Hutchinsonite is a hazardous mixture of thallium, lead and arsenic. The three poisonous metals form a lethal mineral cocktail.

Thallium is the dark twin of lead. This thick, greasy metal is similar in atomic mass but even more deadly. Thallium is a rare metal that appears in highly toxic compounds consisting of combinations of elements. The effects of thallium exposure include loss of hair, serious illness through skin contact and in many cases, death.
Galena is the principle ore of lead, and forms glistening silver cubes with almost unnaturally perfect shapes. Although lead is normally extremely flexible, the sulfur content of galena makes it brittle and reactive. Galena may lead to lead dust exposure.

Once extracted, the lead content poses environmental and health threats during treatment and extraction. Galena has a cubic fracture, and if hit with a hammer, the crystal will shatter into multiple smaller replicas of its original shape.
Asbestos is a fully natural category of minerals composed of silica, and the most abundant of Earth’s hard elements, iron, sodium and oxygen. Asbestos deposits consist of aggregates of thousands of tiny, fibrous crystals that can become airborne and lodged in the human lung. Carcinogenic effects occur through persistent irritation of the lung tissues, leading to scarring.
Arsenopyrite is arsenic iron sulfide, which is the same type of mineral as pyrite (fool’s gold, iron sulfide), but with a heavy addition of arsenic. If one attempts to heat or alter the mineral, a strong garlic odor of arsenic will be produced as lethally toxic, corrosive and carcinogenic vapors are released. Just handling the mineral brings one into contact with sulfuric arsenic salts.
Torbernite crystals form as secondary deposits in granitic rocks, and are composed of uranium. Formed through a complex reaction between phosphorous, copper, water and uranium, the crystal releases lethal radon gas.

The bright green crystal blooms were used by prospectors as indicators of uranium deposits.

Greenland Ruby

Gemstones have been found in Greenland, including diamond, ruby, sapphire, kornerupine, tugtupite, lapis lazuli, amazonite, peridot, quartz, spinel, topaz, and tourmaline.
Most of Greenland's ruby and sapphire occurrences are located near the village of Fiskenaesset on the southwest coast.
A total of 31 ruby and sapphire occurrences have been confirmed in the Fiskenaesset district. The Aappattuloq Ruby project was being developed by True North Gems Inc. The company recently announced financial problems with the project being sold.
Ruby and pink sapphire rough has been recovered. The bulk of the material is rather small, with 90% (by weight) measuring less than a quarter inch (6.3mm). The quality of the rough raises hopes that Greenland Ruby might play an important role on the world gem markets in the future.

The largest gem facetted to date weighed 0.69cts and was evaluated at $ 2.100,00 (US wholesale).

In May 2011 an initial resource calculation was announced for Aappaluttoq. The resource included indicated resources of 189,150 tonnes of material hosting 59 million grams (296 million carats) of corundum and inferred a further 21 million grams (109 million carats) to a depth of 65m.

The resource is National Instrument 43-101 compliant and is the first coloured gemstone resource ever to be published under these laws.

LNS says it expects the first rubies from Greenland’s Aappaluttoq mine to be on the market by January.
Norway’s LNS was a junior partner in the project, responsible primarily for building the mine for True North Gems. LNS saw its opportunity to take over completion of Aappaluttoq after True North Gems failed to raise the final $15 million it needed. The board voted to ask the court in Nuuk to declare the operation bankrupt in order to avoid being made liable for eventual losses.

LNS continued to see potential in the mine, and it put in a bid to take the mining licences.

Montepuez ruby mine, Mozambique

The Montepuez ruby deposit is located in the northeast of Mozambique. Covering 33,600 hectares, it is the most significant recently discovered ruby deposit in the world.

The concession is located at a geologically critical junction between the north-south trending Mozambique Belt and the east-west trending Zambezi Belt. Both are “treasure-bearing” Neoproterozoic orogenic belts within the global Pan-African tectonic framework.

Estimates of probable ore reserves are 432 million carats at a diluted grade of 15.7 carats per tonne.
Gemfields PlC (LON:GEM) announced last year that Montepuez has enough reserves to last 21 years. Rubies are formed when fluid derived from the parental magma interacted with the host rocks under a silica unsaturated environment. After hundreds of millions years of erosion, rubies are liberated from the host rock and transported and concentrated by water and eventually settled in alluvial, colluvial, and eluvial deposits.
At its inaugural June 2014 auction of ruby and corundum Montepuez ruby achieved $33.5 million or an average $18.43 per carat with 92 percent sold by lot.

The auction saw 2.03 million carats of ruby and corundum placed on offer, of which 1.82 million carats were sold.

If this is the case, the stone could yield a cut and polished ruby with a wholesale value of $1.5 million or more.
In November 2015 Gemfields discovered a 40.23-carat ruby at Montepuez which it has called “one of the most important rubies unearthed in recent times”

While the yield from the rough varies, one may assume 30 to 40 percent. This should provide a 12 to 16 carat gem. The question is how clean the stone is and if it requires heat treatment. A clean stone without heat treatment is more valuable.
The stone is significant because it attests to the mine’s ability to produce important rubies.

Due to the rarity of rubies, the discovery of a 40-carat ruby is comparable to finding a 100-carat rough diamond.

Critical Elements Corporation - CRE.v

Critical Elements Corporation - CRE.v is advancing the flagship Rose Lithium-Tantalum project in Quebec.

A PEA on the project suggests an IRR of 25%, with an estimated Net Present Value (NPV) of CA$279 million at an 8% discount rate. The payback period is estimated at 4.1 years.





On February 13, 2017 the media released News

The Globe and Mail reports in its Saturday, Feb. 11, edition that Critical Elements (70 cents) wants to advance its Rose lithium-tantalum project through the feasibility stage. The Globe's Ted Dixon writes in the Who's Buying and Selling column that last June, Critical Elements tapped Helm AG for a credit facility of up to $4.5-million. Helm also gets an option to acquire up to 25-per-cent ownership in the project by paying for a portion of the mine construction. In November, Critical Elements hired Steffen Haber as its president. So far, Mr. Haber has spent $226,695 buying stock in the market even as the share price was rallying toward multiyear highs.
