Granada Gold (TSX.V: GGM) has identified a massive Rare Earth Metals zone within the Big Claim of the Granada Gold Mine property, in Quebec, Canada.
Results are preliminary and full core lengths have not yet been assayed in two holes drilled at the north of the Big Claim. The company encountered unusual facies of altered rock which has been sampled in portions of the drill core. The mineralized portions of the core have been assayed for 56 metals. Additional assays are pending. Initially, portions of drill holes GR-20-20 and GR-20-22 were sampled. The company has received preliminary assay results for GR-20-22. Based on recent assays for intervals sampled, the intervening intervals are being prepared and will be sent for assay to create a complete picture.
Highlights of drill hole GR-20-22 as of today:
- Intercepted 21 distinct mineralized zones.
- Zones range in core length from 177 meters to 2.8 meters.
- Rare Earths and Alkali metals of note identified to date are Caesium (Cs), Rubidium (Rb), Scandium (Sc), Zirconium (Zr), Cerium (Ce), Gallium (Ga), Hafnium (Hf), Neodymium (Nd) and Strontium (Sr). Others pending.
Why Rare Earth and Alkali Metals?
Rare Earth Elements are taking off amid at the Biden Administration undertaking swift reviews of key U.S. supply chain vulnerabilities. President Biden discussed the manufacturing base and mentioned, “key minerals and materials, like rare earths, that are used to make everything from harder steel to airplanes.” The Executive Order requires an immediate 100-day review of U.S. supply chains for four key products, including APIs for pharmaceuticals, rare earth elements, semiconductors and advanced packaging, and large capacity batteries. Multiple federal agencies will develop comprehensive supply chain assessments of goods and materials critical to national and economic security and for which shortages or global competition affect supply. USA Rare Earth’s Round Top deposit hosts the full range of rare earths and lithium for large capacity batteries and electric vehicle batteries, and also U.S. Government-listed Critical Minerals zirconium, hafnium and gallium, which are required for next-generation semiconductor manufacturing.
Caesium is used to make special optical glass, as a catalyst promoter, in vacuum tubes and in radiation monitoring equipment. One of its most important uses is in the ‘caesium clock' , or atomic clock. (Royal Society of Chemistry) with a price of 68,100 US dollars per kilogram (Mineral Commodity Summaries 2019).
Rubidium’s photoemissive properties make it useful for electrical-signal generators in motion-sensor devices, night vision devices, photoelectric cells (solar panels), and photomultiplier tubes. Rubidium is used as an atomic resonance-frequency-reference oscillator for telecommunications network synchronization, playing a vital role in global positioning systems with prices of 15,500 US dollars per kilogram (USGS Mineral Commodity Summaries 2019).
Scandium is one of the most expensive of all the natural elements. Prices for 99.99% pure scandium (RE: 99% min. | Sc/TREM: 99.99% min.) have fluctuated between US$ 7000 and US$ 20,000 per kilogram over the past decade. Of course, because of the limited amount of material produced globally and the limited market for scandium, there is also a wide range of prices offered for the metal at any given time (strategic-metal.com and phone conversation May 10, 2021). Applications for scandium were not developed until the 1970s, when the positive effects of scandium on aluminum alloys were discovered, and its use in such alloys remains its only major application.
Cerium metal is used in ferrocerium lighters for its pyrophoric properties. Cerium-doped YAG phosphor is used in conjunction with blue light-emitting diodes to produce white light in most commercial white LED light sources. Recent prices are 4.71 US dollars per kilogram (Shanghai Metals Market, cerium).
Gallium as an arsenide is used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells and optical windows with a price of 534.4 US dollars per kilogram (kitco.com strategic-metals).
The leading use of hafnium metal is in super alloys with a price of 1347.4 US dollars per kilogram (kitco.com strategic-metals).
Neodymium is as a component in the alloys used to make high-strength neodymium magnets—powerful permanent magnets. These magnets are widely used in such products as microphones, professional loudspeakers, in-ear headphones, high performance hobby DC electric motors, and computer hard disks, where low magnet mass (or volume) or strong magnetic fields are required. Larger neodymium magnets are used in high-power-versus-weight electric motors (for example in hybrid cars) and generators (for example aircraft and wind turbine electric generators). Price is 118.5 US dollars per kilogram (kitco.com strategic-metals).
Processing and Refining Rare Earths and Alkali Metals
Conventional mining, milling, separations and finishing possible at a single site with a zero discharge. Mountain Pass Mine in California, USA, which is in operation now is producing rare earth metals.
“Granada’s rare earth and alkali metal discovery was encountered during our deep drilling program for gold on the defined gold zone that is dipping at 50 degrees to the north towards the renowned Cadillac Break. Our target depth for the gold mineralization extension in the north of the Big Claim is about 2,500 meters,” said Frank J. Basa, P.Eng., “The 1.6 kilometer step out along the Cadillac Break could potentially be a massive rare earth and alkali metals mineralized zone yet to be discovered which would greatly impact the value of the property. The company has 5.5 kilometers of east-west strike length to further explore along the Cadillac Break. Drill results to date are exceptionally encouraging.”
The company is taking action on characterizing the minerals of these elements. It has sent samples to SGS Minerals in Ontario for advanced mineral analysis under the direction of Tassos Grammatikopoulos, Mineralogist at SGS Lakefield Research
Results to date are from SGS independent laboratories where NQ core samples of hole GR-20-22 were analysed. The company will proceed with sampling of the entire hole to enable disclosure of mineralized lengths associated with grades as well as investigation on the mineralogy as the grades of interest are not confined to one geological unit.
Co-ordinates of the hole have been determined by handheld GPS and will be surveyed in spring.
