Eclipse Metals Ltd Ivittuut Bulk Sample Analysis Returns 99.9% Silica

“The identification of rare heavy REEs, rare critical metals and high purity quartz cemented our conclusion on the uniqueness of the polymetallic nature of the Ivittuut pit enclosure,” said Executive Chairman Carl Popal. .

Eclipse Metals Ltd (ASX:EPM) confirms that recent laboratory analysis of a quartz bulk sample from its Ivittuut multi-product project in southwest Greenland returned high silica and low impurity content.

The multi-kilogram sample of quartz was taken from historic mining dumps and shipped to Perth, Western Australia, for analysis.

Additional simple purification possible

Close analysis of quartz reveals that it can be further purified with a simple acid washing process to dramatically increase quality by removing impurities.

This makes it potentially suitable for the high-tech semiconductor industry, further increasing the value of the deposit.

Results from this bulk sample confirm results previously reported by North Atlantic Mining Associates.

Eclipse Metals Executive Chairman, Carl Popal, said, “Our assessment of historical data has revealed tremendous economic potential at Ivittuut, being the world’s only known commercial mine of natural cryolite, but with the potential to be a multi-product.

Modeling of historical exploration data from the Ivittuut deposit indicates the presence of a large cylindrical body of high silica, low impurity in situ quartz immediately below the floor of the pit, as defined by historical drilling.

High-grade silica quartz recovered at Ivittuut.

Significant economic opportunity

The modelling, which supports an estimated exploration target of between 5.70 million tonnes and 5.94 million tonnes of quartz varying between 90%, confirms the Company’s view of the significant economic potential of exploiting this body of high silica quartz.

Historical assays of individual quartz intersections have returned high grades ranging from 99.02 to 99.98% silica and historical average drill intersections include:

  • 54 meters at 97.6% silica from 32 meters;
  • 24 meters at 93.2% silica from 12 meters; and
  • 53 meters at 94.8% silica from 45 meters.

Eclipse has defined an exploration target for high silica quartz at Ivittuut, and has further exploration plans underway, to prepare an initial JORC 2012 compliant resource estimate for the quartz body at Ivittuut, scheduled for the second half of the year.

Growth of the global quartz market

The global quartz market is expected to reach $13.61 billion by 2026 growing at a compound annual growth rate of 6.9% from 2020 to 2030 according to Persistence Market Research.

“Our recent sampling program verified the potential of Ivittuut and Grønnedal-Ika to host rare earth element (REE) mineralization as well as base and critical metals, and has now confirmed a quantifiable mass of quartz at low impurity containing up to 99.9% silica,” said Popal.

“The identification of rare heavy REEs, rare critical metals and high purity quartz cemented our conclusion on the uniqueness of the polymetallic nature of the Ivittuut pit enclosure.

“Overall, recent exploration results have highlighted the potential for much of the mineralization in the pit to have economic value, enhancing the economic potential for redevelopment of this mine.”
