DIOS finds several Rare Earth Element zones in Shipshaw Carbonatite Complex

MONTREAL, QUEBEC, CANADA – DIOS EXPLORATION INC. intersected several Rare Earth Element mineralized zones in the first hole completed on the Shipshaw Carbonatite Complex, Saguenay, Quebec, located roughly seven kilometers away from the niobium mine and ferro-niobium facilities owned by IAMGOLD.  Niobium values were also returned from a batch of some 90 samples, reaching 0.053 % Nb2O5 (niobium oxide) over 1.5 m at this stage with high grade apatite content (12 % P2O5 (phosphate) and 0.487% TREEO (total rare earth element oxides, excluding yttrium and zirconium). Several other apatite rich zones were also intercepted.

The upper alkaline complex syenite horizon was reached at less then 17 m and returned  0.70% TREEO and 9.25 % P2O5 (very high apatite content) over 0.82 m (with 0.4 11% strontium) , included within a 10.54 m horizon grading 0.172% TREEO, then followed by 0.3% TREEO over 8 m in a carbonatite sensu stricto horizon returning 0.26% TREEO over 12.27 m.

Values in P2O5 in carbonatite reached for instance 2.42 % over 3 m at a shallow vertical depth of 27 m, then at a depth of 32 m a further 7.4 m at 3 % including 4.27 % over  3 m.

This first hole was drilled almost vertically in the lowest magnetic part of the anomaly with only 6 meters of overburden above some eleven meters of Ordovician sediments lying above the alkaline complex.  Interestingly, the lower 2 meters of the sediments even returned niobium and rare earth elements with 0.022 % Nb2O5, 0.228% TREEO and 0.253 % ZrO2 (zirconium oxide).

Work completed to date confirm the discovery by DIOS of a sister complex to Niobec, its footprint bearing several similarities with Niobec.  Exploration work by DIOS is actually at the same stage as Niobec a few months after discovery of the rare earth core.  Some 15-20 drill holes are planned and will be required at least to fully evaluate the potential for niobium, tantalum and other commodities of  the Shipshaw Carbonatite Complex of DIOS.

The deposit model that DIOS is looking for is of the same complex type than Niobec’s carbonatite, a sheeted dyke complex, therefore horizon alternation. Historical data shows that the Niobec discovery was first made through the center of the complex, the rare earth carbonatite, and then, with the help of extensive drilling, the niobium bearing zones were established in economical quantities, in the horizon surrounding the rare earth core.

All core was splitted in two halves and core samples averaging one meter long each were sent out to Actlabs, Ontario, Canada, for assaying with the help of several methods, including XRF, ICP-MS, INAA, etc., considering the variety of elements encountered.  Usual quality control procedures were implemented, including the use of duplicates, standards and blanks.

Several other sample batch results are awaited for and new results should be released in the weeks to come.
