Commerce Resources Corp. Samples 5.9% Nb2O5 from the Eldor Property, Northern Quebec

September 13, 2016 – Commerce Resources Corp. (TSXv: CCE, FSE: D7H, OTCQX: CMRZF) (the “Company” or “Commerce”) is pleased to report the results of a prospecting and sampling program completed on the Eldor Property, Northern Quebec. The results of this focused program are extremely encouraging, including the highest niobium mineralized sample collected to date from the area: 5.9% Nb2O5.

In addition to advancing the Company’s Ashram Rare Earth Project, a small prospecting and sampling program was recently completed, which followed-up on the niobium-tantalum-phosphate potential of the Miranna Area, where a mineralized, glacially dispersed boulder train had been previously discovered (see news release dated January 29, 2014). The Miranna Area is located about 1 km east of the Ashram Rare Earth Deposit, which suggests there could be significant potential for development synergies in the event a deposit of merit is defined at Miranna.

The objective of the Miranna program was to further delineate the area’s boulder train in order to better ascertain its bedrock source ahead of drill testing. With the results of this sampling now received, the geometry of the mineralized boulder train is considerably clearer.

The Miranna Area contains a distinct train of niobium-tantalum-phosphate mineralized boulders, which are often large and angular, indicating they have not travelled far from source. Further, the common presence of magnetite in some of the well-mineralized samples suggests the source may have a magnetic signature. Taken collectively, the data indicates that a magnetic high anomaly to the immediate south, which appears to coincide with the boulder train’s apex, may be the bedrock source.


Of the 64 prospecting rock samples collected from the Miranna Area during the program, a total of 40 returned Nb2O5 grades in excess of 0.5%, with 16 in excess of 1% to a peak of 5.9% Nb2O5. In addition, significant grades of tantalum (Ta2O5), phosphate (P2O5), and rare earth oxide (REO) were also returned from the same samples (see Table 1 below).

  4. MH/T is the sum of the middle and heavy rare earth oxides (Eu2O3 + Sm2O+ Gd2O3 + Tb2O3 + Dy2O+ Ho2O3 + Er2O3 + Tm2O+ Yb2O3 + Lu2O+ Y2O3) divided by TREO, expressed as a per cent

All samples were analyzed by Activation Laboratories Ltd. of Ancaster, ON using its method major oxide, rare earths and trace element package by fusion ICP and ICP/MS in addition to tantalum and niobium by XRF.

Miranna is a multi-commodity target area, with high-grade tantalum and phosphate mineralization commonly associated with the niobium. Two samples from the recent program assayed greater than 1,000 ppm Ta2O5 and >1% Nb2O5, with samples often exceeding 10% P2O5. Additionally, appreciable rare earth element mineralization is commonly associated with the niobium and is also enriched in the middle and heavy REOs.

The mineralogy of the Miranna Area samples is highly favourable. Previous mineralogical work on the carbonatite complex indicates that the niobium and tantalum mineralization present is hosted by the mineral pyrochlore, which is the dominant mineral source of niobium globally. Further, much of the pyrochlore is visible to the naked eye, thus indicating a relatively course grain size which is advantageous to metallurgical recovery.

The Ashram Deposit was discovered using the same exploration principles currently being applied at Miranna, that being the effective identification and tracing of a well-mineralized, glacially dispersed boulder train back to its bedrock source. With the postulated source of the Miranna Area boulder train now further delineated, the next step is drill testing.

About Tantalum and Niobium
Tantalum is a niche commodity that dramatically improves performance of high-tech devices. The element is critical to miniaturization and efficiency of cell phones and similar products and is essentially found in every electronic device produced on the planet. It may not be required in large amounts but is absolutely essential to the electronics industry.

Niobium is commonly marketed as ferroniobium and is used dominantly as an additive in high-strength low-alloy steel production. The addition of up to 0.1% niobium will considerably enhance the strength of the final product and is a critical component to steel production globally.

About Commerce Resources Corp.
Commerce Resources Corp. is an exploration and development company with a particular focus on deposits of rare metals and rare earth elements. The Company is focused on the development of its Upper Fir Tantalum and Niobium Deposit in British Columbia and the Ashram Rare Earth Element Deposit in Quebec.
