The Eldor Property is at a relatively early stage of exploration with historic exploration results indicating considerable potential for carbonatite-hosted niobium and tantalum mineralization. Following its acquisition from Virginia Mines Inc. in 2007, Commerce Resources completed a comprehensive exploration program to confirm the historic mineralization at the property.
The Eldor Carbonatite is similar in size to, or slightly larger than, the present and past producing Canadian carbonatite complexes Oka, and St. Honore, both located in Quebec. It is also comparable in size to the Araxa Carbonatite Complex in Brazil, which is about 4.5 kilometers in diameter.

Technical Report
There is currently no National Instrument 43-101 report on the Eldor Property, nor are there proven, indicated or inferred resources.
History of Exploration
The Eldor Property was discovered in the early 1980s by Eldor Resources Limited ("Eldor") during regional exploration fueled by the uranium boom in nearby Kitts-Michelin, Labrador. Eldor's work included lake sediment sampling and airborne radiometrics surveys followed by prospecting, mapping and rock chip sampling.
The Eldor Property came to the attention of Unocal Canada Ltd. ("Unocal") in 1983 who obtained and reanalyzed Eldor's rock samples to confirm the up to 4.1% niobium and 0.15% tantalum values reported. The samples were also studied petrographically, and identified as sovites (calcitic carbonatites) and beforsites (dolomitic carbonatites) containing pyrochlore and columbite.
In 1985-86, Unocal conducted a brief field program over the same area to further evaluate the historical showings, and to determine the potential of the carbonatite to host a significant niobium deposit. Exploration consisted of rock chip sampling, prospecting, and soil and radiometric surveys, followed by mineralogical and petrological investigations. Thirty rock samples and sixty-three soil samples were taken for analysis.
In 2001, Virginia Mines Inc. ("Virginia Mines") carried out four days of reconnaissance geology and rock sampling.
The Eldor Carbonatite, from work completed by Eldor, Unocal, and Virginia Mines Inc., has niobium and tantalum mineralization that ranges from 1.15% Nb205 and 0.046% Ta205 up to 11.4% Nb205 and 0.21% Ta205.
