The Nechalacho Rare Earth Elements Project, located primarily at Thor Lake, Northwest Territories, is Avalon's 100% owned flagship project and is recognized internationally for its exceptional wealth of heavy rare earth elements. To view the project Fact Sheet, click here.
As of April 2013, over C$90 million and 108,565 metres of diamond drilling in 502 holes has been completed in exploring and developing the property. With the resource estimation update released in August 2013, estimated Measured and Indicated Mineral Resources for the Basal Zone total 61.90 million tonnes grading 1.64% TREO and 0.35% HREO, with 21.53% HREO/TREO using the base case Net Metal Return (“NMR”) cut-off of US$345/tonne. The updated resource incorporates drill results from the eight-hole winter 2013 drill program and the final 41 holes from the 2012 summer drill program. These holes were not incorporated into the resource model used in the Feasibility Study. Refer to the August 15, 2013 news release for complete disclosure of the individual REE values and other relevant context.
 HREO (Heavy Rare Earth Oxides) is the total concentration of: Y2O3, Eu2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3 and Lu2O3. TREO (Total Rare Earth Oxides) is HREO plus: La2O3, Ce2O3, Pr2O3, Nd2O3 and Sm2O3. HREO/TREO is the percentage proportion of rare earths that are HREO.
Avalon has taken a multi-dimensional approach in terms of the environment and working with local communities, and in 2010, Avalon received PDAC's 2010 Environmental and Social Responsibility Award. Three different MOU’s were signed with the Akaitcho First Nations in 2011 leading to a future cooperative partnership of the Nechalacho Deposit. In June 2012, Avalon entered into an Accomodation Agreement with the Deninu K'ue First Nation.
The definitions that follow are acronyms used throughout the Nechalacho Project section. The list is to aid in reading and understanding the technical content of our website:
- REE = rare earth elements, lanthanum to lutetium by atomic weight plus yttrium
- LREE = light rare earth elements, lanthanum to samarium by atomic weight
- HREE = heavy rare earth elements, europium to lutetium plus yttrium
- TREO = rare earth elements, calculated as oxides, including lanthanum to lutetium plus yttrium
- HREO = heavy rare earth elements, as per HREE above, calculated as oxides
- LREO = light rare earth elements, as per LREE above, calculated as oxides
- NMR = net metallurgical return
- EZC = enriched zirconium concentrate
