Bedrock pit geochemical samples returned a peak result of 5.57% total rare earth oxides, including 1.17% neodymium oxide.
The rock chip program returned the best sample yet, with 7.12% total rare earth oxides. The results indicate the presence of extensive rare earth element mineralisation within the soil anomaly, which covers 3.5 kilometres by 1.7 kilometres.
A surface geochemical program in 2011 confirmed bedrock sources throughout the soil anomaly area, with a peak result of 18.96% total rare earth oxides in bedrock pit samples.
Black Fire is planning an aggressive exploration program at Longonjo in 2012, comprising will comprise aircore and reverse circulation drilling programs at the Longonjo prospect and geochemical screening over the entire project area for base metals and gold.
Chairman Anthony Baillieu said: "The board is very pleased with the latest results from the Longonjo REE Prospect which have continued to provide considerable encouragement regarding the potential significance of this prospect.
"The company continues to negotiate with potential drilling contractors and looks forward to being able to announce the commencement of drilling at this exciting target in due course."
Black Fire's Longonjo Project covers 3,670 square kilometres in central Angola, about 600 kilometres southeast from the country's capital city of Luanda.
It comprises the Longonjo Rare Earth prospect as well as prospectivity for gold and base metals. Rock chip assays have of up to 9% copper and 6 grams per tonne gold have been returned.
Importantly, the project is well located in regards to infrastructure, including road networks and a recently recommissioned railway linking the area to the Atlantic port of Benguela/Lobito which passes less than 3 kilometres from the Longonjo rare earth prospect.
Black Fire entered an Option to Purchase agreement to acquire a 70% interest in the Longonjo project with Sable Minerals in June 2011.
