Rift Valley Resources Limited: Initial Drilling Programme has Commenced on Longonjo Ree Project

| January 24, 2014 | No Comments

January 24, 2014 (Source: Rift Valley Resources Limited) — Highlights:

  • Rift Valley is pleased to announce the commencement  of drilling on Longonjo REE, The first prospect to be advanced within its newly acquired Ozango Project in Angola.
  • The first pass drilling programme at Longonjo aims to test the bedrock mineralization  beneath a substantial soil anomaly as well as provide the sample material for an initial metallurgical assessment.
  • The Longonjo REE Prospect is currently defined by a large 3.5km long and 1.7km  wide  +0.5%  REE soil anomaly  peaking  at +5%  total  rare earth oxide (TREO).
  • A follow up trenching and pitting programme within the geochemical anomaly returned TREO grades up to 18.9% in bedrock pit samples. No drilling has yet been undertaken on the prospect.
  • In addition, Longonjo hosts significant niobium with assays peaking at 0.76% Nb2O3, and phosphate with assays peaking at 7.45% P2O5 and boasts  low  uranium  (avg.  <25ppm)  and  thorium  (avg.  <850ppm) levels.
  • The project is well located in relation to infrastructure  including the regional city of Huambo. The national highway and the recently recommissioned railway to the port of Lobito pass less than 3km from the Longonjo REE Prospect.

Background Information

The Longonjo REE prospect is located within the Ozango Project, approximately 600km southeast of the Angolan capital Luanda and 50km west of the regional city of Huambo. It is located proximal to good infrastructure including roads, towns and the recently recommissioned railway which links the area to the deep water Atlantic port of Lobito.

The Project area covers some 3,670km2  of Archaean/Palaeoproterozoic  greenstone  rocks that have been intruded by Cretaceous felsic volcanics, carbonatites and kimberlites.  These rocks are considered highly prospective for REE, phosphate, copper, iron ore and gold.  To date, however, this area has seen very little modern exploration.

The Longonjo REE prospect is the first target within the Ozango Project to be drill tes ted by Rift Valley.   Located near the town of Longonjo in the north-central portion of the Project area the prospect centers on a Cretaceous age, carbonatite intrusive.  The geology is typical of REE mines and prospects globally including Lynas Corp’s Mt Weld deposit in Western Australia and Peak Resources’ Ngualla deposit in Tanzania.

A soil geochemical sampling program undertaken at Longonjo over an area of 8km2 defined a large and robust 3.5km long and 1.7km wide +0.5% REO anomaly which remains open to the west.  A follow up trenching and pitting program carried out to test the bedrock within the soil anomaly  returned  highly  encouraging  results  of up to 18.9%  TREO  from  the pit bedrock samples.   The drilling program aims to test the subsurface mineralization and will also provide sufficient sample for an initial metallurgical assessment to be carried out.


We  advise  in  accordance  with  Australian  Stock  Exchange  Limited  Listing  Rules  5(6)  that  the  exploration  results contained  within this ASX Release  is based on information  compiled  by Mr Greg Cunnold  who is a member  of the Australian Institute of Mining and Metallurgy. Mr Cunnold is not an employee of Rift Valley Resources Ltd and has consented in writing to the inclusion in this ASX Release of matter based on the information so compiled by him in the form and context in which it appears. Mr Cunnold has sufficient experience relevant to the style of mineralisation  and type of deposit under consideration to be qualified as a Competent Person as defined by the 2004 Edition of the “Australian Code for reporting of Exploration Results, Mineral Resources and Ore Reserves”.
