Assay Results Show High Grades of Tungsten Oxide (WO3) and Drilling Finds New Mineralisation at RHA Tungsten Project, Zimbabwe  

 

Premier African Minerals Limited, the AIM traded, multi-commodity natural resource company with mineral projects located in Western and Southern Africa, provides an update on assay results from its recently completed drilling programme at the RHA Tungsten Project ('RHA'), Zimbabwe, in which Premier is the operator and holds a 49 per cent interest.

 

The additional drilling of Lode 2A, as recommended in the Preliminary Economic Assessment was completed in December 2013. The announcements dated 28 August 2013, 2 December 2013 and 8 January 2014 set out details of this. Assay results from boreholes DD09, DD10, DD11, DD12, DD13 and DD14 have been received and are set out below. In all holes, the Lode 2A mineralised zone has been intersected, providing confidence and continuity to the previously announced resource.

 

All holes have intersected previously unknown additional mineralisation in the Hanging Wall (HW) and in the case of DD10 and DD13, also in the Foot Wall (FW). Inspection of the results and significantly of the Composites reveals very high grade mineralisation of up to 359 kilograms per tonne WO3 in assay and 154 kilograms per tonne WO3 in Composite (DD09 Vein K).

 

Best assays to date are:         142 kilograms per tonne (DD07 Vein 1)

                                                159 kilograms per tonne (DD11 Vein C)

                                                359 kilograms per tonne (DD09 Vein K)

 

Results are tabulated as received and the resource model is being updated accordingly.

 

George Roach, CEO, commented that "The RHA deposit continues to impress not only in the continuity of the Lode 2A mineralisation but now also in impressive new discoveries. Despite this, the company is focussed on tabulation of all remaining results and the updating of the resource model as a priority. Further updates will follow in the near term."

Glossary of Technical Terms

"Composites"are weighted lineal averages where applicable.

 

"Measured mineral resource" is that part of a mineral resource for which quantity, grade or quality, densities, shape, and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit.  The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

 

"Mineral resource" is a concentration or occurrence of diamonds, natural solid inorganic material or natural fossilized organic material including base and precious metals, coal, and industrial minerals in or on the Earth's crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge.

 

(Fe,Mn) WO₄ is a chemical composition of wolframite.

 

"Mineralisation" is the presence of a target mineral in a mass of host rock.

 

"Tungsten" is a metallic element known as wolfram with a symbol of W and an atomic number of 74.

 

"Veins" are a tabular or sheet like body of one or more minerals deposited in openings of fissures, joints or faults, frequently with associated replacement of the host rock.

 

"Wolframite"is the mineral name for iron-manganese tungstate; (Fe,Mn)WO_4, an ore of tungsten. The ratio of iron to manganese varies; iron-rich wolframite is known as ferberite FeWO₄, manganese-rich wolframite is known as hubnerite MnWO_4.

 

"WO3" Tungsten oxide, also known as tungsten trioxide or tungstic anhydride, WO3, is a chemical compound containing oxygen and the transition metal tungsten. It is obtained as an intermediate in the recovery of tungsten from its minerals.
