King River Resources updates Speewah Project PFS to focus on smaller scale development

King River Resources Ltd (ASX:KRR) has revealed an update to the Speewah Specialty Metals (SSM) Project PFS after sulphuric acid leach testwork on magnetite concentrate, non-magnetic concentrate fractions and run of mine rock support the potential of a smaller scale project development design.

The new plan would mean alumina is primarily targeted and extracted by leaching rock that has only been mined, crushed and ground to 0.15mm without further beneficiation.

These changes to focus on high purity alumina (HPA), vanadium pentoxide (V2O5), titanium dioxide pigment (TiO2) and iron oxide (Fe2O3) products in a smaller scaled operation may provide a basis for its future scale-up to produce more products in proportion to prices and demand.

HPA extraction methods

Late last year, King River made a breakthrough in extracting aluminium directly from the vanadium, titanium, iron, aluminium and magnesium rich sulphuric acid lead solution as the first precipitation product from which 99.98% aluminium oxide HPA was produced by a new process.

The company is now progressing flowsheet development of its new process to make HPA, and the extraction of the vanadium pentoxide, titanium dioxide pigment, and iron oxide by conventional solvent extraction methods.

HPA test work has focussed on simplifying the process steps to improve aluminium recovery and ensure the lowest level of contaminants.

The drill core samples tested are from a high-grade zone, ground to 0.15 millimetres, leached in 20% sulphuric acid at 70°C and 20, 30% and 35% pulp densities, for 96 hours.

This has enabled King River to select leaching of whole rock magnetite gabbro as the preferred initial design for a small-scale operation that delivers the optimal amount of HPA.

Further leach test work is planned to try to increase the aluminium extraction to greater than 50% by reducing the grind size and extending the leach time.

Director comments

KRR continues to make very positive steps forward towards identifying the most prudent process route and scale for the Speewah Specialty Metals (SSM) Project.

Pure Minerals receives coverage from Independent Investment Research

Pure Minerals Ltd (ASX:PM1) has received research coverage from Independent Investment Research (IIR).

The 22-page report goes into detail regarding the proposed Townsville Energy Chemical Hub (TECH) Project in Queensland.

The report notes the building blocks are coming together quickly for the TECH Project with the pre-feasibility study (PFS) completed in December 2019 as well as the recently completed high purity alumina (HPA) scoping study.

Share price at deep discount to project's estimated NPV[hhmc]
Using a share price of 1.9 cents, the company has a market capitalisation of $16.1 million.

While the report does not designate a share price target, it does estimate a net present valuation (NPV) for the proposed TECH Project of between $47 million and $585 million.

The research firm does note the valuation relies on a number of factors including PFS assumptions and project approvals.

The following is an extract from the report:

VALUATION VERY SENSITIVE, BUT PRICE TREND POSITIVE

If we include the deferred consideration shares, Pure Minerals at A$0.019/sh would have a market capitalization of A$16.1M. Our NPV for the NiCo plant ranges from A$47M using the cycle price lows of the last three years to A$585M using cycle price highs over the last three years, and A$241M assuming current spot prices flat in real terms forever. The HPA bolt-on is additional value. These valuations are for the project only, and take no account of the cost of corporate overheads, nor of financing diRead More – Source

Pure Minerals gains new substantial holder in managing director John Downie

Pure Minerals Ltd (ASX:PM1) has gained a new substantial holder in managing director John Downie.

Downie now holds 40.78 million shares increasing his stake in the company to 6.83%.

High-purity alumina (HPA) scoping study adds value[hhmc]
Pure recently received results for a scoping study evaluating the production of high-purity alumina (HPA) from its Townsville Energy Chemicals Hub (TECH) Project in Queensland.

The scoping study assessed the production of 4N HPA on a standalone basis, using the aluminium hydroxide as a feedstock.

This scoping study followed the December 2019 pre-feasibility study (PFS) on the TECH Project which identified the production of HPA as a key value-add opportunity for the project.
