Rafaella Resources lands positive ore sorting results for flagship Santa Comba tungsten and tin mine in Spain

Rafaella Resources Ltd (ASX:RFR) has described the ore sorting test results received from Tomra Sorting Solutions for its flagship Santa Comba tungsten and tin mine in Galicia, northwest Spain, as exceptional.

A grade recovery curve shows potential for more than 90% tungsten recovery, with an increased yield of up to 55% of feed mass.

The overall results showed a 50% rejection of unmineralised rock and near doubling of feed grade, lowering planned process capital and operating expenditures, and enhancing process efficiency through a simpler process flow sheet.

Testing of the pre-concentration of Santa Comba ores was highly positive and allows Rafaella to review several opportunities to simplify the process plant thereby reducing capital costs and operating costs for the project.

Testing highly positive


Testing of the pre-concentration of Santa Comba ores was highly positive and allows Rafaella to review several opportunities to simplify the process plant thereby reducing capital costs and operating costs for the project.

Tomra's testing of low-grade ores also showed viable recovery from over 2 million tonnes of mineralisation not currently factored into the projects economics.

Further, the 50% reduction in process tonnage reduces the projects environmental impact, with a far lower volume of waste generated, lower energy consumption per unit of metal produced and lower water consumption

It is estimated that for a throughput of 1 million tonnes of feed ore and around 500,000 tonnes per year of pre-concentrate, two XRT units would be required.

"Exceeds expectations"


Rafaella managing director Steven Turner said: “The results from the ore sorting test-work have exceeded the companys expectations.

“The clear discrimination between ore-bearing rock and low-grade or barren rock has delivered high recoveries and yields allowing for a simpler process plant.

“The benefits of this simplification will be significant once the metallurgical studies are completed.

“These results are now being fed into the feasibility study that is in the final stages of completion and the company looks forward to providing the market with these exciting updates on the fast-tracking of its flagship project over the coming weeks.”

Simplified process plant


The highly positive test results allow Rafaella to review several opportunities to simplify the process plant, thereby reducing capital and operating costs.

Tomra's test program tested two bulk samples selected from assayed drill core crushed to two size groups – +8 millimetres to -20 millimetres and +20 millimetres to -40 millimetres.

Sample No 40 was around 1,100 kilograms of average grade ore at 0.15% tungsten trioxide while sample No 41 was around 250 kilograms of low-grade ore at 0.05% tungsten trioxide.

The reports conclusion was “the results from this test-work were positive for both sizes and samples. Significant upgrades of tungsten trioxide as well as high recoveries were achieved in all test runs for sample '40' usRead More – Source

Argonaut Resources directors show faith in company by participating in oversubscribed SPP

Argonaut Resources NL (ASX:ARE) directors have demonstrated their faith in the company’s copper-zinc strategy by participating in the recently closed share purchase plan (SPP).

Independent non-executive chairman Patrick Elliot purchased more than 4.465 million shares at 0.55 cents per share in an indirect interest.

He now holds 5,876,159 shares in that interest with another 20,324,574 held in a separate indirect interest.

Independent non-executive chairman Malcolm Richmond acquired more than 5.454 million shares in a direct interest, increasing the number held in this interest to almost 15 million with another 1 million held in an indirect interest.

Overwhelming response to SPP[hhmc]
The company was overwhelmed by the response to its SPP which closed early and more than twice oversubscribed with the target subsequently increased to $2.5 million from $1.2 million.

Subscriptions in excess of $3 million were received and as a result, the SPP was closed with immediate effect.

Strickland Metals shares jump 39% ahead of drilling base metal target near DeGrussa

Strickland Metals Ltd (ASX:STK) shares surged 39% today ahead of its maiden drilling program at the Doolgunna Project, which will include a diamond drilling program that is likely to begin by the end of this month.

As a part of the program, a minimum of four diamond holes will be drilled to a depth of 500 metres to test a VMS target similar to the nearby DeGrussa deposit of Sandfire Resources (ASX:SFR).

Heritage survey[hhmc]
Exploration activity has recommenced on the Doolgunna Project following completion of heritage surveys to allow land access to areas where the company wishes to complete exploration drilling.

The target for drilling is a compelling base metal prospect that exhibits geological characteristics that are interpreted to be similar to Sandfire Resources’ DeGrussa deposit about 30 kilometres to the east of the project.

Pan Asia Metals has positive discussions on plans for Thai lithium project

Pan Asia Metals Ltd (ASX:PAM) has had positive discussions with authorities in Phang Nga Province, Thailand, including the provincial government, for its Reung Kiet Lithium Project.

PAM has submitted a presentation covering all aspects of the project including methods of ongoing exploration, conceptual mining and concentrate production, and the potential for downstream value-adding industries in Phang Nga and Thailand.

The presentation and subsequent discussions were aimed at assisting Phang Nga Provincial Government in their considerations for the proposed mining and industrial development areas.

Provincial Government discussions


Pan Asia was recently invited by the chief executive officer of the Phang Nga Provincial Administrative Organisation (PAO), a Phang Nga Provincial Government coordinating body, to represent PAM and the Reung Kiet Lithium Project.

The meeting was also attended by the head of Phang Nga Provincial Industry along with the representatives of the Phang Nga Provincial Public Works and Town Planning Office.

Phang Nga Provincial Industry head has been appointed by the Phang Nga governor as chairman of the Phang Nga New Town Planning Committee.

During the meeting, the chairman of the committee conveyed its support for the Reung Kiet Lithium Project.

PAO wants to ensure that the requirements of the Reung Kiet project are incorporated into the town planning committee’s zoning plans to ensure that the project can progress once exploration and feasibility results prove positive.

“Can bring opportunities”


PAM managing director Paul Lock said: “We have been working hard in Phang Nga province and we are very happy with the positive reception that the Reung Kiet Lithium Project is receiving from the Phang Nga Provincial Government and surrounding communities.

“Reung Kiet is strategically located and based on peer feasibility work the project is positioned to potentially be one of the lowest-cost suppliers of lithium chemicals in the global peer group.

“This is a project that can bring substantial opportunities and value to Phang Nga and Thailand.”

Pan Asia is planning its second Reung Kiet drilling program with expectations that this will begin in the coming months following the conclusion of the current Khao Soon drilling program.

Potential cost curve leader


Reung Kiet is a hard rock project with lepidolite rich pegmatites chiefly composed of quartz, albite and lepidolite with minor cassiterite and tantalite as well as other accessory minerals including some rare earth.

Lepidolite does not require roasting and has a suite of by-products which are recoverable at the concentrator and processing stages of the flow sheet.
