Surefire (ASX:SRN) reports “significant anomalous” rare earth results at Perenjori - Kalkine Media

Highlights

• Surefire (ASX:SRN) is advancing work at its Perenjori Iron tenement E70/5311.
• Total 17 samples were collected from lithologies within the exploration tenement during a reconnaissance site visit in December 2022.
• The results from the sampling of newly discovered pegmatites are significantly anomalous, indicating up to 345ppm total rare earth oxides.
• The south-eastern portion of the tenement hosts a historical kaolin occurrence, while additional kaolin occurrences have been noted in outcrop.
• Comprehensive environmental survey is in progress.

Surefire Resources NL (ASX:SRN) has shared an update on latest activities progressing at its Perenjori Iron tenement E70/5311. 

In December 2022, a total of 17 samples were collected from lithologies within the company’s exploration tenement during a reconnaissance site visit. These lithologies were present at locations peripheral to the Perenjori Iron resource. 

According to the company, the results from the sampling of newly discovered pegmatites on the property are significantly anomalous with a maximum of 345ppm Total Rare Earth Oxides (TREO) in sample PI Peg001. Also, anomalous TREO values were noted from additional sampling in the vicinity of the pegmatite, and elsewhere on the tenement.

Insights into the findings

Surefire discovered pegmatites on the eastern periphery of a kaolinised sheared granite contact between the sediments, hosting the Perenjori Iron deposit, and an intruded granite stock to the east. As per the results, the rare earth elements are present in the pegmatites within the granitoid, the sheared kaolinised granite/sediment contact zone, or all the above.

The south-eastern portion of the tenement hosts a historical kaolin occurrence and additional kaolin occurrences have been noted in outcrop within the Surefire tenements during the reconnaissance field trip.

Within Australia and overseas, Kaolin has won recognition as a host for rare earth mineralisation. Kaolin has become a primary source for production of high purity alumina (HPA) for use in lithium-ion batteries. 4HPA is a high-value product currently valued at approximately AUD30,000/t.

Follow Up Work Program

Sample PI 005-1 A highly micaceous rock which produced an assay grading 267.2ppm TREO and 1930ppm Rb2O

Going forward, the ASX-listed company plans to conduct GIS review of the aeromagnetic imagery, detailed geological mapping, local geochemistry as well as follow up shallow drill testing to explore the kaolin and pegmatites occurrences at Perenjori.

The Perenjori Iron BIF (Banded Iron Formations) has been the historical focus of aeromagnetic interpretation. According to the review of aeromagnetic data, the pegmatites are structurally controlled and that additional similar trending repetitions may take place within the current EL and the new EL in application.

Comprehensive Environmental Survey in progress

A comprehensive flora and vegetation database review was conducted by environmental consultants for the Banded Iron Formations (BIF) on the tenement. This review is essential in order to get a Program of Work (POW) for the planned 6,000m infill RC drilling campaign. The detailed report is expected by early February 2023.

The drilling campaign is planned to provide the basis for a resource upgrade and an economic prefeasibility study as an update from the previous scoping study.
