Forrestania Resources logs ‘exciting’ lithium results at namesake project in WA

Forrestania Resources (ASX:FRS) reports assays results have been returned from its lithium-focused reverse circulation (RC) drilling program at its namesake project in Western Australia.

The company says 5 holes were completed at the Giant Pegmatite within its Forrestania Lithium Project, which focused on determining the extent of the mineralised pegmatite intersected in historical drilling, and returned an intercept of 34m @ 3.1% Li2O from 68m.

Drillhole FGIR0004 returned 10m @ 1.49% Li2O from 74m including 2m @ 2.64% Li2O from 75m. This hole is located over 25m along strike to the northwest from the aforementioned discovery intercept.

It is always exciting to drill high-grade intersections and we are confident there is potential for more at Gian”

Forrestania says the host mineral of the ‘high-grade’ lithium is not yet known, and samples will be forwarded for spectral analysis to determine this. Notably, the company’s geologists did not observe lepidolite within the drill samples.

Other intercepts recorded at Giant Pegmatite include FGIR0002 with 4m @ 1,106 parts per million (ppm) tantalum (Ta) from 45m including 1m @ 2,870ppm Ta; FGIR0003 with 6m @ 0.28% Li2O from 66m including 2m @ 0.43% Li2O and 1m @ 0.51% Li2O; and FGIR0005 with 8m @ 0.17% Li2O from 111m including 1m @ 0.42% Li2O.

Forrestania reports this drilling program has extended the pocket of known ‘high-grade’ lithium mineralisation, confirmed the continuity of the Giant Pegmatite, and confirmed the consistency of lithium anomalism and prospective geochemistry. The company interpreted that mineralisation within the pegmatite is zoned and notes there may be further pockets of ‘high-grade’ lithium mineralisation along strike of the body.

The company also says there is a ‘significant’, untested section in between the 2 drilling areas where a dolerite dyke is interpreted to occur based on regional geophysics. This however is not at all constrained or validated by available drilling data, and Forrestania reports it is excited about plans to drill test the area.

Following the positive results at Giant Pegmatite, Forrestania will undertake an XRD and SEM analysis to determine the host minerals of the ‘high-grade’ lithium and tantalum intervals, and finalise drill planning to infill untested areas. The company reports all approvals have been granted for preliminary planned follow-up drilling.

Commenting on the results, Forrestania Resources Managing Director Michael Anderson said: “These latest positive results confirm the potential for significant new discoveries at our Forrestania project. It is always exciting to drill high-grade intersections and we are confident there is potential for more at Giant, and indeed elsewhere, as we continue to systematically test our high-priority anomalies and targets.

We certainly have plenty more to do to ensure that we do justice to the demonstrable prospectivity at Forrestania, and it is obvious to me after only a few weeks in the role that our team is well equipped to do that. We look forward to keeping shareholders informed as work progresses.”

At the South Iron Cap East deposit, Forrestania reports 9 holes were completed, targeting a geochemical tantalum anomaly surrounding a mapped pegmatite outcrop which occurs within 1km of IGO’s (ASX:IGO) South Ironcap lithium occurrence.

Drillhole FSIR0009 intersected 1m @ 0.10% Li2O from 59m, 4m @ 0.14% Li2O from 64m, and 1m @ 305ppm Ta from 85m. All reported intervals also returned potassium and rubidium ratios less than 30 which demonstrates that the pegmatite is part of a highly fertile system.

The company reports planning is currently underway for a follow-up drilling program to target the southwest corner of the prospect, closer to the outcropping pegmatite and where possible extensions of the intercepted pegmatite splays are interpreted to occur.

Forrestania also reports anomalous lithium and favourable geochemistry results were returned from several logged pegmatites at Gemcutter, which further confirms the known fertility of the area for lithium-caesium-tantalum (LCT) pegmatites and lithium mineralisation.

Results returned here include FGER0006 with 4m @ 0.12% Li2O from 41m and 2m @ 302ppm Ta from 42m; FGER0007 with 2m @ 0.2% Li2O from 42m and 1m @ 0.1% Li2O from 59m; as well as FGER0010 with 2m @ 0.16% Li2O from 88m.

The company says it is continuing to follow-up on the previous drilling program where multiple pegmatites were intercepted but returned no significant lithium mineralisation.

Forrestania Resources is an exploration company searching for lithium, gold, and nickel in the Forrestania, Southern Cross, and Leonora regions of Western Australia. The Forrestania Project covers a tenement footprint of about 100km, which is considered prospective for all the aforementioned elements.
