Dalgaranga Project

Krakatoa Resources Ltd holds 100% interest in the Dalgaranga Tantalum-Niobium Lithium Project, located 80km north west of Mount Magnet in Western Australia.

Historical infrastructure including significant access tracks, tailings dam, water monitoring bores and ore stock piles (with remnant oversize material).


Project Geology
The geology of the Dalgaranga Project consists of a suite of fine grained, foliated, clastic sediments (siltstone and arkose) with tuffaceous units occurring on the eastern margin.

Tuffaceous units within the open pit include bands (<300mm) of chiastolite rich siltstone (“knotted schists”). The rocks are folded with north easterly axes and are often moderately foliated. Banded iron formations exist on the north west margin.

The “Open Pit Pegmatite Vein” and those veins to the south appear to have been intruded parallel to the folded sediments. Within the open pit area pegmatites range between 0.5 to >10m in thickness. To the south of the ROM and tailings dam, pegmatites ranging between 0.5 to 3m thickness have been mapped.


The main tantalum minerals at Dalgaranga Mine were tapiolite and tantalite, with lesser microlite. Tantalite ranged from very fine grained to very coarse, up to several centimeters. Local concentrations of tin, tungsten and lithium minerals have also been noted.

Occurrences of Zinnwaldite (lithium mineral, KFe22+Al(Al2Si2O10)(OH)2 to KLi2Al(Si4O10)(F,OH)2) have been noted by the Western Australian Museum. Detailed mapping and sampling is to be undertaken to determine the potential and extent of lithium mineralisation within the Project.


Rock Chip Sampling

A rock chip sampling campaign was conducted within the vicinity of the historical Dalgaranga Open Pit. The program aimed to determine the tenor of exposed mineralisation within the open pit, confirm the presence of Zinnwaldite (lithium mica mineral) and develop an understanding of the potential for hosting extensions to the previously mined tantalum-niobium mineralisation.


Rock chip samples returned up to 1,854ppm Ta2O5 confirming that high grade mineralisation remains within the open pit. Detailed mapping and channel sampling is proposed to be conducted to determine the extents of mineralisation within the surrounds of the open pit.




Mac Well Project

The Mac Well Project has a land area of 66.9km2, covers the pegmatite occurrence, and is located 10km west of Krakatoa’s Dalgaranga Project.

The Mac Well Project area contains outcrops of metamorphosed basic rocks enclosed by granitic migmatite. South of the project area, the migmatites become more porphyritic.Banding in the migmatite mimics the granite contact with basic rocks and swings from northeast to northwest.
