ASX ANNOUNCEMENT

21 JUNE 2012

DRILLING CONFIRMS PRESENCE OF HIGH GRADE (8‐30% P2O5) PHOSPHATE MINERALISATION

Gulf Industrials Limited (Gulf) (ASX: GLF) is pleased to report the results of its soil sampling and six hole drill program between the Busumbu prospect and the Namekara Vermiculite mine in eastern Uganda.

The phosphate target is hosted in alkaline rocks such as carbonatite within the Bukusu complex, one of Africa’s largest reported alkaline / carbonatite complexes.

The drilling results confirm the presence of high grade (ca.20‐30% P2O5) phosphate mineralisation in weathered carbonatite, which may have DSO (direct shipping ore) potential (refer to table 1 for drilling results). Lower grade mineralisation (8‐13% P2O5) may have potential for beneficiation or for direct agricultural application.

  • 510 soil samples collected along approximately 4km strike length.

  • Soil sample analyses indicate up to 3km strike extent of phosphate mineralisation is likely between Busumbu and Namekara.

  • Substantial phosphate mineralised footprint for future exploration.

  • Six diamond core holes completed for 301m total.

  • 8.23‐29.2% P2O5 in drill hole carbonatite samples to 60m down‐hole, at Busumbu and Namekara.

  • XRD analyses of the crystalline mineral phases indicates that apatite is the predominant phosphate mineral, with lesser quantities of carbonate‐fluorapatite and minor crandallite noted.

Background

Gulf operates the high‐grade Namekara vermiculite mine in south eastern Uganda, in the south‐western part of the Bukusu Complex which is one of Africa’s largest alkaline carbonatite complexes. Gulf previously identified historical information relating to a phosphate mine operated intermittently on Busumbu ridge, about 3km east of Namekara, during the period 1944 to 1963. Research at the Busumbu phosphate deposit by Edwards (1995) described the formation of calcium‐aluminium phosphates such as crandallite in the regolith to form “soft phosphate rock” and re‐precipitation of apatite to form “hard phosphate rock”.

Gulf’s 2011/2012 soil sampling and core drilling at the Busumbu – Namekara target was aimed at confirming previous the reports of phosphate mineralisation, to evaluate mineralogy and identify potential for extensions at depth and along strike.

Geology

According to previous mapping by Baldock (1967) the Bukusu Complex is composed of alkaline and ultrabasic rocks forming ring dyke structures surrounding a central vent agglomerate. Radial faulting from the centre outwards is present, though very limited outcrops have restricted the amount of detailed mapping that can be carried out. In general, the Bukusu Complex is surrounded by a broad zone of feldspathisation or fenites in which leucocratic granite, syenite and quartz‐pegmatoid have been developed from alteration of the country rocks (granodiorite‐gneisses).

Baldock also refers to “sheets and screens” of phoscorite intercalated with carbonatite in a borehole at the Busumbu phosphate prospect. The phoscorite is quoted as consisting of olivine (34.1%), magnetite (23.6%), apatite (22.1%) and biotite (13.5%) and to contain trace amounts of zircon and baddeleyite.

The Bukusu Complex also has potential to host several other mineral commodities including Calcium Carbonate, Magnetite and possibly Rare Earth Elements (REE).

Current Exploration Programme

Soil sampling was conducted to delineate the potential mineralised target, followed by diamond core drilling to test for depth extents, determine tenor of phosphate mineralisation and to identify phosphate minerals present. Soil sample results summarised in Table 2 and in Figure 2 confirm the possible extension of phosphate mineralisation between Busumbu and Namekara.

The present drilling indicates that the phosphate mineralisation north of Namekara is hosted within a steeply dipping carbonatite ring dyke that is likely to be the westward extension of similar carbonatite‐ hosted mineralisation at the Busumbu prospect. Low grade phosphate values were intersected in the ferricrete profile in borehole ND13 between 3 and 16.5m depth (Table 4). Higher grade phosphate values in the range 8.23% to 29.2% were intersected in weathered carbonatite below the soil / ferricrete horizon (Tables 1 and 4).

XRD analysis of 12 selected samples indicates that the main crystalline phosphate mineral is apatite, with lesser amounts of crandallite and carbonate‐fluorapatite (Table 3). Other crystalline minerals identified include magnetite, hematite, goethite. Poorly crystalline or amorphous material is suggested in some samples (e.g. E0588 & E0643), where the XRD patterns have high background and broad peaks.

Note: The boreholes are drilled obliquely across what is interpreted to be steeply dipping mineralisation, therefore the intervals do not represent true width, which is less than sampled width. Composite P2O5 values were derived using Micromine®2011 software. Samples were analysed during June 2012 by Genalysis Perth, using Li borate fusion XRF according to their “Phosphate Majors XRF Package” and during March 2012 according to their “REE FP6/MS package”.
