• High grade tungsten hits of up to 1.9% WO3, mineralisation open in most directions.
• Bulk tonnage low grade tin-tungsten sheeted vein targets
• Ironbark has commenced discussions regarding the Burrandana project with other parties.

The project area was explored and drilled by Shell in the late 1970’s and early 1980’s targeting tin-tungsten (Sn-W) mineralisation. Three key prospects have been identified (Tin Hill, Tungsten Valley and Pachmarhi) through mapping, soil sampling, trenching, Rotary Air Blast (RAB), Reverse Circulation (RC) and Diamond (DDH) Drilling.

The geology of the prospect area is shown in Figure 3 and comprises metamorphosed Ordovician sedimentary rocks, biotite-rich and tourmaline-rich altered granites. Mineralisation is characterised by sheeted quartz-vein sets hosting scheelite and cassiterite mineralisation.

Significant drill intercepts from the limited drilling conducted at the Tin Hill prospect to date include;-

• 1.5m @ 1.9% WO3 from 26m (PBT14),
• 4.0m @ 1.2% WO3 from 36m (PBT04),
• 6.0m @ 0.18% Cu and 0.6% WO3 from 18m including 2m @ 0.26% Cu and 1.6% WO3 (PBT05).

The mineralisation at Tin Hill is interpreted to be a flat lying greissen system and remains open in almost every direction.

In the northern part of the licence at the Pachmarhi prospect one deep diamond drill hole (DCP1) targeting a down dip position of outcropping anomalous tin-tungsten sheeted veins intersected ore-grade W mineralisation (0.9m @ 0.87% WO3) from 161.1 metres down hole.

Ironbark is targeting bulk tonnage sheeted-vein tin-tungsten mineralisation and has commenced discussions with other parties to further advance this project.
