New Exploration Project Acquisition Capturing Belt Scale opportunities for mafic hosted nickel, copper, and PGE's

Duketon Mining Ltd (ASX: DKM, "Duketon" or "the Company") is pleased to announce it has been granted a large exploration licence north of the Duketon Greenstone Belt that offers belt-scale exploration opportunities for nickel, copper, and PGE's in addition to the Duketon Project that hosts the Rosie and C2 deposits.

Stuart Fogarty, Duketon Mining Managing Director said; "This new project is a valuable addition to the company's nickel exploration portfolio. The fact that BHP has drilled the one hole into the northern most intrusion is intriguing whilst the assays from that hole are weakly anomalous, they are absolutely enticing. I look forward to the results as we progress this project"

Duketon Mining Ltd (ASX: DKM, "Duketon" or "the Company") is pleased to announce it has been granted a large exploration licence north of the Duketon Greenstone Belt that is prospective for intrusion related nickel, copper, and PGE's (the "Tate Project"). The tenement offers belt-scale exploration opportunities in addition to the Duketon Project that hosts the Rosie and C2 deposits.

The tenement represents a strategic position covering the interpreted Hootanui Fault that is the boundary between two major geological terranes - the Kurnalpi and Burtville Terranes. It is a low-cost entry, prospective for mafic related nickel, copper, PGE deposits.

The tenement covers 213 km2 and encompasses the area between DKMs northern-most tenement and Cannon Resources (ASX:CNR) Fisher East Project southern-most tenement.

Two large, mafic intrusions have been identified in the data package. One is approximately 6km by 1.2km and the other is 2.2km by 1.2km.

A data review has shown there is a single historical BHP drill hole (1994) into the northern most intrusive drilled to 25 metres depth. This was logged as mafic rocks from 8m and the end of hole assay was reported to include 143 ppm nickel, 108 ppm copper, 86 ppm zinc, 2,710 ppm manganese and 9.9% iron. This is the only hole identified as intersecting either intrusion.

More recently (2013), a regional auger geochemical program has been completed covering this area along the interpretated position of the Hootanui Fault. No significant base metal anomalies were detected but previous drilling has shown a significant thickness of transported material possibly rendering the geochemical program ineffective.

This Project represents an early-mover opportunity leveraging off an alternative geological model for the area.
