ASX Release 31 July 2015

Hoist EM Conductors & Structural Targets

Identified at Gimlet

HIGHLIGHTS

• Geophysical review of Gimlet Project completed

• Fifteen targets identified, including six high priority EM conductors

• Review of historical auger and soil geochemistry underway

Terrain Minerals Ltd (ASX:TMX)("Terrain" or "the Company") is pleased to announce that a recent review of available geophysical and structural data at its Gimlet Project, within the south-west portion of the Fraser Range Province, has resulted in the identification of fifteen discreet exploration targets of which six have been deemed to be of high priority and worthy of further investigation.

The targets were derived from a review of transient electromagnetic (TEM) and aeromagnetic data combined with a new structural interpretation of the tenement. Review of aeromagnetic data in light of the structural interpretation, resulted in the identification of an additional nine targets of second and third order priority. Terrain's predecessors had evaluated the available geophysical coverages separately and for predominantly uranium and gold potential. It is through the evaluation of the multiple surveys and the differing targeting model that Terrain was able to identify these targets warranting further investigation.

Description of High Priority Targets:

The six targets have been assigned an exploration priority based upon an empirical estimate of the depth of burial of the EM conductor and a subjective assessment of its structural setting.

• HEM1 is a series of up to 3 EM conductor anomalies which appear to coalesce at depth. The conductors sit on the northern side of a large scale NW-SE trending fault structure which transects the project area and intersects the Jerdacuttup fault at a high angle some 6 km north of the lease boundary.

• HEM2 is an EM conductor anomaly located at the centre of a large ring structure. The conductor anomaly sits at the intersection of a NNE-SSW trending fault with a NW-SE trending fault which marks the southern boundary of an interpreted NW-SE trending zone of extensional sheer. The northern boundary of the interpreted zone of sheer is marked by a NW-SE trending fault upon which the HEM1 EM anomalies appear to juxtapose.

• HEM3 is an EM conductor anomaly on the eastern side of the HEM1 series conductors and sits on the eastern side of an intersection between a curvilinear fault that swings from SSW- NNE trending to NNW-SSE as it transects the large ring structure hosting the HEM2 conductor at its centre.

• HEM4 is a shallow EM conductor anomaly on the north-western side and adjacent to the margin of the ring structure hosting HEM2. The anomaly sits on the northern side of the more southerly NW-SE fault and is adjacent to the interpreted NW-SE zone of extensional shear on its western side.

• HEM5 is a shallow EM conductor anomaly situated on the western side of the project area and situated between converging N-S and NW-SE trending faults.

• HEM6 is a an EM conductor in the south of the project area located adjacent

to a NNW-SSE trending fault

Further Work:

Further work programmes to be undertaken include a review of historical geochemical data and generation of a series of staged geochemical soil survey programmes to further evaluate the potential of the EM conductors and the attendant structural features with potential to host Ni -Cu mineralisation.
