EXPLORATION UPDATE ‐ MT ALEXANDER PROJECT

HIGHLIGHTS:

• Drilling of electromagnetic (EM) conductors identified by St George scheduled to commence mid‐April 2016

• Surface EM surveys over new target areas identified by St George will commence next week

• Technical review of the nickel sulphide prospectivity of the Mt Alexander greenstone belt and 3D geological modelling of Cathedrals in progress

• Pipeline of high quality massive nickel‐copper sulphide targets with strong potential for further discoveries at Mt Alexander

EXPLORATION PROGRESSES AT MT ALEXANDER

St George Mining Limited (ASX: SGQ ) (‘St George’ or ‘the Company’) is pleased to provide an update on exploration for massive nickel‐copper sulphide mineralisation at the Mt Alexander Project in Western Australia.

A diamond drill programme has been planned for Mt Alexander and is scheduled to commence in mid‐April 2016. Drilling will target untested EM conductors at the Cathedrals and Stricklands Prospects that coincide with magnetic anomalies.

BHP Billiton Nickel West (“Nickel West”) drilled three EM conductors at Cathedrals in 2008 and all three were confirmed as high grade nickel‐copper sulphide mineralisation. The untested EM conductors to be drilled by St George next month have similar geophysical responses to the massive nickel‐copper sulphide EM conductors drilled in 2008, and are also located within the Cathedrals shear zone.

A Programme of Works has been approved by the Department of Mines and Petroleum, and DDH1 Drilling Pty Ltd has been retained to carry out the drilling. Further details of the drill programme will be announced closer to the commencement of drilling. Our review of project data is ongoing and the drill programme may be expanded to test additional targets.

St George Mining Executive Chairman, John Prineas said:

“The testing of EM conductors at Cathedrals has a 100% success rate to date. This makes the untested EM conductors at Cathedrals, and along strike at Stricklands, high conviction targets for the discovery of more massive nickel‐copper sulphides.

“The upcoming drill programme will also test the continuity of the high grade mineralisation already discovered at Cathedrals.

“A surface EM programme, which will test magnetic anomalies west of Stricklands and to the north of Cathedrals, could provide further walk‐up drill targets.

“We are looking forward to commencing the drilling and EM surveys and to reporting on important exploration milestones.”

PIPELINE OF TARGETS AT MT ALEXANDER

A moving loop electromagnetic (MLEM) survey will be completed over two highly prospective areas at the Mt Alexander Project, with the surveys scheduled to commence on 28 March 2016. These areas are illustrated in Figure 1 as the “Investigators” target and the “New Target Area”.

The Investigators target is located in the western section of the Cathedrals Shear Zone and directly along strike from the Cathedrals discovery. This area has no EM coverage or drill testing. The MLEM survey will test for bedrock conductors in this area.

In the New Target Area, five anomalous EM responses were identified from a fixed loop EM survey completed by Nickel West in 2014. Modelling of these EM anomalies indicates they are bedrock conductors with similar conductivities to the massive nickel‐copper sulphides discovered at Cathedrals. A further MLEM survey will be completed over these EM anomalies to better define the conductive sources ahead of drill testing.

Untested EM conductors have been identified at Cathedrals and Stricklands, and will be drilled in the upcoming drill programme. EM surveys will be completed at Investigators and the New Target Area, with potential to generate additional EM targets for drilling.

Completion of the MLEM surveys is expected to take approximately 15 days. Drilling of the untested EM conductors is planned to commence after the surveys are completed. For further details on these EM conductors see our ASX Release dated 17 February 2016 ‘Massive Nickel‐Copper Sulphide Targets at Mt Alexander’ .

In conjunction with the upcoming exploration programmes, further work is also being conducted using the existing data for the Mt Alexander Project. A technical review of the nickel sulphide prospectivity of the Mt Alexander greenstone belt, including re‐logging of the historic drill core, is almost complete.

3D geological modelling of Cathedrals and re‐logging of drill core is also in progress. The results of the 3D modelling are being used to assist with drill planning, and also to identify any continuity of massive and disseminated nickel‐copper sulphide mineralisation in the Cathedrals ultramafics. Results from these reviews will be announced shortly.

The interval highlighted in this photo recorded 1.4m @ 7.1%Ni, 3% Cu and 4.2g/t PGEs from 57.6m. There is strong potential for further intersections of high grade mineralisation in the 2016 planned drilling at Mt Alexander.

ABOUT THE MT ALEXANDER PROJECT:

The Mt Alexander Project is located 120km south‐southwest of the Agnew‐Wiluna belt which hosts numerous world class nickel deposits. The Project comprises two granted exploration licences – E29/638 and E29/548.

The Cathedrals nickel‐copper discovery and the Stricklands Prospect are located on E29/638, which is held in joint venture by Western Areas Limited (25%) and St George (75%). St George is the Manager of the Project with Western Areas retaining a 25% non‐contributing interest in the Project (in regard to E29/638 only) until there is a decision to mine.
