VTEM Survey Underway at Merléac to Identify New Deposits

ASX Announcement - 6 July 2015

VTEM SURVEY UNDERWAY AT MERLÉAC

TO IDENTIFY NEW DEPOSITS

Commencement of Versatile Time Domain Electromagnetic survey (VTEM) to identify new volcanogenic massive sulphide (VMS) deposits within the

Merléac exploration licence.

VTEM survey will test the southern section of the licence over the high grade

Porte-aux-Moines VMS deposit and the highly prospective host rock sequences along strike.

Previous work by Variscan has identified good exploration potential at

Porte-aux-Moines and defined a number of outcropping gossans that may represent other VMS centres elsewhere within the survey area.

Gossans contain highly anomalous levels of zinc, lead, copper and gold.

Survey will help provide target outlines of VMS sulphide zones to be followed up by further exploration including drilling.

Variscan Mines Limited (ASX: VAR) is pleased to announce that its wholly owned European subsidiary Variscan Mines SAS has commenced a large heli-borne VTEM survey over the southern section of its Merléac exploration licence in Brittany, France.
The VTEM survey has been designed to test the key target areas in and around the high grade zinc-lead-copper-silver-gold Porte-aux-Moines VMS deposit that has been the focus of recent Variscan work.
The survey will cover approximately 50 strike kilometres of prospective volcanics and sediments known to host VMS mineralisation and will provide an initial geophysical test for the presence and geometry of sulphide zones below both known outcropping gossans and those concealed under shallow cover.
The survey is expected to be completed within two weeks with final models available in early
August.
The survey will be the first of its type flown in France for mineral deposits and will introduce state- of-art technology into the Variscan exploration programme.

Previous work

Recent work by Variscan within the Merléac exploration licence has focussed on the high grade Porte-aux-Moines zinc-lead-copper-silver-gold VMS deposit where resampling of available old BRGM (Bureau de Recherches Géologiques et Minières - the French geological survey) core in hole PAM5 recorded a number of high grade, zinc-dominant, polymetallic intersections such as 31 metres @ 10.4% zinc, 2.1% lead, 1.2% copper, 105.5 g/t silver, 1.0 g/t gold from 236 metres (including 8 meters @ 25.0% zinc, 5.4% lead 1.6% copper, 208.5 g/t silver, 1.39 g/t gold from

236 metres) (see ASX announcement 19 May 2015).

Porte-aux-Moines exhibits many of the classic geological features found in other VMS deposits, in particular the possibility for a cluster of sulphide lenses within the project area. Logging of the BRGM holes has recorded multiple intersections of polymetallic mineralisation indicating perhaps three mineralising events over a 50 meter interval within the mine sequence. This suggests the scope for the discovery of a stacked massive sulphide system and provides encouragement that Porte-aux- Moines could be significantly larger than currently defined.
In addition, the regional potential within the Merléac licence for additional VMS deposits is considered excellent. Porte-aux-Moines is hosted within a sequence of vitric tuffs and pyritic black shales (the mine sequence) located in a bimodal sequence of felsic and intermediate/mafic volcanics. This sequence of rocks can be traced for approximately 70 kilometres along strike and within structurally(?) repeated blocks in the Merléac licence.
Within these rock units Variscan has defined outcropping gossans containing highly anomalous base and precious metal values interpreted to represent the oxidised expressions of underlying massive sulphides/stockwork zones (see ASX announcements from 8 December 2014 and 5
February 2015). Some of these gossans were previously mined by shallow open pits for iron up until the 19th century and generally have not been explored below the iron oxide cap aside from shallow BRGM drilling in some locations. They represent immediate exploration targets.

VTEM Programme

To help target potential VMS mineralisation in and around Porte-aux-Moines and the region a large heli-borne electromagnetic (VTEM) survey has commenced. The survey will cover up to approximately 180 square kilometres of the southern prospective section of the Merléac licence (Figure 1). The VTEM will test approximately 50 strike kilometres of the VMS host stratigraphy for the presence and geometry of sulphide zones below both known outcropping gossans (including Porte-aux-Moines) and those concealed under shallow cover.
VTEM is widely considered one of the best helicopter-borne TEM geophysical systems for detecting and imaging massive sulphide deposits in the industry. Notable recent successes in Australia include the discovery of the Mallee Bull deposit in the Cobar Basin (see reports by Peel Mining, ASX: PEX), and the recent Artemis discovery in Queensland by Minotaur Exploration (ASX: MEP). The VTEM system is flown using a helicopter that tows a powerful electromagnetic transmitter and receiver which can detect massive sulphide mineralisation to considerable depths below the surface.
The base and precious metal VMS deposits of the Merléac region such as Porte-aux-Moines are pyrite rich and considered likely generate conductive responses to electromagnetic input as
delivered by the VTEM system. Data produced from the survey will be modelled by Resource
Page | 2 ASX Announcement - 6 July 2015

Potentials Pty Ltd from Perth to generate plate simulations of the interpreted geometry of any sulphide zones detected which may then be followed up with detailed surface EM and/or drilling.
It is expected that the VTEM survey will be completed within the next two weeks, with final modelling and exploration target generation within the following month.

parties

Last significant exploration in area is believed to have been conducted by BRGM in the 1980s.

VMS potential of the region was recognised by the BRGM who conducted regional stream sediment programmes during the mid-1970s. The Porte-aux-Moines deposit was discovered in

1975 when follow-up soil sampling and shallow drilling intersected massive sulphides.

Subsequently the BRGM conducted substantial core drilling (+9km) and underground development on Porte-aux-Moines.

In addition, the BRGM conducted significant mapping, geochemical and geophysical programmes around Porte-aux-Moines and regionally.
