High Grade Zinc Results at Porte-Aux-Moines
ASX Announcement – 14 December 2015
HIGH GRADE ZINC RESULTS AT PORTE-AUX-MOINES
Digital conversion of data from previous BRGM exploration and mine
development work at Porte-aux-Moines deposit progressed as part of JORC
Resource estimation work.
Assay results received for 56 of the 58 holes drilled into the deposit.
Numerous high grade results were recorded including 27.0 metres @ 14.0% zinc, 3.3% lead, 0.8% copper, 161.4 g/t silver,
0.8 g/t gold from 143.5 metres (26.0% Zn Eq) in PAM14
12.5 metres @ 11.3% zinc, 2.7% lead, 2.5% copper, 157 g/t silver
from 49 metres (24.2% Zn Eq) in SF08
19.0 metres @ 9.5% zinc, 1.7% lead, 1.2% copper, 103.3 g/t silver
from 15 metres (17.6% Zn Eq) in SF12
8.5 metres @ 14.5% zinc, 3.4% lead, 1.6% copper, 144.2 g/t silver
from 99.5 metres (27.2% Zn Eq) in SF27
Interpreted mineralised envelope defined over a strike length in excess of
300 metres.
Potential economic significance of the deposit continues to be confirmed.
Assays will contribute to the calculation of a 2012 JORC compliant
Resource, planned for completion Q1 2016.
Variscan Mines Limited (ASX: VAR) is pleased to announce its wholly owned subsidiary Variscan
Mines SAS has made good progress in converting historic exploration data from the Porte-auxMoines volcanogenic massive sulphide (VMS) deposit within the Merléac exploration licence,
Brittany, France to electronic formats as part of JORC Resource estimation work.
The work has identified numerous of high grade zinc-lead-copper-silver intervals within massive
sulphide horizons confirming the overall high grade nature of the deposit.
The work provides strong evidence that a robust JORC compliant Resource estimate can be
generated for the deposit once additional geological and check work is completed.

BRGM and Recent work
Former exploration by the BRGM (Bureau de Recherches Géologiques et Minières - the French
geological survey) at the Porte-aux-Moines VMS deposit has been extensive and of high quality. The
BRGM conducted a major exploration programme at the deposit from 1976-1984 including
approximately ten kilometres of surface and underground drilling and two kilometres of underground
mine development. This work defined zones of high grade zinc-lead-copper-silver-gold mineralization
up to 20 metres thick from near surface to a depth of about 300 metres within a stacked massive
sulphide system.
Recently, Variscan Mines sampled the three remaining preserved surface core holes drilled into
Porte-aux-Moines announcing a number of outstanding, high grade, zinc-dominant, polymetallic
intersections (see ASX announcements dated 19 May, 20 and 29 July 2015).
In November the Company received a comprehensive two gigabyte dataset from the BRGM
containing scanned copies of all available technical information generated by the BRGM exploration
work at Porte-aux-Moines including drill hole logs, assays, mine development, mapping data and
metallurgical work.
Variscan staff have commenced converting this data to electronic formats to allow 3D modelling of the
deposit and the generation of a 2012 JORC Resource estimate. Progress has been good with survey
and assay data for the majority of surface and underground drill holes now captured and modelled
into Surpac. Of the 58 holes drilled into Porte-aux-Moines by the BRGM, zinc-lead-copper-(+- silver)
assays have been received for 56, with a small proportion of holes also analysed for gold.
In summary, the recent work by Variscan has 1. Confirmed the overall high grade nature of the deposit. A significant number of intersections at
>15 % zinc equivalence have been recorded both in surface and underground holes (Table B)
with individual assay intervals up to 50.3% zinc equivalence (for notes on Zn Eq calculation go
to bottom of Table B).
These include
27.0 metres @ 14.0% zinc, 3.3% lead, 0.8% copper, 161.4 g/t silver, 0.8 g/t gold from
143.5 metres (26.0% Zn Eq) in PAM14.
12.5 metres @ 11.3% zinc, 2.7% lead, 2.5% copper, 157 g/t silver from 49 metres
(24.2% Zn Eq) in SF08.
19.0 metres @ 9.5% zinc, 1.7% lead, 1.2% copper, 103.3 g/t silver from 15 metres
(17.6% Zn Eq) in SF12.
8.5 metres @ 14.5% zinc, 3.4% lead, 1.6% copper, 144.2 g/t silver from 99.5 metres
(27.2% Zn Eq)in SF27.
2. Indicated mineralisation extends over a strike length of more than 300 metres, with a recent
VTEM survey by Variscan suggesting possible extensions outside the drilled area to the west
(ASX announcement dated 28 September 2015).
3. Confirmed a zone of thick, high grade mineralisation from around -150 metres to -250 meters
below the surface (Figure 1).

4. Highlighted the good data density (drill hole intercepts and underground cross-cuts) within the
main mineralised envelope, enhancing the likely reliability of geological interpretations and
resource models.
Importantly, Variscan's recent resampling of core holes PAM5, 8 and 16 has confirmed the good
quality of previous BRGM base and precious metal assaying, detecting little variation between results
from the BRGM and ALS Geochemistry. This provides high confidence in the veracity and accuracy of
the remaining BRGM drill hole and mine development assays to allow calculation of a Resource to
2012 JORC standards. This work has commenced and is expected to be completed in Q1 2016.
Figure 1 - Cross section through the Porte-aux-Moines deposit highlighting the high grade BRGM assays in PAM14. The
gold values in PAM14 are incomplete and likely to be lower than the actual gold grades. Assays from PAM16 (light grey
background) are from ALS Geochemistry and were reported 20 July 2015. The geological interpretation comes from
BRGM reports.

Notes
Holes with PAM prefix are surface core and SF prefix underground core.
Holes PAM5, PAM8 and PAM16 have complete gold assays per interval (from ALS). All other holes have not been
assayed for gold or have incomplete gold assays.
The Zinc Equivalent is based on zinc (US$1,800 per tonne), lead (US$1,800 per tonne), copper (US$5,600 per
tonne), silver (US$15 per ounce) and gold (US$1,150 per ounce). The zinc equivalent calculation represents the
total metal value for each metal, multiplied by a price based conversion factor, summed and expressed in
equivalent zinc percent per tonne. These results are exploration results only and no allowance is made for
recovery losses that may occur should mining eventually result. Nevertheless, it is the Company's opinion that all
the elements included in the metal equivalents calculation have good poten tial to be recovered as is commonly the
case for similar VMS deposits worldwide. The zinc equivalent calculation is intended as an indicative value only.

Original samples (1976-1984) were taken from sawn quarter core by the BRGM (Bureau de
Recherches Géologiques et Minières - the French geological survey).
Recent samples for PAM5, 8 and 16 were taken from remaining quarter core.
The mineralised core size is NQ .
BRGM sampling was taken at between 0.5 to 2 metre intervals.
Quarter core samples for PAM5, 8 and 16 were bagged and sample prepped by the BRGM and
assayed by ALS Geochemistry
Quarter core samples for all other holes were bagged, sample prepped and assayed by the
BRGM.
All surface and underground holes were diamond core.
Surface drill holes were collared and drilled with “PQ” diameter core before switching over to
“HQ” diameter core to generally around 200 m and then to thin wall “NQ” core for the balance
of the hole.
Core was not oriented.
The drill core was stored in wooden trays and was logged for core recoveries. Most mineralised
intercepts recorded >95% recoveries, but this was variable dependent on ground conditions.
Holes PAM5,8 and 16 were re-logged by Variscan geologists and entered into an electronic
database
All other holes were logged by BRGM geologists onto paper log sheets
Details, including survey information, geological logs (converted to Variscan legend), assay data
and recoveries are now being entered into an electronic database by Variscan geologists
For hole PAM5, 8 and 16 –
Samples were collected by BRGM personnel, bagged and tagged with unique sample numbers.
Sample numbers were entered against down-hole depths and sent to Variscan geologists
Average weight per sample was around 2kg
Samples were prepared by the BRGM
Samples were dried and crushed to -2 mm
Samples were then split down with riffle box to recover 100 g
The sample splits were pulverized in a hammer mill to -80 µm
Samples were transported to ALS Geochemistry Ireland for analysis
For all other holes –
Samples were collected, bagged and sent for sample prep and analysis at the BRGM laboratories
from 1976 to 1984 by BRGM personnel.
For hole PAM5, 8 and 16 The ALS assay method used for base metals was ME-ICPORE (multi element analysis of base
metal ores and mill products by atomic emission spectrometry using inductively coupled plasma
spectrometer) which uses a highly oxidizing attack designed for high grade sulphides (the sample
is dissolved with HNO3 , KClO4 and HBr and the final solution in dilute aqua regia).
Gold was analysed using a 30 g fire assay and AA finish (AA23). When high grade gold results
were recorded, additional gold assays were completed with fire assay and a gravimetric finish.
(Au-GRA21)
10% of samples were analysed as duplicates for QA/QC control.
Variscan data storage in Excel spreadsheets and GIS database.
For PAM5, PAM8 and PAM16, logging and assay checks against visible sulphide mineralisation
completed by Variscan geologists.
ALS assays checked against a large number of BRGM assays (1970/80’s) from identical sample
intervals. Overall repeatability between the ALS and BRGM assays is considered very good for all
elements and provides strong confidence in the accuracy of all previous BRGM assays.
BRGM blanks and standards were included within the samples submitted to ALS.
Collar positions and downhole surveys were provided by the BRGM.
Projection and recording of data points into the GIS database (RGF93 projection) by Variscan.
BRGM quarter core sampling at a maximum downhole intervals of 3 metres defined by geology.
Variscan core resampling in holes PAM5, 8 and 16 used 1 to 2 metre sample compositing for
comparison work against the original BRGM samples.
The majority of core holes were drilled at reasonably high angles to the interpreted sub-vertical
to very steeply north dipping mineralisation.

Commentary
structure
Sample security
Audits or reviews
In holes PAM5, 8 and 16 the core angles of sulphide and host rock bedding were consistently
high to the core axis throughout the holes providing a reasonable test through the mineralised
zones.
Samples for PAM5, 8, 16 were prepared at the BRGM prep facilities and transported to ALS
Geochemistry Ireland by commercial carrier.
Sample prep for all other holes (1976-84) was completed at BRGM lab facilities in France.
There has been no external audit or review of the Company’s techniques or data.

No known impediments for future exploration and development
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
1976 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.
Much of the exploration data is held by the BRGM and will be compiled and assessed by the
Company.
Volcanogenic Massive Sulphide (VMS) deposits
Three full core holes (PAM5, PAM8, PAM16) have been accessed and logged by Variscan
geologists at the BRGM core facility, Orleans.
Original BRGM logs, coordinate/downhole data and assays is being complied by Variscan
geologists.
No aggregation or high grade cuts have been applied to the data reported
The orientation of the holes is considered a reasonable test of the high grade mineralised zones
which appear to dip from sub vertical to very steeply north.
Based on the BRGM interpretation of the mineralised envelops and the core angles of sulphide
layering as recorded by Variscan geologists in PAM5, 8 and 16, the average true widths of the
intersections are estimated to be around 40-90 % of the downhole lengths. This will be
confirmed once wireframes of interpreted mineralised envelopes are generated by Variscan
geologists for use in a 2012 JORC resource estimate.
Diagrams for the Porte-aux-Moines deposit have been taken from published BRGM reports.
All intersections of mineralisation above a 4% Zn Eq cut-off are published within the report
Previous exploration, mining, metallurgical and hydrological data was received by the Company in
November 2015 and will be reported by the Company as it is accessed, complied and evaluated.
