Marketwired Canada
Reunion Gold Corporation (TSX VENTURE:RGD) ("Reunion or the "Company") is
pleased to provide an update on its exploration activities at the Matthews Ridge
manganese project in Guyana, South America.
The Company has concluded its planned exploration program for 2012, completing a
total of 47,570 meters of diamond drilling in 735 holes, 17,361 meters of
reverse circulation drilling in 283 holes, 217 meters of Banka drilling in 119
holes and 365 sampling pits. Reunion has received complete assay results from
all drill holes and all results received since the Company's October 31, 2012
press release are reported in this press release.
Highlights of the most significant new diamond drill assay results are presented
in Table 1. Refer to Appendix 1 for complete new results.

Drilling results continue to indicate an excellent correlation with trench
intersections, confirming that mineralization persists regularly throughout the
saprolite zone and continues as proto-ore in the fresh rock. Maps showing the
target hills and location of mineralized zones in relation to the drill holes
are provided in Appendixes 2 and 3. Diamond and RC drilling has been done to the
saprolite-fresh rock interface. The Company intends to define resources in the
saprolitic, detrital and tailings materials, which are amenable to simple
earth-moving extraction.
The metallurgical testing of the various ore materials is now complete. The test
results will be reported when the final report becomes available.
An independent "Qualified Person" (as defined under Canadian National Instrument
43-101 ("NI 43-101")) is currently doing the geological modeling of manganese
mineralization for target Hills 1 to 9, with the objective of completing an
initial resource estimate compliant with NI 43-101.
Banka drilling of tailings material
The previous mining of manganese ore at Matthews Ridge in the 1960's have
produced a significant volume of tailings material, which did not meet
commercial specifications at the time, but that was conveniently deposited next
to the processing plant in a shallow valley. The Company completed the sampling
of this material by doing 119 holes using a manual Banka drill with six-inch
casing. This work confirmed that the tailings cover has an average thickness of
0.86 m and the average grade of 208 samples assayed 15.62% Mn.
Pitting of detrital material
The so-called detrital material consists of deposits formed by manganese nodules
and fragments derived from the erosion of lateritic duricrust and saprolitic
material, forming "blankets" overlying the target hills. Reunion sampled this
material with 365 mechanized and manual pits and the results are compiled in the
table below:

Exploration of eastern extension
Reunion has started the systematic trenching of its 5 km-long eastern extension
discovery, as reported previously and referred to as "Arakaka". This program
aims to define the extent and characteristics of manganese mineralization to the
east of Hill 1, with the objectives of including mineralized material from this
area in the global footprint resources.
Project description
The Matthews Ridge Project consists of four Prospecting Licenses covering an
area of 185 km2 located in northwest Guyana, in and around the former Matthews
Ridge mine. The Company also holds two Permissions for Geological and
Geophysical Surveys ("PGGS") for manganese over an area of 14,970 km2
surrounding the four Prospecting Licences. Manganese ore was mined from 1960 to
1968 by Union Carbide and exported via railroad and a fluvial port. Mining was
done on five of a series of nine hills extending for 15 km and striking
northeastern-southwestern (see Appendix 2).
Manganese mineralization is hosted by the Barama Group sedimentary sequence of
Proterozoic age and consists of typical saprolitic and detrital deposits formed
as a result of supergene enrichment of manganese-rich sediments under a tropical
climate. The saprolitic deposits are formed by manganese oxide and hydroxide
minerals occurring along the crest of hills and are related to the weathered
lateritic profile, reaching 100 m below surface.
Quality assurance and quality control
Diamond drilling was done using HQ-diameter casing and triple-tube core barrel
to maximize recovery. Half of the core was used for sampling at regular 1.5 m
intervals. Reverse circulation drilling was done with four-inch casing, sampling
at every meter and splitting the rock chips once in the field and processing an
entire half sample. Banka drilling of tailings was done with six-inch casing and
sampling at every meter. Sampling of detrital material is being done by 30
cm-wide vertical channels in pits. Standard reference materials, internal
standards, blanks and duplicate samples have been used to control laboratory
accuracy and precision. Core sample preparation was done by Activation
Laboratories Ltd. and ACME Laboratories at their facilities in Georgetown,
comprised of crushing to minus 2 mm and pulverization passing 200 mesh, followed
by XRF assays for manganese and other relevant oxides at their laboratories in
Canada. Sample preparation and XRF assay of reverse circulation drill, Banka
drill and pit samples were done by FILAB Guyana Laboratories on site using the
same methodology described above. Samples of saprolitic, detrital and tailings
material are also being processed by a scrubbing / jigging pilot plant operated
by FILAB under the supervision of GMining Services, as part of the metallurgical
testing of mineralized materials.
Carlos H. Bertoni, P. Geo., a qualified person as defined under the terms of NI
43-101, has verified the data and approved the technical information contained
in this press release.
