Page 2 of 1


LONGUEUIL, CANADA -- (Marketwired) -- 07/12/13 -- Reunion Gold Corporation (TSX VENTURE: RGD) ("Reunion or the "Company") is pleased to announce that it has received the mineral reserves estimate and results of the pre-feasibility study ("PFS") for its wholly-owned Matthews Ridge Manganese Project in northwest Guyana, South America (the "Project").

Highlights (all currency in US dollars):

-- Proven and probable mineral reserves of 26.3 million tonnes with an average grade of 14.2% Mn;-- Open pit mine and conventional washing and gravity plant processing 2.8 million tonnes of ore per year;-- Production of 750,000 tonnes of manganese concentrate per year over a 10 year mine life, mainly suitable in silico-manganese furnaces;-- Initial capital cost of $233 million;-- Internal rate of return of 15.7% based on consensus manganese price forecasts;-- Satellite manganese deposits offer significant potential to extend mine life or lead to expansion.

The mineral reserve estimate and PFS were prepared under the direction of GMining Services Inc. ("GMining") with inputs from other specialized consultants, in accordance with the requirements of the Canadian Institute of Mining Guidelines and Canadian National Instrument 43-101 "Standards of Disclosure for Mineral Projects" ("NI 43-101"). The PFS describes the scope, design and viability of developing the Matthews Ridge Project based on a simple open pit mining operation with gravity concentration and exporting lump and fine concentrates.

David Fennell, Executive Chairman of Reunion, stated: "The completion of the Matthews Ridge Project pre-feasibility study is an important milestone for the Company. The study indicates the viability of the Project. Matthews Ridge could become a significant manganese producer at a site close to the North American and European markets. Reunion intends, subject to available financing, to carry out the work for the completion of a full feasibility study, which will include defining manganese resources from satellite deposits, targeting a production decision in the second half of 2014".

Mineral Reserves

In February 2013, Reunion announced unconstrained measured and indicated mineral resources for the Matthews Ridge footprint area (Figure 2), totaling 32.4 million tonnes at 14.0% Mn using an 8% Mn cutoff grade (see February 21, 2013 press release and NI 43-101 Technical Report - Matthews Ridge Manganese Project dated February 20, 2013 available on SEDAR and on the Company's website). The proven and probable reserves stated below were estimated based on these unconstrained measured and indicated resources, the work carried out for the PFS and industry standard open pit optimization techniques, and demonstrate a 81% conversion rate from resources to reserves:

--------------------------------------------------------------------------------------------------------------------------------------------------------Mineral Reserve Mass GradeClassification (t) (% Mn)--------------------------------------------------------------------------------------------------------------------------------------------------------Proven 14,055,585 15.1----------------------------------------------------------------------------Probable 12,237,833 13.3--------------------------------------------------------------------------------------------------------------------------------------------------------Total proven and probable reserves 26,293,418 14.2--------------------------------------------------------------------------------------------------------------------------------------------------------Lump concentrate 4,448,631 39.1----------------------------------------------------------------------------Fine concentrate 2,763,170 36.4--------------------------------------------------------------------------------------------------------------------------------------------------------


1. The effective date for the mineral reserve estimate is July 7, 2013.2. The cutoff grade used is 8% Mn.3. For resource parameters, see the Reunion press release of February 21, 2013.4. Average waste to ore strip ratio: 1.59:1.5. The open pit shells and designs developed for estimating reserves are based on a benchmark manganese price of $5.50/dry metric tonne units ("dmtu") CIF China, recommended pit slopes, calculated operating costs and metallurgical recovery equations derived during the test program.

Production Plan

Production is scheduled over a period of 10 years. The average annual production rate is 2.8 million tonnes of ore fed to the process plant. The table below is a summary of the average life-of-mine (LOM) and total production:

--------------------------------------------------------------------------------------------------------------------------------------------------------Description Units Average LOM Total--------------------------------------------------------------------------------------------------------------------------------------------------------Ore mined 000 t 2,780 26,293----------------------------------------------------------------------------Waste mined 000 t 4,460 41,798----------------------------------------------------------------------------Total tonnes mined 000 t 7,240 68,091----------------------------------------------------------------------------Mill feed grade % Mn 14.2 14.2----------------------------------------------------------------------------Lump concentrate production 000 t 462 4,449----------------------------------------------------------------------------Lump concentrate grade % Mn 39.1 39.1----------------------------------------------------------------------------Fine concentrate production 000 t 288 2,763----------------------------------------------------------------------------Fine concentrate grade % Mn 36.4 36.4----------------------------------------------------------------------------Total concentrate production 000 t 750 7,212--------------------------------------------------------------------------------------------------------------------------------------------------------

Note: For lump and fine concentrate specifications, see Reunion's press release of February 21, 2013.

Open pit mining would be carried out by hydraulic excavators and articulated trucks with an anticipated mining recovery of 100%. The process plant flow sheet consists of scrubbing, screening and jigging to produce lump and fine concentrates. Metallurgical testing of the different ore types demonstrates very good and straightforward upgradability (see Reunion's press release of August 27, 2012, and February 21, 2013). Metallurgical recovery is anticipated at 73%. Concentrate is to be transported by road trains to a storage facility on a fluvial berth at Port Kaituma capable of loading ocean-going barges, using logistical concept already practised by the previous miners of Matthews Ridge. Current plans are to send the concentrate to a transhipment facility in Trinidad, where they would be loaded on dedicated bulk carriers.

Capital Cost

The initial capital cost required to bring the Project into production is estimated at $ 233.0 million, including a $21.7 million contingency. An additional amount of $24.9 million would be required in sustaining capital over the life of the mine. Breakdown of the initial capital cost is summarized below:

--------------------------------------------------------------------------------------------------------------------------------------------------------Description Cost (million)--------------------------------------------------------------------------------------------------------------------------------------------------------Mining Equipment 12.9----------------------------------------------------------------------------Process plant 34.1----------------------------------------------------------------------------Infrastructure on-site 68.9----------------------------------------------------------------------------Infrastructure off-site 43.1----------------------------------------------------------------------------Total direct costs 159.0----------------------------------------------------------------------------Indirect costs (engineering, construction, freight, etc.) 52.3----------------------------------------------------------------------------Subtotal direct and indirect costs 211.3----------------------------------------------------------------------------Contingency 21.7--------------------------------------------------------------------------------------------------------------------------------------------------------Total Project Capital Cost 233.0--------------------------------------------------------------------------------------------------------------------------------------------------------

Operating Cost

The life-of-mine operating cost is estimated at $88.59 per tonne of concentrate, as summarized in the table below. Additionally, closure costs which include dismantling of all infrastructures and rehabilitation of the Project are estimated at $8 million.

Project opportunities

Reunion has identified the following specific Project opportunities:

-- Potential increase of footprint mineral resources: There are specific areas on the footprint that could not be trenched and drilled in the past because of logistical constraints, but that are known to host mineralized materials. Subject to available financing, these targets will be explored later this year.-- Regional resource development: Three other prospects in the Matthews Ridge region (the Pipiani, Arakaka and North Prospects) are being explored with the objectives of adding new resources in the feasibility study.-- Favorable exploration ground: Reunion holds exclusive exploration licenses for manganese over an area of 185 square kilometers in northwest Guyana considered geologically very favorable for manganese mineralization.-- Potential optimizations: There is considerable scope for optimization of the process plant throughput based on market conditions, increased resources and further metallurgical testing.-- Transportation costs: Ocean freight costs could be significantly reduced if the concentrate is transported by sharing transshipment facilities and bulk carriers currently used for other commodities in the region.

Environmental and social studies

Reunion has conducted the full cycle of environmental and social baseline studies in anticipation of a complete project Environmental and Social Impact Assessment ("ESIA") in conformity with international and local standards. Significantly, no issues have been identified that would hinder project development. The studies have covered two seasons of biodiversity (flora and fauna) data, two years of climate and meteorology, air and water quality, as well as site hydrology data. Social and community baselines have involved documented surveys within and outside the Project footprint area and regular community engagement meetings. Environmental studies were done with the participation of Ground Structures Engineering Consultants Inc., a Guyanese-based company.

A gap analysis by Environmental Resources Management Inc. (ERM), an independent consulting firm based in Washington, D.C., found no major concerns, confirmed the reliability of the existing information and proposed a pathway to the completion of the ESIA for project permitting, which should be completed within the feasibility study period.

Plans for 2013

The pre-feasibility results reported in this press release provide a platform for Reunion to advance the Matthews Ridge Project through to full feasibility. Subject to available financing, the Company's plan for 2013 is to complete an aggressive resource definition program on the Pipiani, Arakaka and North Prospects, upgrade the inferred resources (5.3 million tonnes at 15% Mn) already identified on these prospects and the footprint, and carry out essential work for the full feasibility study.

General 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 (see maps - Figure 1 and 2). Manganese ore was mined from 1960 to 1968 by a subsidiary of Union Carbide and exported via railroad and the Port Kaituma fluvial port (Figure 1).

Manganese deposits have been defined at the Matthews Ridge footprint along a series of nine hills extending for 15 km, of which five were previously mined. Ongoing exploration is focusing on the Arakaka Prospect, which is the eastern extension of the footprint, the North Prospect, which is 5 km to the north of Matthews Ridge, and the Pipiani Prospect, which is located 60 km to the southeast of Matthews Ridge and was already drilled by the previous mine operators (Figure 1).
