NDABLAMA DRILLING EXPANDS MINERALISED SYSTEM

Aureus Mining Inc. (TSX: AUE / AIM: AUE) ("Aureus Mining" or the "Company") is pleased to announce an additional eleven diamond drill hole results from the phase four drilling programme at the Ndablama gold project ("Ndablama"), following on from the initial results announced on 27 January 2014. Ndablama locates within the Northern block of the Company's 100% owned, Bea Mountain Mining licence in Liberia, 40 kilometres north-east of Aureus' flagship New Liberty Gold project.

Highlights

· Results are presented for eleven diamond drill holes (2,542 metres) from the phase four drilling programme at Ndablama. Drilling was undertaken on the down dip and northern extensions to the current Inferred Mineral Resource of 451,000 ounces at 2.1 g/t Au. Intercepts include:

2.7 g/t over 20 metres from 211 metres

13.5 g/t over 3 metres from 193 metres

3.3 g/t over 11 metres from 108 metres

2.7 g/t over 13 metres from 186 metres

2.8 g/t over 8 metres from 251 metres

2.2 g/t over 9 metres from 253 metres

· Phase four results received to date (21 holes) confirm continuity of the mineralised system down dip for another 250 metres beyond the limits of the maiden resource, doubling the down dip extent of the mineralised system. Intercepts commence from 90 metres below surface to a maximum of 180 metres below the surface. To date all drill holes have intersected the mineralised system and confirm the shallow westerly dip of about thirty degrees. The mineralised body is still open in all directions.

· Geological mapping, soil geochemistry, trenching, geophysics and previous reconnaissance drilling have outlined a five kilometre mineralised structural zone which dips shallowly to the west and locates at the sheared and altered contact between granite and metavolcanics. This zone is referred to as the pressure shadow corridor. It is associated with extensive bedrock and alluvial artisanal gold mining. Recent work has outlined that this zone can be followed at surface over the total five kilometre area.

· The phase four drilling programme is designed to expand the current Inferred Resource both down dip and along strike. A total of 50 diamond drill holes for approximately 10'000 metres are planned over a target area that strikes north for one kilometre, extends down dip for vertical depths of 200 metres below surface and encompasses the target now referred to as Ndablama Central zone. Drilling is on-going with seventy per cent of the programme completed to date.

· The Company's exploration team continues to actively explore the whole five kilometres of the pressure shadow zone. Trenching and detailed soil sampling confirm continuous mineralisation northwards from Ndablama Central. To the south, rock chip and soil sampling and trenching confirm that there is no longer a gap between Ndablama and Leopard Rock and that the mineralised system continues for a further two kilometres.

Commenting on the latest Ndablama drilling results, David Reading, President and Chief Executive Officer of Aureus Mining, said:

 "The latest drilling results at Ndablama highlight the contiguous nature of what appears to be an extensive mineralised system, linking the deposits of Leopard Rock with Ndablama. This system is both open down dip and along strike and the opportunity of defining further resources in the large pressure shadow corridor provides yet further upside to the Ndablama discovery. Aureus remains on track to deliver an expanded Resource at the end of the current field season. We are very excited about the opportunity that this new goldfield presents for our shareholders".

Ndablama Background

The Ndablama gold target is located within the Northern block of the Company's 457 km2, 100% owned, Bea Mountain Mining licence in Liberia, and is situated approximately 40 kilometres north-east of Aureus' flagship New Liberty Gold project. To date a total of 75 diamond drill holes covering 13,352 metres and 63 trenches for 3,967 metres have been completed at the Ndablama gold target. The majority of drilling and trenching has been focused in the Ndablama Central area with some reconnaissance drilling undertaken at Leopard Rock. Geological mapping and trenching has now been undertaken over the whole pressure shadow zone.

The mineralization is located within a sheared package of intercalated ultramafic and mafic rocks which are enveloped by a gneissic sequence and overly a granite batholith. The mineralization has a shallow westerly dip reaching on average 30° and striking to the North. It has been drill investigated to a maximal vertical depth of 180 metres below surface. It remains open along strike and down dip.

The latest phase four drilling results are presented below:

Drilling to date has shown that mineralisation is hosted in sheared and altered metavolcanics which dips shallowly to the west at approximately 30o. Mineralisation is associated with phlogopite, chlorite alteration and disseminated pyrrhotite.

Of the 11 drill holes reported in this release, 9 holes tested the down dip extension of the mineralisation and confirm that it can be followed for another 250 metres down dip effectively doubling the downdip continuity of the mineralised system.. The maiden Inferred resource of 451,000 at 2.1g/t, as reported on 11 November 2013 was based on only 250 metres of down dip mineralisation. The current maximal vertical depth that the mineralised zone has been intercepted is now 180 metres below surface. Holes NDD073 and 74 drilled to test the first portion of Ndablama North both confirm mineralisation continuity but with some lower grades. Further drilling is required in the North and South as the mineralisation is open in both directions as well as downdip.

The phase four drill programme is ongoing within the Ndablama North and Central zones, with the aim of expanding the current NI 43-101 Inferred Resource of 451,000 oz grading 2.1 g/t Au. Drilling started in November 2013 and will continue throughout the remainder of the current field season. To date 21 holes totalling 5038 m from a planned 50 hole and 10'000 m programme have been reported with further results pending as over seventy per cent of the programme has been completed to date. The drill programme will continue testing the down dip extension of the full 1 km strike extent of the Ndablama Central target area.

Ndablama is situated within a five kilometre pressure shadow zone and is an area of extensive artisanal gold activity

The Ndablama gold project locates within a five kilometre mineralised, structural zone which dips shallowly to the west and occurs at the altered and sheared geological contact between Metavolcanic rocks (ultramafic and mafic units) and granite. This target is referred to as the pressure shadow zone ("PSZ"). The PSZ extends from Ndablama Far North to Leopard Rock South and covers a distance of five kilometres. It is associated with extensive bedrock and alluvial artisanal gold mining. To date less than 20% of the pressure shadow corridor has been drill tested.

Resource expansion work is currently being undertaken at Ndablama Central area. To the north and south of the Resource expansion area the Company has undertaken pitting, trenching, rock sampling and geological mapping in order to better delineate the mineralised system in these areas and to define additional targets for follow up drilling programmes. The work completed to date demonstrates that the PSZ can now be followed at surface for over five kilometres

At Ndablama North Zone, geological mapping, soil and rock sampling and trench results demonstrate that gold mineralization can now been traced over a further 1.5 kilometre in a northerly direction. Trenching and pitting is in progress with three trenches completed to date and results pending. At the far north end of the pressure shadow zone, historic trench NNT02 intersected 14 m @ 1.06 g/t and 7 m @ 1.76 g/t.

South of the Central zone results from soil samples and rock samples taken to cover a gap area between Ndablama and Leopard Rocks confirm the presence of continuous and high grade soil anomalism (up to 950 ppb) joining both prospects. A road cut in this area was channel sampled and returned 14 m @ 1.05 g/t. Pitting and trenching is in progress.

Eight hundred metres south east of Ndablama, the Leopard Rock target has been drilled at a reconnaissance level and demonstrated shallow westerly dipping gold mineralisation which is very similar to Ndablama. This drilling has extended the mineralisation system a further one kilometre to the south east. Soil anomalies and artisanal activity indicate that it can be extended for another kilometre south east beyond the known drilling.
