NDABLAMA FINAL DRILL RESULTS HIGHLIGHT GOOD GRADES

Aureus Mining Inc. (TSX: AUE / AIM: AUE) ("Aureus Mining" or the "Company") is pleased to announce results from the remaining 49 holes of the phase four drilling programme at the Ndablama gold project ("Ndablama"). These results follow those announced on 27 January, 7 April and 10 July 2014. The phase four drilling programme included a total of approximately 19,000 metres of reverse circulation ("RC") and diamond drilling. The RC drilling targeted the infill areas between diamond holes previously drilled, with the new diamond holes testing for down dip and strike extensions to the current mineralised system. Ndablama is located 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 the final 24 diamond drill holes (4,101 metres) from the phase four drilling programme at Ndablama. Drilling was undertaken to test the down dip and strike extensions to the 2013 Inferred Mineral Resource of 451,000 ounces at 2.1 g/t Au, released on the 11 November 2013. Intercepts include:

3.0 g/t over 28 metres from 139 metres

3.0 g/t over 22 metres from 98 metres

2.8 g/t over 24 metres from 88 metres

3.3 g/t over 18 metres from 123 metres

2.3 g/t over 24 metres from 95 metres

· All drill holes have intersected the mineralised system and confirm the shallow westerly dip varying between 30 and 10 degrees.

· Phase four diamond drilling results confirm continuity of the mineralised system down dip for a further 300 metres beyond the limits of the initial maiden resource, more than doubling the down dip extent of the mineralised system. Intercepts commence from 90 metres below surface to a maximum of 240 metres below the surface. The mineralised zone was extended southwards by a further 100 metres and remains open northwards.

· The results announced today also include the remaining 25 RC drill holes (3,480 metres) carried out as infill holes in advance of upgrading the current inferred resource. Intercepts include:

6.2 g/t over 45 metres from 85 metres

2.9 g/t over 23 metres from surface

2.5 g/t over 21 metres from 38 metres

2.4 g/t over 22 metres from 71 metres

2.2 g/t over 16 metres from 103 metres

2.3 g/t over 11 metres from 185 metres

· The infill RC drilling results confirm mineralisation continuity within the already defined ore body. This programme was designed to close the drill spacing down to 50 metres.

· Following receipt of the phase four results, the Company is to commence a new NI 43-101 Resource estimate for Ndablama, due for completion in Q4 2014.

· Further metallurgical studies are currently being conducted on the Ndablama deposit. These studies follow initial work conducted in 2013 which highlighted 70% gravity recovery and 94% leach recovery for fresh ore (see press release of the 10 December 2013).

· Ndablama forms part of a five kilometre long pressure shadow corridor. Exploration work has confirmed that gold mineralisation is associated with a shallow, westerly dipping shear zone which can be followed at surface for five kilometres. To date only Ndablama and Leopard Rock have been drill tested. Exploration conducted on Ndablama Far North and Leopard Rock South returned encouraging trench and rock results and these targets are ready to be drill tested.

· Towards the north-east the pressure shadow corridor connects to the Yambesei Shear Zone which is highlighted by continuous soil anomalies extending over 8 kilometres. This steep dipping shear zone straddles along the northern edge of the Ndablama granitoid. Reconnaissance work along this shear corridor has outlined four gold targets for follow up drill programmes.

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

"The phase four drilling programme continues to return excellent results. We believe that the Ndablama target is part of a new goldfield which can be traced for over thirteen kilometres around a granite body and to date only 15% of this area has been drill tested. The Company now looks forward to developing an upgraded resource during the next quarter."

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 115 diamond drill holes covering 21,322 metres, 39 RC infill holes totalling 5,828 metres and 63 trenches for 3,967 metres have been completed at the Ndablama gold target. Ndablama locates within a five kilometre gold bearing pressure shadow zone which is defined by a shallow, westerly dipping shear zone locating near the contact between granite and greenstone rocks. Geological mapping and trenching has now been undertaken over the whole pressure shadow zone.

Gold 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 of 30° or less and strikes to the North. It has been drill investigated to a maximal vertical depth of 240 metres below surface. It remains open along strike and down dip.

The phase four diamond drill programme that started in November 2013 was completed in early August 2014 for a total of 61 holes totalling 13,000 metres. The results for the remaining 24 holes (NDD092 to NDD115) are presented below.

NDD104: abandoned hole

Drilling has shown that mineralisation is associated with phlogopite, silica, chlorite alteration and disseminated pyrrhotite. Detailed examination of cores consistently shows the presence of coarse gold. Initial metallurgical testwork results which were announced on 10 December 2013 returned an average of + 70% gravity recovery from the fresh ore, which will have a positive impact on the plant design.

Of the 24 diamond drill holes reported in this release, fifteen holes tested the down dip continuation of the ore body. These drill holes returned good mineralisation within the main part of the ore body. 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, while the phase four diamond holes have extended it by an additional 300 metres. The current maximal vertical depth that the mineralised zone has been intercepted is now 240 metres below surface. Two holes (NDDH092 and 93) tested the immediate northern extension of Ndablama and confirmed further mineralisation continuity. Three holes (NDD111 - 113) testing the southern extension extended the mineralisation by an additional 100 m towards Leopard Rock.

The results of the remaining 25 holes of the infill RC program are presented below:

NDRC027: Abandoned hole due to ground conditions

NDRC028: NSR

NDRC031: Not reported due to poor recovery from the oxide mineralised zone

The results of the final 25 infill holes confirm the continuity of mineralisation within the already defined ore body. This programme undertaken between May and July 2014 was designed to close the drill spacing down to 50 metres from Ndablama's central portion in prevision of upgrading the resource confidence in early Q4 2014. The bulk of the infill holes targeted a 400 metre north-south strike length by a 350 metre down dip length (maximal depth is 150 metres). The infill programme is now complete for a total of 39 holes and approximately 5,828 metres.

Now that all the results for the phase four drilling programme are received, the Company is undertaking a new NI 43-101 Resource estimate for Ndablama, due for completion in Q4 2014. Metallurgical studies are currently been conducted on the Ndablama deposit following initial studies undertaken in 2013 which highlighted 70% gravity recovery and 94% leach recovery for fresh ore (see press release of the 10 December 2013).

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

The Ndablama gold project is part of a thirteen kilometre mineralised corridor, of which five kilometres is represented by a shallow shear pressure shadow zone and the eight other forms part of a steeper shear system, referred as to the Yambesei Shear Zone. The Ndablama gold project locates within the five kilometre pressure shadow zone which is characterised by a mineralised structural zone which dips shallowly to the west and occurs close to the altered and sheared geological contact between metavolcanic rocks (ultramafic and mafic units) and the Ndablama granitoid. The pressure shadow zone extends from Ndablama 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 only 40% of the pressure shadow zone has been drill tested.

Extensive geological mapping has now completed over the whole pressure shadow zone. At Leopard Rock South where a 400 metres long mineralised zone was previously defined through trenching (press release of the 10 July 2014), new soil anomalies resulting from additional infill soil sampling have extended the mineralisation trace for a further 200 m towards SW. This is further confirmed by rock sample results returning grades up to 1.9 g/t Au. The previously reported trench results from Leopard Rock South include 8 metres at 1.2 g/t, 10 metres at 1.3 g/t, 11 metres at 1.6 g/t and 7 metres at 2.3 g/t. At Ndablama Far North, the best trench results that have been previously reported include 14 m @ 1.1 g/t and 7 m @ 1.8 g/t. Within the pressure shadow zone, Leopard Rock South and Ndablama Far North now represent targets ready to be drill tested while the remaining of the mineralisation system needs further follow up work.

Within the Yambesei Shear Zone regolith mapping show that a number of soil anomalies remain untested. A pitting program undertaken in the Gondoja-Welinkua area has led to the discovery of two new mineralised zones. The first zone extends over 600 m and runs parallel to the Gondoja existing mineralised zone. It is controlled by a NE structure developed between amphibolites and ultramafics. The second zone is located at Welinkua and strikes over more than 300 m along a contact between amphibolites and a granitoid. Pits in both locations returned grades up to 1.6 g/t. The pitting program will continue testing other soil anomalies along the corridor while existing targets will be reviewed and be subject to follow up work. Gondoja target is currently the most advanced target with historic best trench and drill results having returned respectively 7 m @ 13.1 g/t and 30 m @ 3.9 g/t. Best trench results at Gbalidee and Koinja are resp. 22 m @ 3.4 g/t and 6 m @ 2.2 g/t. The existing targets and potentially new targets will be prioritised for next phases of reconnaissance drilling.
