Bonanza Rock Chip Results from Mariana$B!G(Bs New Rurimarac Au-Ag Property, 4km from Soledad Cu-Au-Ag Prospect, Central Peru Mariana Resources Ltd ($B!F(BMariana$B!G(B or $B!F(Bthe Company$B!G(B), the AIM quoted exploration and development company focused in South America (Fig 1), announces that bonanza rock chip channel sampling results from the new strategic 2,000Ha Rurimarac gold tenements ($B!H(BRurimarac Properties$B!I(B) confirm high grade gold and silver mineralisation exposed in pits and outcrop.

Rurimarac is located in the prospective Cordillera Negra metallogenic province in Peru, only 4km west of Mariana$B!G(Bs recently drilled and strongly mineralised copper-gold Soledad project ($B!F(BSoledad$B!G(B) (Fig 2&3).

Rurimarac and Soledad are located in the Aija polymetallic mining district, 34 km south of the Pierina gold$B!>(Bsilver mine that was operated by Barrick Gold Corporation.
The Rurimarac Properties are subject to an earn in option agreement entered into with Tinka Resources Limited ($B!H(BTinka$B!I(B) (TSXV:TK) (announced 8 September 2014).

Tinka currently owns 100% of the Rurimarac Properties through its Peruvian subsidiary Darwin Peru S.A.C.
Overview * Mariana surface sampling at the Rurimarac Properties, which included bonanza results, confirms a zone of high grade gold mineralisation along a low-angle fault zone that has not been drill tested by previous explorers (Fig 4) * Results were received for 79 rock chip channel samples collected in Q3 2014 from 0.4m to 1.5m wide veins exposed in outcrops and pits (Fig 4&5) with numerous samples returning anomalous to bonanza gold assays: o The sampling confirms previous Tinka results - 24 of the 79 samples returned assays >2 g/t Au, of which 19 were >5 g/t Au and 5 were >31 g/t (1oz/t) Au (Fig 5) o Silver was also highly anomalous with 16 samples returning grades >20g/t Ag, including 6 samples with grades greater than 1 oz/t Ag o Identified a strongly altered and oxidized package of siltstones, +25m wide and at least 500m long at a contact with intrusive dioritic (Figs 4&5) in the eastern target area * The main mineralised low-angle fault zone has a 30-40 degree dip to the SW with true thickness of 6m to +30m, and a strike length of at least 1km and one of Tinka$B!G(Bs drill holes only partially tested the breccia zone.

LDD5 (2006) intersected 6m @ 3g/t Au from 60m in oxidised rock (Figs 3, 4) * Engagement with local communities is a priority and a social scoping study is to commence by the end of October 2014 * On-going exploration at the Rurimarac Properties will include drilling at least eight core holes, mostly testing the main breccia structure, subject to approvals.

This will take place in conjunction with the next Soledad campaign Mariana$B!G(Bs CEO Glen Parsons commented, $B!H(BThese high grade bonanza results from our initial sampling on the Rurimarac Properties are extremely encouraging.

They increase confidence in historic high grade assays and indicate the main SW striking mineralized structure is low angle, up to 3m wide and 1 km long oxidised breccia from 6 to 30m true thickness.

Moreover, the main zone has not been drill tested and remains open.

We have already identified new mineralized target areas in this 2,000Ha under-explored property, and intend to commence drilling on at least eight core holes in tandem with our next Soledad drill programme.$B!I(B $B!H(BFurther to the successful initial drilling at Soledad, our earn in option on the Rurimarac Properties has certainly bolstered our presence in Central Peru around Aija with its excellent exploration potential.

This is in line with our strategy to upgrade our portfolio, gear up our exploration activities in this proven district and deliver on exploration milestones in the coming months.$B!I(B

Rurimarac Sampling - Summary
* Mariana can earn a 70% interest in the Rurimarac Properties subject to the agreement (announced 8 September 2014) * The properties are located within the Aija polymetallic mining district, in the department of Ancash in northern Peru, 4 km west of Mariana$B!G(Bs copper-gold Soledad project and 34 km south from Barrick$B!G(Bs Pierina gold mine (see Fig.

2) * The main mineralized structure is NW striking, dipping 30 degrees SW, up to 3m wide and 1 kilometre long oxidised breccia structure, hosted by a diorite intrusive, and located on the western part of the target area near the contact with Mesozoic sedimentary rocks (Figs 4, 5) * Mariana identified a strongly altered and oxidized package of siltstones at the eastern part of the target area, more than 25m wide and at least 500m long at the contact with the dioritic intrusive (Fig 4,5) * Last Quarter, Mariana collected 79 channel samples from mineralized 0.4m to 1.5m wide veins exposed in outcrops and pits (see Fig.

5).

Results returned: o high grade gold assays with 24 samples grading between 2.5 g/t and 53.8 g/t; o high grade silver, with 17 samples yielding between 15 g/t and 83 g/t Ag. o Anomalous copper, lead and zinc values with grades up to 0.19 % Cu, 0.5 % Pb and 0.16 % Zn * Most rock chip samples along the main zone were vertical channels perpendicular to the structure taken from pits spaced at approximately 50m along the zone * Previous sampling of trenches and pits on the property by Tinka Resources in 2006 averaged 5.1 g/t Au, ranging from 0.1 g/t to 39 g/t Au * Tinka drilled six holes targeting IP geophysical anomalies away from the main geochemical anomaly.

However, drillhole LDD-5 tested the southern part of the main breccia target zone and significantly intersected 6m @ 3.3 g/t Au from 60m.

The last 20m, from 180m to bottom, cut siltstones with disseminated chalcopyrite mineralization, assaying 0.1 % Cu (Figs 4,5) * The on-going exploration programme at the Rurimarac Properties will include: o further surface mapping and rock chip sampling to extend the target in the southern part of the property, and o drilling at least eight core holes, six of which will target the main breccia structure at the upper contact of the diorite intrusive and two the lower contact of the diorite with the altered and oxidised siltstone package * Mariana is planning a social scoping study of communities local to Soledad and Rurimarac to ensure the early engagement with local stakeholders * A renewed drill permit will be submitted to the Peruvian Ministry of Mines shortly to allow drilling activities to start at the Rurimarac Properties around the same time as the Soledad campaign
Soledad - Rurimarac 2014/2015 programme Mariana is receiving quotes for deeper sensing Geophysics at Soledad to assist in the targeting of proximal centres of porphyry mineralisation in the next round of drilling.

Compilation of all results to date, updating the geological model and generating further drill targets within the 1km diameter target area are in progress.
* Mariana$B!G(Bs exploration programme at Rurimarac will include further surface reconnaissance aiming to extend the target in the southern part of the property, and drilling at least eight core holes described above * Mariana will start at the end of October 2014 with a social scoping study of the communities in the area for Soledad and the Rurimarac Properties, ensuring communities are engaged at an early stage * Mariana will file within six months a renewed drill permit ($B!H(BDIA$B!I(B) and drill an initial 1,500m following approval Key Rurimarac Option Terms for Mariana: * No option payments, only work commitment earn in * Lodge the renewed drill permit within six months * Drill 1,500m within 12 months of approval to attain a 51% interest * Mariana can earn a further 19% by lodging the next stage of drill permit and drilling a further 3,000m within two years of attaining a 51% interest
Summary results of Mariana$B!G(Bs drilling to date at Soledad At Soledad the Company recently completed a successful diamond drill programme which tested a combination of targets including high level porphyry, strongly mineralised quartz$B!>(Btourmaline breccia pipes, breccia root zones and adjacent concealed porphyry targets all within a 1.0 km diameter area of interest.

The results have yielded strong breccia mineralisation and have given Mariana confidence in planning its next phase of exploration alongside its exploration at the Rurimarac Properties.
