Drilling on Carube/Miocene Bellas Gate Project in Jamaica Intersects 297 Metres of Robust Copper-Gold Porphyry Mineralization

Toronto, Ontario--(Newsfile Corp. - August 7, 2014) - Miocene Metals Limited (TSXV: MII) ("Miocene") and Carube Resources Inc. ("Carube"), a private Ontario-based exploration company, are pleased to announce that drilling by Carube's joint venture partner, OZ Minerals Limited ("OZ Minerals") at the Connors prospect ("Connors") in the south-central part of the Bellas Gate Joint Venture ("BGJV") in Jamaica has continued to intersect significant copper-gold mineralization. Two drills with better capacity and a smaller environmental footprint are currently being mobilized to continue the drill program at an accelerated pace later this month.

Hole CON-14-003, the third hole drilled by OZ Minerals at Connors, intersected significant copper-gold porphyry mineralization from near surface to 331 metres, similar to the first two holes drilled at Connors (see press release dated June 26th, 2014). It also contained two higher grade intervals in excess of 1.0% copper equivalent.

Assay results from CON14-003 include:

• 297.0 metres of 0.40% copper ("Cu") and 0.24 grams gold per tonne ("g Au/t") or 0.54% CuEq from 34 to 331 metres,

Including

• 55 metres of 0.67% Cu and 0.59 g Au/t or 1.01% CuEq from 86 to 141 metres; and,

• 27 metres of 0.85% Cu and 0.32 g Au/t or 1.04% CuEq from 279 to 306 metres.

Assays have now been received for holes CON-14-001, CON-14-002 and CON-14-003. A summary of the results from all three holes drilled at Connors (as reported by OZ Minerals in their Summary Activity Report to Carube dated July 28th, 2014) are presented in the following table.

Intervals calculated using unlimited internal dilution. Copper equivalents are calculated using a US $3.00/lb. copper and a US$1200 per ounce gold price assuming 100% recovery of both metals. Intersections are drilled lengths only. Too little information is available to estimate actual true widths.

All three holes at Connors intersected copper-gold porphyry mineralization and associated alteration, primarily within intrusive rocks of monzonite composition. Alteration appears to be mostly characterised by an early, intense and pervasive biotite-magnetite event followed by multiple events associated with various vein phases. A number of vein styles are observed including pyrite, pyrite-magnetite, magnetite-pyrite-chalcopyrite, quartz+-magnetite+-chalcopyrite, chalcopyrite, sericite and feldspar; anhydrite and calcite typically being clearly later than other vein phases. Trace bornite and molybdenite are occasionally observed, typically within quartz veins. The presence of crowded feldspar porphyry breccia dykes in all holes is of possible significance. These dykes are finer grained with the matrix being juvenile monzonite porphyry. The dykes are locally well mineralised by sheeted pyrite-chalcopyrite and chalcopyrite veinlets and disseminated chalcopyrite and are interpreted as being syn-mineralization.

Vern Rampton, President and CEO of Carube stated, "The results from the third hole at Connors confirm the presence of a robust copper-gold porphyry system with excellent potential for expansion." Dr. Rampton also commented, "OZ Minerals is also making excellent progress with its surface work on a number of the other high priority target areas at the BGJV. Most exciting is the previously unrealized widespread occurrence of surface copper mineralization at the Hendley prospect as described below."

BGJV Drilling Progress

Five holes totalling 1,652.9 metres have been drilled to date. Three holes have been completed at Connors and two holes have been completed at the Ginger Ridge prospect ("Ginger Ridge"), which is about one kilometre to the north of Connors. A total of 1,807 drill core samples have been forwarded for analysis. In addition, detailed mapping has been completed at both prospects.

Connors

Results from Connors are reported above. Drilling is expected to recommence upon the arrival of two drills in Jamaica for continuation of drilling on the BGJV.

Ginger Ridge

Two holes completed at Ginger Ridge intersected a package of andesitic rocks that have been strongly and commonly pervasively altered; biotite and magnetite being significant alteration products. This alteration is overprinted by potassium feldspar selvages to pyrite-magnetite stockwork veining. Veining is often intense and the feldspar selvages coalesce. Although the alteration and stockwork veining suggests the nearby presence of a significant copper-porphyry system, no significant mineralization has been observed in holes drilled to date at Ginger Ridge. Additional information on this target will be provided by the airborne geophysics and whole rock geochemistry which will be used to prioritize further drilling.

Work on Other BGJV Targets

Work in preparation for drilling has been initiated on three of the other twelve targets identified on the property. Following completion of one or two more holes at Connors, one of the two drills currently being mobilized will start testing these additional targets while the other continues the drilling at Connors.

Hendley

Reconnaissance work at Hendley, located approximately 5km north-west of Connors and proximal to the northwest extremity of Porphyry Alley, has identified strong copper oxide mineralisation at surface in several locations. A soil sampling program has been completed over a 1.5km x 1.0 km area. Intensely altered rocks with strong neotocite and malachite mineralisation were recovered from several hand-dug soil sample holes at depths of 30-50cm. The malachite occurs primarily as disseminations and less frequently in veins. Assays are pending. Detailed mapping is currently underway. Results of the mapping and airborne geophysics will be used to direct initial drilling of the Hendley prospect on a priority basis.

Kola

Detailed (1:1000 scale) mapping at the Kola Prospect, located approximately 4.5km south-east of Connors, has identified a zoned, porphyry-style alteration system, approximately 1.1km long by 700m wide. This correlates well with the historic copper soil geochemical anomaly, as well as historic airborne magnetic and radiometric data. A water extraction licence has been applied for and received and drill hole locations are currently being planned.

Porphyry Alley

A soil sampling program has also been completed covering the approximately 1.4km strike length of the Porphyry Alley prospect from Camel Hill in the southeast to Geo Hill in the northwest. Assays are pending.

Re-logging of Historic Core

Drill core from several key historic drill holes from the Porphyry Alley and Bull Snap targets has been located in storage at the Mines and Geology Division in Kingston. Two of the holes have been re-logged and the same alteration and mineralisation styles identified in drill core from Connors have been observed. Both of these prospects are within two kilometres of Connors. Once re-logging of the remaining holes is complete, follow-up work programs will be planned and prioritised for these areas. The key association between magnetite and copper mineralisation present at the above prospects, highlights the importance of the upcoming detailed helicopter magnetic and radiometric survey of the entire Bellas Gate Project for location of mineralized porphyries.

Airborne Geophysics

A contract has been signed with MPX Geophysics and detailed helicopter magnetic and radiometric surveying of the entire Bellas Gate Project area will commence shortly, followed by surveying of two of Carube's other Jamaican licenses, Belvedere and Mt Royal, which together comprise the Above Rocks Project and contain several high priority target areas. Prior to July 21^st 2015 OZ Minerals must complete airborne geophysics over Carube's other two Jamaican licences to keep their Option for a joint venture in good standing. Upon completion of flying the airborne geophysics over the other projects, OZ Minerals will have six months to elect to enter into additional joint ventures on one, two or all three of the projects. If OZ Minerals elects to enter into one or more new joint ventures in regard to any of these properties, the joint venture terms for each project will allow OZ Minerals to earn a 70% interest in any of the projects by spending $6.5 million on exploration per project and making option payments totalling $275,000 per project to Carube over a five year period.

Sample Preparation, Analysis and Quality Control: Drill core (HQ3 and NQ3) was stored at a secure compound at Bellas Gate where it was subsequently examined. All core was then sawed in half and the split core from 1m± intervals, which weighed approximately 2kg, was bagged individually. Five to ten samples were then packaged in rice bags and boxed for shipping by bonded courier to Activation Laboratories Ltd (ActLabs) in Ancaster, Ontario. At ActLabs the samples were crushed with up to 90% passing 2mm, 1000g was then rotary split and pulverized to 95% passing 105 micron. ActLabs Ultratrace 5 (Au+58) procedure was employed with INAA used to determine Au, As, Sb, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, Hg, Ir, La, Lu, Na, Nd, Rb, Sc, Se, Sm, Sn, Ta, Th, Tb, U, W and Yb contents. The remainder of the elements – Ag, Al, B, Be, Bi, Ca, Cd, Cu, Hf, K, Li, Mg, Mn, Mo, Ni, P, Pb, S, Sr, Ti, Y and Zn – has their values determined by ICP-MS following 4-acid digestion.

ActLabs is a fully accredited laboratory to ISO 17025 and CAN-P-1579 and NELAP standards. A number of Certified Reference Material standards using both oxide and hypogene matrixes as appropriate and coarse and pulp blanks are inserted into the sequence of samples to be analyzed. Approximately 20% of the samples submitted for analysis are for quality control.
