January 17, 2017

This morning Mariana Resources released the PEA for the Hot Maden Gold/Copper Project in Turkey. This project has been producing some amazing gold and copper grades and the PEA further showed how well this deposit is shaping up. Some of the highlights include an NPV of $1.37 billion (post-tax), a payback period of just over 2 years and a post-tax IRR of 153%.

I will be chatting with Glen Parson this week and featuring him on the weekend show. Stay tuned for what he has to say. In the meantime here is the news.

Hot Maden High Grade Gold-Copper Project– PEA Results with a Positive IRR of 153%

Mariana Resources Limited (‘Mariana‘ or ‘the Company’), the TSX.V and AIM (MARL) listed exploration and development company with projects in Turkey, South America, and Ivory Coast, is pleased to announce a highly favourable outcome for a Preliminary Economic Assessment (“PEA” or the “Study”) of the high grade Hot Maden gold-copper project in NE Turkey. The PEA was prepared in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) by independent mining consultant firm RungePincockMinarco Limited (“RPM”).

Highlights of the Study (100% Project Basis)

  • Conceptual development for Hot Maden assumes an all underground mining operation from a decline and utilizing mechanized transverse and longitudinal long hole open stoping with engineered fill mining methods. Mining and processing rates of 0.8 million tonnes per annum (“Mtpa”), 1.0 Mtpa, and 1.2 Mtpa were considered, with the base case mining scenario being established at 1.0 Mtpa.
  • Total metal production of 2.6 Million ounces (“Moz”) of gold and 142,000 tonnes (“t”) of copper over a total project life of 9 years for the base case mining scenario. Metallurgical testwork, through flotation and concentration, completed to date on the high grade Main Zone mineralisation has indicated high recoveries of both gold and copper. A variable processing recovery, dependant on grade, has been applied in the PEA resulting in a project weighted average recovery of 88% Au and 90% Cu. The current Hot Maden plant flow sheet assumes the production of two concentrates on site – one standard copper-gold concentrate, and a second gold-bearing pyrite concentrate.
  • Post-tax discounted NPV for the base case mining scenario (1.0 Mtpa) of US$1.37 billion (“B”) excluding pre-development exploration costs (8% discount rate).
  • Post-tax IRR for the base case mining scenario of 153% excluding acquisition costs.
  • Total Capex (Initial + Sustaining) of US$261M

Note that the PEA is preliminary in nature as it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves.  Mineral resources that are not mineral reserves do not have demonstrated economic viability, and as such there is no certainty that the preliminary assessment and economics will be realized. A NI-43-101- technical report for the Hot Maden PEA will be filed on SEDAR (www.sedar.com) within 45 days and also be posted on Mariana‘s website (www.marianaresources.com).   

The Hot Maden project is 70:30 Joint Venture between Turkish partner Lidya Madencilik Sanayi ve Ticaret A.S. (“Lidya”) and Mariana Resources Ltd.

Chief Executive Officer Glen Parsons today commented:

“The potential value is finally revealed from the high grade Au-Cu Hot Maden project with these PEA results from RPM.  We have always believed Hot Maden to be a world class deposit and, with a potential post-tax NPV for the base case mining scenario of $1.37B and post-tax IRR of 153%, this is certainly proven correct.  The high grade nature of this resource and relatively low capital (CAPEX) and operating (OPEX) costs should result in the delivery of considerable cashflow and a short payback period (around 2.1 years, including underground mine development) on initial investment.

Despite Hot Maden’s rapid advancement from discovery to PEA in just 20 months, the decision by the Lidya/Mariana (70/30) joint venture to rapidly move to development is justified with the value of the project for shareholders reflected in the significant cash flow generative ability through the life of this initial current resource. The result is expected to be a low cost, low environmental footprint, but highly profitable mine.

A further 20,000m of drilling is budgeted and planned for this new year and we must remember that exploration drilling continues to focus on the discovery of new gold-copper resources at Hot Maden, especially to the south of the Main Zone within the old “Russian Mining Area.

The Joint Venture will also continue to work on the technical studies and optimisations required to underpin the Preliminary Feasibility Study (“PFS”), which is anticipated to be completed during Q3, 2017. The PFS will provide higher confidence level mine designs, mineral processing scenarios, and costings for the Hot Maden Project.  Therefore this result could change over time based on the updated prices, resource and assumptions.

I look forward to updating the market on developments, as 2017 will continue to be a busy period for Mariana.”

Geology and Mineral Resources
The high grade gold-copper mineralisation at Hot Maden occurs within a N-NE-trending fault zone (the “Hot Maden Fault Zone”) and is sub-vertical in nature. At least two styles of gold-copper mineralisation are evident within the Main Zone: i) the predominant, multiphase quartz-sulphide (pyrite-chalcopyrite) +/- hematite/jasperoid breccia bodies, and ii) semi-massive to massive sulphides (pyrite-chalcopyrite). Host rocks are dominantly andesites and andesitic breccias. Overall, the highest-grade gold mineralisation (typically >15 g/t Au but locally >100 g/t Au) at Hot Maden lies along the eastern margin of the Main Zone. Drilling is ongoing but the current dimensions of the Main Zone are a strike extent of 300 m from north to south, a true width of between 50m and 70m, and a vertical extension from near surface to >300m depth.  Stratabound Zn(-Pb) (sphalerite-galena) mineralisation also flanks the Main Zone to the east and locally to the west. In the new Southern Vein Field discovery, host rocks are dominantly dacitic breccias and gold-copper mineralisation is associated with quartz-sulphide-bearing veins and vein breccias.

On July 25, 2016, Mariana reported an updated Mineral Resource for the Hot Maden project.  This Resource Estimate was prepared by independent mining consultants RungePincockMinarco, and was based on assay results received for holes up to, and including, HTD-62. The Mineral Resource Estimate for Hot Maden included contributions from both the Main Zone and a new Southern Discovery, and comprises (on a 100% basis):

*Au Equivalence (AuEq) calculated using a 100 day moving average of $US1,215/ounce for Au and $US2.13/pound for Cu as of May 29, 2016. No adjustment has been made for metallurgical recovery or net smelter return as these remain uncertain at this time. Based on grades and contained metal for Au and Cu, it is assumed that both commodities have reasonable potential to be economically extractable.

  1. *-The formula used for Au equivalent grade is: AuEq g/t = Au + [(Cu % x 22.0462 x 2.13)/(1215/31.1035)] and assumes 100 % metallurgical recovery.
  2. **-Au equivalent ounces are calculated by mulitplying Mineral Resource tonnage by Au equivalent grade and converting for ounces. The formula used for Au equivalent ounces is: AuEq Oz = [Tonnage x AuEq grade (g/t)]/31.1035

In addition, a maiden Inferred Mineral Resource for the hanging wall zinc zone of 2.8MT @ 4.0% Zn (2% Zn cut-off) was reported. However, this zinc resource has not been considered in the current PEA, although future technical studies will consider the potential economics of mining this mineralised zone.

Mining Method and Mineral Processing
Mining of the wide, near vertical gold-copper mineralisation in the Hot Maden Main Zone is expected to be undertaken through underground mining using underhand, mechanised transverse and longitudinal long hole open stoping (LHOS) with engineered fill mining techniques. The Stopes are mined using an underhand extraction sequence (Top Down) utilising a primary/secondary stope extraction methodology to exploit the grade profile, which diminishes with depth.
The Hot Maden project is divided into two main areas, North and South. The northern area consists of the wider portion of the ore body and as a result is modelled predominantly transverse LHOS to maintain the production rate. Some stopes less than 20m long and/or wide have been developed longitudinally.

The southern portion of the mineralisation is thinner and has been modelled in a longitudinal LHOS layout. This has been carried out so as to reduce the amount of capital development required for access to this mineralisation.

Access to the north and south areas are by independent declines. The northern decline is accessed by a box cut portal whereas the southern portal is an adit into the hill.

The PEA reviewed 0.8 Mtpa, 1.0 Mtpa and 1.2 Mtpa production profiles at a range of NSR COG’s from USD50/t to USD200/t. NSR was used instead of the gold equivalent used in the Mineral Resource to capture the full value of all mining blocks due to the relationship and variability in grade, processing recoveries, concentrate recoveries and post gate costs. The base case mining scenario was identified as 1.0 Mtpa, however, an achievable optimum economic outcome was identified at a production rate of 1.2Mtpa and NSR cut-off-grade of USD 100/ in situ tonnes (this NSR cut-off equates to an approximate 3.3g/t AuEq cut-off grade).

A variable processing recovery, dependant on grade, has been applied in the PEA resulting in a project weighted average recovery of 88% Au and 90% Cu. The current Hot Maden plant flowsheet has been demonstrated on Life of Mine (LOM) composites with the production of two concentrates – a typical copper gold rich concentrate (~25% Cu and 85 g/t Au) and a gold-bearing pyrite concentrate. The flowsheet is currently being tested on ‘Ultra High Grade’ (UHG) composites. The incorporation of a gravity concentrator has been included for gold ores in excess of 100 g/t Au.

Processing and Infrastructure Capital Costs
The processing plant and associated site infrastructure is estimated to cost USD 80.1 million including contingency and owner’s costs. Off-site infrastructure is estimated to cost USD 45.2 million including contingency.

Overall, the processing and infrastructure costs are estimated at USD 125.3 million.

Project Economics and Sensitivities

The project is most sensitive to changes in Metal price (namely combined Copper and Gold prices), most significantly Gold price, processing recovery and mining recovery.
