“Discovery driven – leveraging Mariana’s expertise and exploration capital to advance projects up the value curve”

The strategy – accumulate and advance a portfolio of potential company maker assets over a defined timeline. Bringing these assets close to feasibility to crystallise and return value to shareholders.

Mariana’s current focus is Gold and Silver and associated minerals with a strategic focus on asset scale, prospectivity and potential without geographical limitations.

Current portfolio within this strategy consists of :

Peru – Short to Medium term diversification strategy in action §  Condor de Oro (‘CDO’) Copper-Gold-Molybdenum Project in Northern Peru: §  Soledad Copper-Gold-Silver Project optioned in Central Peru

Argentina – Pipeline Portfolio longer-term strategy §  Target definition at Los Cisnes – high grade emphasis – strategic consolidation potential §  Las Calandrias and district – strategic Gold Silver bulk tonnage 519,000 Au Eq resource with

potential upside plus regional consolidation

Investment and Exploration Strategy!


AIM: MARL!

5 !2014 Milestones – Mariana actively advancing the Portfolio!

SHORT TO MEDIUM TERM PROJECTS Peru

§  Condor de Oro Au-Cu Project (51%) – Continuing into Second option period – Extend drilling campaign to test 3 new

target areas including ‘Core Zone’ – Drilling Q2

§  Soledad Cu-Au-Ag Project (70%) – Drilling commenced 2000m

programme – 3 holes complete- Hole 1 results out

LONGER TERM PROJECTS Argentina (100%) Au-Ag

§  Las Calandrias and Bozal area – Consolidation & District potential

§  Los Cisnes (high grade and bulk tonnage) – Exciting results from low cost

exploration at Los Cisnes and Bozal – Trenching & sampling Q2 Targeting high grade – Defining scout drill targets

§  Committed milestone-driven explorer

§  Diversified portfolio – focus on deliverable projects

§  Drilling underway at Soledad with 2000m initial drill programme – 3 Holes complete anticipated results up to July 2014 – High grade mineralisation confirmed in Breccia 1 – Adjacent mining operations

§  Drilling H1 at Condor de Oro 2nd year of option period in Peru – 5 holes completed 1641m , drilling programme extended – Potential higher grade “Core Zone targeted” with a further 3-4 holes planned – Results from holes once complete up to July 2014

§  Eastern Deseado Argentina – adapted to current downturn in Argentina but strategic exploration – Exploration funding received with US$600,000 VAT refund – Target definition at Los Cisnes and Bozal – excellent upside and high grade emphasis – Las Calandrias – strategic bulk tonnage resource and potential upside

“Discovery driven – capacity to advance projects up the value curve”
