Mirasol Signs a Heads of Agreement with Newcrest Mining for the Gorbea Gold Projects in Chile and Announces Termination of the Zeus Agreement

December 10, 2018

VANCOUVER, BC, December 10, 2018  Mirasol Resources Ltd. (TSX-V: MRZ, OTCPK: MRZLF) (the “Company” or “Mirasol”) is pleased to report that it has entered into  a non-binding heads of agreement (the “HoA”) with Newcrest International Pty Limited, a wholly owned subsidiary of Newcrest Mining Limited (ASX: NCM)(“NCM”), for an Option to Farm-in on the Gorbea High-Sulfidation Epithermal (HSE) gold projects (the “Project”) in Chile, and is terminating the previously announced (news release February 26, 2018) NCM option agreement on the Zeus Project (Figure 1).

The Gorbea HoA is subject to NCM completing its due diligence review of the claims and the parties executing a formal option agreement (the “Agreement”) on or before January 15, 2019 or such later date as may be agreed. The key terms of the Agreement having been settled, the parties will execute the final Agreement once due diligence has been completed. Mirasol has granted an exclusivity period to NCM to complete these conditions.

 The Gorbea Project comprises a package of projects totaling 26,684 ha, including the Atlas Au+Ag and the Titan Au (Cu) projects, located in the Mio-Pliocene age mineral belt of northern Chile.  The Gorbea properties were subject to a previous joint venture that was terminated in April 2018, after the partner had incurred exploration expenditures in excess of US$ 8 million. The exploration identified a significant body of HSE gold mineralization at the Atlas project, which returned a drill intercept of 114 m grading 1.07 g/t Au, including 36 m grading 2.49 g/t Au (news release September 11, 2017). Mirasol is undertaking an integrated analysis of the extensive Atlas database and will provide a technical update on the project in the near term.

Option to Farm-in Agreement:

Under the terms of the HoA, NCM will have the right to acquire, in multiple stages, up to 75% of the Gorbea Project by completing a series of exploration and development milestones and making staged option payments to Mirasol.  NCM has committed to spend a minimum of US$4 million and complete a minimum of 3,000 m of drilling over an initial 18-month period, subject to drill permitting timelines. NCM has assembled a Chilean based exploration team with significant HSE exploration experience and will operate the Gorbea exploration program.

Stephen Nano, CEO of Mirasol, stated that “we are pleased to again be partnering with the Newcrest team to explore some of our prospective Mio-Pliocene belt projects for district scale gold deposits.  Newcrest has allocated a combined US$7.3 million in separate agreements, for the exploration of Mirasol’s Gorbea and Altazor projects over the next 12 to 18 months.  We are working with Newcrest to advance the permitting process for the Atlas project in the Gorbea package, with the objective of drilling during the southern hemisphere summer.”


Option phase:

  • A US$100,000 cash payment upon signing the Agreement;
  • NCM has a minimum commitment to spend US$4 million and drill minimum of 3000m in the first 18-month exploration program;
  • NCM will operate the project and will receive a 5% management fee; and
  • At the end of the option phase, NCM will have the right to exercise the farm-in phase of the Agreement.

Farm-in phase:

  • Stage 1: If NCM elects to exercise the option to farm-in, NCM will make a cash payment to Mirasol of US$500,000, and will have the right to earn 51% of the Project over a 4.5-year period (total 6 years) by spending an additional US$15 million (total US$19 million), which includes a minimum drilling commitment of 6,000 m on the Project to be completed within the first 2 years;
  • Stage 2: If NCM elects to proceed to Stage 2 of the farm-in, it will make a cash payment to Mirasol of US$650,000 and have the right to earn 65% of the Project over an additional 1-year period (total 7 years), by funding the delivery of a positive preliminary economic assessment, in accordance with NI 43-101 on a resource of not less than 1,000,000 ounces of gold at a cut-off grade of 0.30 grams per tonne (g/t);
  • Stage 3: If NCM elects to proceed to Stage 3 of the farm-in, it will have the right to earn 75% of the Project over an additional 2-year period (total 9 years) by funding the lesser of either: (i) additional expenditures after the completion of Stage 2 of US$100 million; or (ii) the delivery of a positive bankable[1] Feasibility Study, in accordance with NI 43-101;
  • Stage 4: After completion of Stage 3, Mirasol can elect to: (i) contribute its proportionate share (25%) of further development expenditures, (ii) exercise a one-time equity conversion option to convert up to 10% of its equity into a NSR royalty at a rate of 2.5% equity per 0.5% NSR royalty (max 2% NSR royalty) and then contribute funding to advance the Company’s remaining project equity interest; or (iii) dilute.

The rate of dilution royalty for Mirasol (up to 2% and triggered upon dilution of its interest to 10%) will be adjusted based on the percentage royalty acquired as part of the equity conversion option. NCM will hold a 0.5% NSR buyback right at fair market value exercisable on the conversion royalty or the dilution royalty.

 After NCM has met the minimum commitment in the Option phase, NCM may terminate at any time without liability. In the event that NCM should complete Stage 1, but elect not to proceed to Stage 2, then NCM’s 51% interest shall be adjusted to a 49% interest. In the event that NCM completes Stage 2, but elects not to proceed to Stage 3, then NCM’s 65% interest shall be adjusted to a 60% interest and the parties may agree to halt further exploration or continue and contribute in proportion to their interests or be diluted.

The HoA also contains other customary terms including extension rights to increase the duration of each stage 1, 2 or 3 for cash payments to Mirasol and pre-emptive rights provisions should either party elect to sell its interest in the Project.

Early Termination of the Zeus Agreement:

The companies have also agreed to the early termination of the Zeus Option to Farm-in Agreement that was previously announced on February 26, 2018. Under the terms of the Zeus agreement, NCM had a minimum spend commitment of US$1.5 million in the first 18-month exploration program. The balance of the minimum commitment expenditures for Zeus that have not yet been incurred, will be applied towards the $4 million initial commitment for the Gorbea Project. NCM has also agreed to a US$200,000 early termination payment to Mirasol. Upon termination, NCM will have no retained rights in the Zeus project.

Mirasol wishes to thank NCM for its investment that has advanced exploration of the Zeus project.  Mirasol will report the exploration results from last season’s Zeus exploration program shortly. Mirasol has initiated the business development process to identify a new joint venture partner to continue exploration at the Zeus project during the 2019 southern hemisphere summer season. Mirasol maintains the view that Zeus is a prospective, underexplored, Au+Ag project located in prospective geological setting, 43km East of the Goldfields Salares Norte HSE project[2] (of 3.7 Moz Au at 4.89 g/t Au and 49.5 Moz Ag contained within 23.3 Mt) in the Mio-Pliocene belt of Northern Chile.

Under the terms of the pervious Gorbea Joint Venture (terminated in April 2018), all exploration was managed by the then joint venture partner. Pre-joint venture exploration on the projects was managed by Stephen C. Nano, who is the Qualified Person under NI 43-101.  Exploration data generated from the previous Gorbea Joint Venture program was reviewed and validated by Mirasol prior to release. The technical interpretations presented here are those of Mirasol Resources Ltd.

Mirasol applies industry standard exploration sampling methodologies and techniques.

Assay results from surface rock, channel, trench, and drill core samples may be higher, lower or similar to results obtained from surface samples due to surficial oxidation and enrichment processes or due to natural geological grade variations in the primary mineralization.
