MIRANDA GOLD SIGNS OPTION AGREEMENT
ON ADVANCED GOLD-COPPER PROJECT IN COLOMBIA
Vancouver, BC, Canada – June 18, 2018 – Miranda Gold Corp. (“Miranda”) (TSX-V:
MAD) is very pleased to announce it has signed an option agreement on the Cauca project
- an advanced gold-copper project in the Miocene-age mineral belt of southern Colombia.
The Cauca project is in the Cauca department, 47km south of the department capital
Popayan - in the Almaguer Mining District - and consists of one title and one application, for
a total land area of 1,808 hectares. The Miocene Mineral Belt containing Cauca extends
from Colombia into Ecuador, and is characterized by numerous well -known districts and
discoveries including Solgold’s Cascabel Project less than 40km from the Colombia border.
Cauca is within one of the least explored terrains in Colombia. Cauca will join Miranda’s
Mallama Project for our second project in this important region.
The agreement is between Miranda and Carboandes, a private Colombian coal producer
active in the central Andes. Carboandes drilled a significant gold-copper-silver deposit
called “La Custodia” on the Cauca project in 2010.
Drilling in La Custodia and other targets (62 core holes for 22,047m total) on the project
shows gold-copper porphyry mineralization with a persistent overprint of epithermal gold
and carbonate-gold-base metal veins. Carboandes produced an internal resource estimate
from the La Custodia deposit of 700,000 ounces at 0.66 g Au/t ; but Miranda believes
vertical epithermal veins are significantly under-sampled by wide-spaced drilling, and a
more accurate representation of higher-grade veins in the deposit may provide a higher
estimated resource grade.
Of particular interest to Miranda in the La Custodia deposit, are local intercepts containing
epithermal mineralization that range from 2m at 28.4 g Au/t (2 g Ag/t) up to 2m at 1,095 g
Au/t (257g Ag/t) supe rposed on lower-grade porphyry-style veinlets. Miranda has
determined that core intercepts over 1 g Au/t consistently show high-angle epithermal veins
sub-parallel to core, cross-cutting porphyry-style veins. It is likely that numerous untested
veins or vein extensions occur between the current drill-holes that are spaced at an
average of 100m to 200m.
Important “takeaways” for the Cauca acquisition are:
• The Cauca project exposes Miranda shareholders to a potential quality deposit with
excellent upside potential.
• Of particular interest is that the orientation and distribution of epithermal related
mineralization has not been defined and modeled. Thus, it is likely that significant
Page 2
higher-grade epithermal mineralization is under-represented in previous drilling and
the historical resource estimate. Miranda believes most existing drill holes, on 100m
to 200m centers whether vertical or angled are sub-parallel to the trend of high-
angle veins. Miranda recognizes that higher values in drilling consistently correlate
with epithermal veins subparallel to core. To estimate grades in the deposit, and for
property-wide exploration, it is critical to determine vein trends and density and then
drill angle holes perpendicular to veins on a tighter spacing.
• Miranda has a path to a 100% interest in the property in the option agreement and
can advance the project on our own or with a joint venture funding partner at the
appropriate stage of advancement.
• Carboandes has done extensive baseline corporate social license work with local
stakeholders, and that advance work will aid the project’s advancement for Miranda.
The project has received permits in the past for large -scale drill programs, and
construction of support facilities, and it is likely these permits can be re-opened in a
timely fashion.
• Grid sampling shows extensive untested soil anomalies within the project, similar to
those occurring over the La Custodia drill-indicated mineralization. Rock samples
indicate undrilled epithermal veins in several areas. It is expected that expanded
exploration will show significant mineralization away from La Custodia
• The first-year Miranda expenditure obligation is modest and will be designed to
provide “Proof of Concept” that higher grade epithermal associated gold is
significantly under-sampled by the current drill-hole orientation and spacing. Early
Miranda exploration programs will prioritize close -spaced trenching to resolve
epithermal vein distribution and geometry, followed up by close -spaced angle-
drilling to create a three dimensional geology and grade model.
• Miranda believes that our early drilling results, combined with Carboandes’ existing
drilling in the La Custodia target zone will allow Miranda to produce a “Maiden” NI
43-101 Resource Report as early as 2019.
Project details:
Structural controls and porphyry-emplacement are related to fault and fracture systems of
the Cauca-Romeral Mega-structure or Suture zone. The predominant lithologies are
continental sediments intruded by hypabyssal diorite and quartz-diorite porphyry. Alteration
is external propylitic to phyllic to internal potassic in the core of the intrusives. Epithermal
veins trend predominantly northwest and secondarily northeast and have phyllic and
potassic selvages. The La Custodia is a gold-copper porphyry deposit with a persistent
low-sulfidation epithermal overprint, including gold -silver quartz veins, veinlets and
stockwork, and quartz-carbonate veins with base metals and gold.
The epithermal mineralization shows classic dark ginguro texture and abundant fine-to-
coarse free gold. Fluid inclusion studies show temperatures of vein formation at 400 to
500°C for Type A and Type B porphyry -style veins, and 150°C for epithermal veins,
indicating specific stages for vein formation. Porphyry mineralization was probably followed
by carbonate-gold-base metal veins, and then low-temperature gold - silver veins.
The project has several exploration targets. Exploration targets similar to La Custodia
include La Esperanza and El Limón - both with porphyry-gold-copper combined with
Page 3
epithermal-type mineralization. The Hueco Hondo prospect is 3.8km from La Custodia -
midway between La Custodia and La Esperanza – and is characterized by parallel
northwest-trending epithermal veins that show reconnaissance channel sample values up
to 127 g Au/t. The Hueco Hondo target is important in that it may illustrate the prevalent
orientation of veins on the project, including the orientation of potentially under-sampled
veins in La Custodia. Hueco Hondo consists of multiple parallel high-grade veins without a
porphyry component, further supporting a persistent epithermal overprint.
Several gold-arsenic soil anomalies occur across a significant part of the 1,808 hectare
property - but only two anomalies have been drilled to date. Drilling in one of these soil
anomalies resulted in the identification of the La Custodia deposit. Open soil anomalies
occur between La Custodia and Hueco Hondo, east of La Custodia, and north, south and
east of La Esperanza, which is seven kilometers north of La Custodia. Several high level
stream sediment anomalies have not been followed up with prospecting or soil grids.
Historic Internal Valuation Studies:
Carboandes discovered the La Custodia in 2010, and produced a project technical report.
They have conducted internal studies in support of resource estimations, preliminary
economic evaluations, metallurgy, and mining studies. The internal resource estimate of
the La Custodia - completed and internally reported in 2015 – provided a resource of
700,000 ounces gold at 0.66 g Au/t. Within this resource, using a plus-0.3 g Au/t cut-off, a
three-dimensional “grade-shell” was modeled and used for a trial pit optimization. Internal
to the pit, the gold-grade shell contains estimates of 307,450 ounces of gold, 1,323,000
ounces of silver, and 80,897,000 pounds of copper from a volume of 34 million tons of
mineralized material - at prices significantly below current prevailing prices. Additional plus-
0.3 g Au/t grade shells occur both below and adjacent to the pit shell. The vendor’s internal
metallurgical work shows a 95% gravimetric recovery of gold in the oxide zone and an 85%
recovery of gold; 80% recovery of copper; and 60% recovery of silver combining gravity
with flotation, in the sulfide zone.
The optimization utilized very preliminary assumptions for mining costs for an open-pit
blast, shovel, and truck operation with a production rate of 5,000 tons per day. A simple
inverse distance-squared isometric projection appropriate to generally uniformly distributed
mineralization, with cumulative frequency grade capping was used to model grades. The
optimization used metal prices of $1,254 per ounce gold, $15.80 ounce silver, and $2.05
per pound copper and recovery by gravimetric and conventional flotation milling.
Recoveries were estimated from multiple bench-scale and larger tests performed by
independent labs. The Carboandes internal report refers to all of its estimated resource as
“inferred” but this should be considered a general term and not completed in accordance
with CIM definitions of mineral resource categories.
No other resource estimates pre-date or post-date the 2015 estimate, and a qualified
person has not done enough work to verify or classify this historical resource estimate as
current mineral resources or reserves. Therefore, Miranda is not treating the information as
a current mineral resource or reserve. The internal work was conducted using professional
internal company standards and is considered reliable for its level of detail, but Miranda has
not independently reviewed and substantiated the work - Miranda is using the internal
Carbonandes work only to provide an estimate of exploration potential and as rationale to
continue exploration. An independent qualified person will need to perform their own grade
and resource modeling after additional drilling - and will do its own cost estimations and
Page 4
studies before preparing and filing an independent NI 43-101 technical report to support the
mineral resource. Most important will be an accurate measurement and projection of higher
grade epithermal-associated gold.
Importantly, Carboandes’ internal pit design is contained within a small area of only 14
hectares of the total 1,808 hectare project area. The project is near the Pan-American
Highway and secondary paved roads, the national power grid, and an airport. Topographic,
elevation, social, and environmental aspects of the Project are favorable for exploration and
development.
The Agreement provides Miranda a 60-day due diligence period before it becomes fully
effective. The due diligence will start immediately.
Work completed on the Cauca project is summarized in the following table:
La Custodia La Esperanza El Limon Total
Stream sediments 9 16 2 27
Soil samples 800 1,051 166 2,017
Rock chip samples 110 58 85 253
Channel samples 763 251 57 1,071
Thin-section samples 91 70 19 180
Pima samples 952 513 - 1,465
Core drilling samples 9,555 3,896 - 13,451
Screened Au samples 205 18 - 223
Cyanide leach samples 53 18 - 71
Significant drill intercepts are provided in the following table from the La Custodia deposit.
Only intercepts greater than 0.5 g Au/t are shown. Values over 1 g Au/t consistently show
some amount of epithermal quartz or quartz-carbonate veins, generally sub-parallel to core
and thus the veins are probably near vertical.
Miranda believes that closer-spaced, and properly angled holes with respect to the vein
trend, will better delineate the continuity and thickness of sub-vertical, higher gold grade
epithermal veins that we believe are presently under-sampled on a volume weighted basis
in the current La Custodia drill pattern and the La Custodia internal resource estimate.

U.S. investors are cautioned that mineral deposits on adjacent properties are not indicative of mineral deposits on our
properties. We advise U.S. investors that the SEC's mining guidelines strictly prohibit information of this type in documents
filed with the SEC.
This press release uses the terms “measured resources”, "indicated resources" and "inferred resources", which are estimated
in accordance with the Canadian National Instrument 43 -101 and the Canadian Institute of Mining and Metallurgy
Classification system. We advise investors that while those terms are recognized and required by Canadian regulations, the
U.S. Securities and Exchange Commission does not recognize them. U.S. investors are cautioned not to assume that any
part or all of mineral deposits in these categories will ever be converted into reserves. In addition, "Inferred resources" have a
great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be
assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian
rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in certain
exceptional cases. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is
economically or legally minable.
