April 30 , 2018 - Discovery Metals Corp. (TSX-V: DSV) ("Discovery" or the "Company") is
pleased to announce the first batch of assays results from the detailed continuous underground
channel sampling program at its flagship Puerto Rico project (“Puerto Rico” or “the Project”) in
northern Coahuila State, Mexico. Results of the first 100 samples are presented in this release
and are from the Zaragoza mine , one of th ree key historic mines on the Project. Results from
the San Jose mine and Puerto Rico mine will be presented as results are received.
Taj Singh, P.Eng, President & CEO stated, “ First assay r esults from the sampling program at
Puerto Rico validate our thesis that there is a significant amount of mineralization remaining in
and around the historic underground workings. The results also indicate impressive continuity of
the mineralization over the entire area of workings assayed to date. For the next three months
our focus will be to continue to systemically map and sample Puerto Rico. We will have a

refined geological model for the Project and a substantial number of high- priority drill targets
ahead of our anticipated drilling program in Q3. In addition to the exploration program at Puerto
Rico, the detailed mapping and sampling programs at the Minerva and Monclova projects are
progressing on schedule with first assay results expected shortly.”
Results & Discussion:
The 100 channel samples released herein are all taken from the Zaragoza mine, easily
accessible via a surface adit. Based on Discovery’s recent work, Zaragoza is estimated to
contain approximately 330m of developed underground drifts and stopes over three levels,
known as the Chica, Grande, and Lower levels . The underground w orkings cover an
approximate strike and width of 100m and 80m respectively, and appear to be open in all
directions for further exploration.
Channel samples were collected at intervals every 3m to 5m along both sides of the entire
length of the developed workings. Of the 100 channel samples reported herein, 79 samples are
part of 38 “composite channels” which comprise 2 to 3 side-by-side individual channel samples;
the remaining 21 channel samples are individual channels. The first batch of assay result s
from these 100 channel samples represents approximately 128m of development. Channels
were chip-cut perpendicular to mineralization, i.e. vertically to cross flat -lying manto structures
and horizontally to cross chimney structures . Sampling locations and widths were restricted to
the extent of historic workings . The table below highlights assay results of 20 of the most
significant individual channel assays (uncomposited):

Mineralization in the workings at Zaragoza is dominated by zinc, lead and copper oxides and
sulphides, frequently with associated Ag, contained in mantos and also in fault-breccia hosted
chimneys. The relative mix of oxides and sulphides has not yet been determined. Based on
current sampling results, manto mineralization over the Chica and Grande levels of Zaragoza
has an average grade of 157 g/t Ag, 6.2% Zn, 5.5%Pb, and 0.1% Cu (arithmetic mean of
Page 2 of 4
assays from all channels taken on manto mineralization) . Mineralization continues into the
limestone wallrock, with higher grades along hanging wall (HW) / footwall (FW) contacts. Iron
oxide alteration as well as the presence of abundant calcite and barite veining are the
predominant styles of alteration seen in the wallrock. Results from composite channels, oriented
to cross m ineralization and the associated HW and/or FW, demonstrate strong grades over
larger widths vs. individual mantos , chimneys or breccias . The table below shows assays from

The distribution of mineralization and structural characteristics across the levels at Zaragosa
demonstrates the continuity and significant potential size of the mineralized zones on the Puerto
Rico project. Discovery will continue its underground mapping and sampling programs to
advance and target the complex interplay of regional and localized faulting, stratigraphic
controls, and intrusive interaction on hydrothermal fluid transport that affect the development of
high grade zones of mineralization.

About Puerto Rico: The Puerto R ico p roject is a large, multi -target carbonate replacement
(CRD) silver-zinc-lead mining district that has historically produced approximately one million
tonnes of shallow, high- grade, direct-shipping ore. There has been no modern exploration or
drilling carried out at Puerto Rico. Discovery Metals controls approximately 350 square- km of
mineral rights covering a 6km long trend of historic mines with hydrothermal alteration, as well
as prospective structural extensions of known mineralization on the Puerto Rico project.
Sample analysis and QA/QC Program: The rock chip channel samples presented herein were
all cut perpendicular to mineralization and had minim um width and depth of 60mm and 30mm
respectively. The entire mass of each of the channel samples was transported and prepared at
the ALS lab facilities in Zacatecas and Chihuahua facilities; here, samples were dried, crushed,
split and pulverized, then shipped to the ALS lab in Vancouver. At ALS Vancouver, sampl es
were analysed for: (1) gold, using a standard fire assay with a 30- gram pulp and Atomic
Absorption (AA) finish for gold; (2) multi-element analyses, using inductively coupled plasma
atomic emission spectrometry (ICP-AES). For overlimits, samples were reassayed as such: (1)
for values of zinc > 10%, values of lead > 10%, and values of silver > 100 g/t, samples were re -
assayed using the ME -OG62 (high-grade material ICP -AES) analytical package; (2) for values
of zinc or lead greater than 30%, samples were re- assayed using the Zn- VOL50 or Pb-VOL50
Page 3 of 4
(potentiometric titration) analytical methods, respectively; (3) for values of silver greater than
1,500 g/t, samples were re- assayed using the Ag -CON01 analytical method, a standard fire
assay with 30g pulp and gravimetric finish. Certified standards and blanks were routinely
inserted into all sample shipments to ensure integrity of the assay process.

ABOUT DISCOVERY METALS
Discovery Metals is focused on discovering and advancing high grade polymetallic deposits in a
recently assembled land package of approximately 300,000 hectares over a large and historic
mining district in northern Coahuila State, Mexico. The portfolio of seven key properties, all with
shallow high -grade silver -zinc-lead mineralization, is situated in a world class carbonate
replacement belt that stretches from southeast Arizona to central Mexico. The land holdings
contain numerous historical dir ect-ship ore workings with ~4km of underground development.
No modern exploration or exploration drill testing has been carried out on the properties.
