This presentation provides an overview of Mandalay Resources Corporation's portfolio and 2020 guidance. It summarizes that Mandalay has two producing assets, Costerfield and Björkdal, that offer organic production growth and exploration potential. Costerfield in particular is expected to see a major production uplift from ramping up mining of the high-grade Youle vein. Mandalay also recently secured a $65 million credit facility and has hedging programs in place to strengthen its balance sheet.

COVID-19 PANDEMIC AND MANAGEMENT CONTROLS
SAFE PRODUCTION AND SAFE WORKING CONDITIONS
Priority remains the health and safety of our employees, contractors and the communities in which we
operate. Our management teams have taken comprehensive measures to reinforce safe work procedures
and business continuity plans are in place with site-specific contingency considerations, should they be
needed. Mandalay will continue monitoring information from governments and health organizations.
The following protocols are in place at our operations:
• Surveyed workforce to identify at high-risk employees;
• Established clear policies for any workers displaying signs of illness. Employees or contractors cannot
come to work if displaying any symptoms;
• Intermittent on-site temperature checks;
• Where possible, employees to work from home, and flexible work arrangements are in place to reduce
contact between persons and maintain social distancing guidelines;
• Sites have reviewed hygiene and sanitization protocols and increased frequency in cleaning of common
and high-traffic zones. Additional hand washing stations installed;
• Implementing risk management processes for crew shift changes to ensure social distancing protocols
and reduction in movement of employees between crews; and
• Restricting visitors to essential visitors only.

THE YOULE LODE: DRIVING FUTURE SUCCESS
MAJOR PRODUCTION INCREASES EXPECTED FROM YOULE RAMP UP
• Youle vein lies within the North-South
trend also containing August and Cuffley
veins
• Drilling has allowed for a high-grade
reserve to be formed around Youle which
is still open to the North and at depth
• Currently developing on multiple levels
with first stoping commenced in late June
2020
• Extensional exploration 2020 has

DEEP DRILLING AT COSTERFIELD
FOSTERVILLE AND COSTERFIELD ARE FUNDAMENTALLY SIMILAR IN MINERAL SOURCE, FLUID
COMPOSITION, FLUID TRANSPORTATION SYSTEM AND FLUID TRAP ENVIRONMENT
Fosterville
Costerfield
30 km
Fosterville Deposits Costerfield Deposits
Could there be similar style gold mineralisation at Costerfield?
• Key similarities in the upper Costerfield system that Mandalay has mined
• A litho-geochemical (carbonaceous shales) environment exists, at depth, that is similar to the Fosterville
high-grade (Swan zone) environment
• Mandalay has intercepted mineralisation in the sub King Cobra drilling with 2 of 4 historical intercepts
returning high gold grades supporting the analogy

TARGETING A POTENTIALLY HIGH-GRADE ENVIRONMENT
DEEP HOLE DRILLING PROGRAM TO TEST FOR HIGH-GRADE MINERALIZATION AT DEPTH
2014:
• Previously
intersected a high-
grade mineralized
vein with two deep
holes drilled under
Cuffley vein
2019:
• Began deep hole
program with first
deep hole under
Youle vein
(completed)
2020:
• Second deep hole
under
Cuffley/Augusta
vein commenced in
late March 2020

DEEP DRILLING AT COSTERFIELD
DRILLING PROGRAM ADVANCING STRATIGRAPHY KNOWLEDGE OF THE COSTERFIELD DISTRICT
• First deep drill hole: CD001 completed
at 1,700 m
• New interpretation of the folding
suggests a likely structural setting
exists for a Costerfield size deposit
below Youle and above the fault
• Thick quartz blowout between 1,583 m
– 1,595 m:
o This wide interval of quartz
contained minor pyrite
mineralization and zones of sericite-
chlorite alteration
• Geological learnings from first hole
have been carried over to the deep hole
at Augusta / Cuffley which commenced
in late March 2020

COSTERFIELD REGIONAL TESTING
EARLY SUCCESS OF THE BROWN’S PROSPECT DRILLING PROGRAM
Brown’s drilling program still underway:
• Two out of five holes completed (total of
623 m has been drilled of the 1,200 m
program)
• First drill hole intercepted 14.51 g/t Au,
over 1.27 m (true width) in diamond drill
hole BWN001
• BWN001 & BWN002 were drilled below
the historic Felix Brown mine

AURORA ZONE STEERING UNDERGROUND RAMP UP
AURORA ZONE PROVIDES THE POTENTIAL TO MINE HIGH-TONNAGE AND HIGHER-GRADES MORE
COST EFFECTIVELY
• Aurora zone significantly wider and
consistently higher-grade than current mill
feed
• Currently known mineralization over 500 m
horizontally and 400 m vertically
• Aurora zone readily accessible; six levels
currently being developed
• Large step-out drilling occurring below and
East and West of currently known
mineralization
• Preliminary processing results show no
