Mandalay Resources provides production and cost guidance for 2020, with significant organic production growth expected at Costerfield. At Costerfield, the high-grade Youle vein is ramping up and will continue to increase production through 2020 and into 2021. At Björkdal, production is steadily ramping up from the new Aurora zone as more underground levels are developed and stoping is increased. Mandalay also secured a $65 million credit facility to provide financial flexibility and long term balance sheet management.

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.

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

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

2019:
• Began deep hole
program with first

2020:
• Second deep hole

DEEP DRILLING AT COSTERFIELD
DRILLING PROGRAM ADVANCING STRATIGRAPHY KNOWLEDGE OF THE COSTERFIELD DISTRICT
• First deep drill hole: CD001 completed
at 1,700 m with a wedge hole
(CD001W1) covering ground above the
initial hole targeting an inferred
anticline to the east.
• The predicted anticline was found to be
in a truncated state exhibiting
pervasive alteration and some quartz
stockwork veining.
• Whilst interpreted to be the feeder
zone for fluids enriching Youle veining,
the altered zone was not itself
enriched.
• This information has been incorporated
into the deeps targeting geological
model for definition of the next hole.
• CD002 commenced in March 2020
targeting the same fluid corridor under
Cuffley.
