De Grey Reaches A$7M Minimum Spend at Egina Gold Project and Continues
Investment
HIGHLIGHTS
• At the Egina Gold Project, De Grey Mining (ASX: DEG) has continued an aggressive exploration program at the Becher
Project, with drilling at Heckmair, Irvine, Lowe and Whillans Prospects. Egina is located southwest of, and in close
proximity to, De Grey’s 12.7 Moz Hemi Gold Project.1
• Novo’s Egina tenements are considered by De Grey and Novo to be highly prospective for significant intrusion-related
gold deposits and share similar attributes to the Hemi deposit.
• In addition to Novo’s approx. 60,000 m AC and RC drilling completed in 2023, De Grey has completed 34,180 m of AC
drilling and 9,129 m of RC drilling to date across the four main prospects, testing prospective intrusions and regional
structures, as well as a drone magnetic survey.
• Anomalous gold results2 during the initial expenditure period include:
• 6m @ 1.2g/t Au in MSRC0068 at Heckmair;
• 4m @ 2.1g/t Au in MSAC0989 at Irvine;
• 8m @ 4.7g/t Au in MSRC0031 at Lowe.3
• De Grey has now satisfied its initial A$7 million minimum expenditure commitment over a 15-month period on
exploration at the Egina Gold Project.
• De Grey now has the right to earn a 50% joint venture interest in the Egina tenements by spending an additional A$18
million through to June 30, 2027, at which time a Joint Venture will be formed with customary funding and dilution rights
applied to both De Grey and Novo.
• The combined Egina Gold Project and De Grey’s tenure forms a strategically significant land position in the Mallina
Basin covering approximately 2,500 sq km.
• Forward programs by De Grey in 2024 will include follow-up targeted RC and diamond drilling.

VANCOUVER, British Columbia, Oct. 09, 2024 -- Novo Resources Corp. (Novo or the Company) (ASX: NVO) (TSX: NVO)
(OTCQX: NSRPF) is pleased to provide a progress update on exploration activities at the Egina Gold Project (Figure 1) with De
Grey Mining Ltd (De Grey) (ASX:DEG).
Novo Executive Co-Chairman and Acting CEO Mike Spreadborough said: “ We are delighted that De Grey shares our
enthusiasm for the Egina Gold Project. We’ve been exploring the Mallina Basin since 2017, attracted by its gold prospectivity.
To be able to partner with a group like De Grey, with its nearby Hemi deposit, provides the best opportunity for us to drive
value for our shareholders at Egina, through any potential new discoveries and future exploration success.”
“Importantly, De Grey is just starting to explore at Egina, with several highly prospective areas yet to be systematically tested,
providing multiple new targets to explore and build upon the platform set by De Grey over the past 12 months.”
“Meanwhile, we remain focussed on progressing our prospects in the Pilbara and Victoria, as well as assessing project
generation opportunities.”
De Grey General Manager Exploration, Phil Tornatora, commented: “The Egina Project is an important part of De Grey’s
strategy to grow a large regional scale resource base around the planned Hemi processing plant. The Egina tenements are
approximately 1,000 sq km and significantly grows the land position De Grey has exposure to around Hemi. Egina contains
major structures and geological units which extend from Hemi and is prospective for both large intrusion-hosted deposits like
Hemi and orogenic gold deposits. Large prospective areas of the Egina Project have not been explored so we believe the area
still has exciting potential.
“During the September quarter, De Grey satisfied its minimum expenditure commitment by spending A$7 million over a 15-
month period. Our intention is to continue to progress exploration on the Egina tenements towards forming a 50:50 joint
venture subject to ongoing assessment of exploration results on the Project.”

In June 2023, Novo entered into an earn-in and joint venture agreement with De Grey for the Company’s Becher Project and
adjacent tenements within the Egina Gold Camp (Figure 1), with the resultant joint venture to be known as the Egina JV.
De Grey is earning into the Egina JV and has advised Novo that it has now satisfied the initial minimum expenditure
requirement of A$7 million (required prior to December 2024). This is part of a required A$25 million spend within 4 years to
earn 50% of the joint venture. The combined Egina JV and De Grey tenure forms a strategically significant land position in the
Mallina Basin covering approximately 2,500 sq km.
De Grey assumed management control of the Novo area (under the earn-in arrangements) from 1 July 2023 and rapidly
advanced key exploration efforts through targeted AC and RC drill programs and geophysical surveys.
The Egina JV tenure comprises a large 1,034 sq km tenement package adjacent to De Grey’s existing Hemi Gold Project
(‘Hemi’) and is located immediately south of Withnell and southwest of the Hemi deposits (see Figure 2).

Egina Gold Project Prospectivity
Egina contains similar geology and structures to those found within Hemi, in some cases directly along strike from De Grey’s
current exploration areas. Consolidating exploration of the Egina tenements with Hemi is an important step in De Grey’s
strategy to discover and grow a large resource base centred around the future Hemi processing plant.
Previous exploration by De Grey within the existing Farno Joint Venture (De Grey 75% and Novo 25%) and recent drilling at
the neighbouring Becher and surrounding prospects (contained within the Egina Project area) highlight the potential for the
discovery of large scale, intrusion-related gold deposits similar to Hemi, as well as shear-hosted orogenic deposits similar to
the Withnell and Mallina deposits.
The additional tenure in the west of Egina also contains strike extensions of the structural corridor that hosts the Mallina
deposit and opportunities to discover new intrusions similar to Toweranna and Charity Well.
As part of the A$7 million minimum expenditure requirement, De Grey has completed 34,180m of aircore drilling and 9,129 m
of RC drilling in 2024 across four main prospects testing prospective intrusions and regional structures (Figure 3). A drone
aeromagnetic survey was also completed in the Becher area.
Most of the remaining areas throughout Egina have received very little modern systematic exploration, providing scope for new
discoveries.
Figure 3 Egina anomalous gold intercepts and drilling (see Appendix: Tables 1 and 2).
Previous results from De Grey’s work on the Egina Project were provided by De Grey in an ASX release on 13 February 2024
(Greater Hemi and Regional Exploration Update), and by Novo in its ASX release on 14 February 2024 (Significant Drill Results
at Becher corrected), which included a best intercept of 8m @ 4.7 g/t Au from 97 m in MSRC0031 at the Lowe prospect, with
mineralisation associated with a deformed intrusive sill.
Other highlights included a large WNW-trending 1.5km brittle fault zone in the Heckmair intrusion with broad intervals of
anomalous base metals and low-level gold mineralisation. A follow-up RC program comprising 19 holes (2,368 m) returned
strong base metal values including 10 m @ 0.1g/t Au, 29.7 g/t Ag, 0.3% Cu, 1.5% Pb and 1.8% Zn in hole MSRC0016, and
24 m @ 0.2 g/t Au, 13.2 g/t Ag, 0.1% Cu, 1.0% Pb and 0.1% Zn in hole MSRC0017, with individual metres grading up to 4%
Zn and 4% Pb. The best gold intercept was 2m @ 2.8 g/t Au in hole MSRC0013 (See Novo’s ASX release dated 14 February
2024).
Prospect locations in the Becher area are shown in Figure 3, with significant intercepts given in Appendix: Tables 1-3.
Exploration since De Grey’s Greater Hemi and Regional Exploration Update on 13 February 2024 includes AC and RC drilling,
in addition to the drone aeromagnetic survey, which was flown to enable more detailed structural and geological interpretation
of bedrock.
Whillans Prospect
Multiple thin anomalous gold intercepts were returned at the Whillans prospect from drillholes MSRC0074, and MSRC0076,
associated with minor quartz veining and weak sericite alteration of metasedimentary arkosic sandstone and siltstone.
Heckmair Prospect
Multiple thin intercepts were returned at the southern edge of the Heckmair sanukitoid intrusion from drillholes MSRC0012,
MSRC0013, MSRC0068, MSRC0069, including 6 m @ 1.2g/t Au in MSRC0068, Novo ASX release on 14 February 2024
(Significant Drill Results at Becher corrected). All intercepts were associated with minor quartz veining and weak sericite
alteration and hosted within a dioritic intrusion.
Irvine and Heckmair East Prospects
Aircore drilling at Irvine, extending to the eastern side of the Heckmair Intrusion has identified broad zones of Zn-Pb-Ag and
gold anomalism within the weathered horizon. These are adjacent to the previously reported intercepts of base metal
mineralisation within the Heckmair Fault that bisects the Heckmair intrusion (Figures 4 and 5). In the Mallina basin, base
metal anomalies can signal enhanced gold prospectivity. Better gold intercepts include 12 m @ 0.8g/t Au (including 4 m @
2.1g/t Au) in MSAC0989. Gold mineralisation is hosted in quartz veining within metasediments, immediately adjacent to an
intrusion. Anomalous base metal intercepts include 25 m @ 0.99% Zn+Pb (MSAC0962) and 43 m @ 0.53% Zn+Pb
(MSAC0963).
Four metre composite samples with anomalous base and precious metals assays are currently being re-split and will be
submitted for multi-element and fire assay gold analysis, with ongoing interpretation and targeting to follow.

(see Appendix: Tables 2 and 3)
Figure 5 Section showing anomalous base metal (Zn+Pb) results in AC drilling at Heckmair East (see Appendix: Tables 2 and
3)
Four metre composite samples with anomalous base and precious metals assays are currently being re-split and will be
submitted for multi-element and fire assay analysis, with ongoing interpretation and targeting to follow.
Planned work
De Grey is currently awaiting final assay results including aircore re-splits. Work will continue compiling and analysing results
from recently completed work programs in addition to generating additional targets and developing follow-up programs.
Negotiations with the Mugarinya Community Association are continuing regarding an access agreement to the Yandeyarra
Aboriginal Reserve, which covers some of the Egina tenements. A high-level Aboriginal heritage area avoidance survey was
recently completed on tenements within the Yandeyarra Reserve with results pending. Discussions are also underway with the
Ngarluma Aboriginal Corporation regarding upcoming heritage surveys.
Once these permits and clearances are in place, De Grey will be well-positioned for exploring areas that have previously seen
little to no modern exploration.
On-ground exploration activities will progress from minimum impact, typical early-stage activities including ground gravity
surveys, surficial geochemical surveys, geological mapping including remote sensing methods. De Grey advises that it intends
to then progress to AC drilling for target generation and sub-surface geological mapping. Follow up target testing drilling would
then generally involve follow-up AC, RC and DD drilling.
Key terms of the Egina HOA between De Grey and Novo include:
• De Grey has the right to earn a 50% joint venture interest in the Novo tenements by spending a total of A$25 million
within four years from June 2023 (including the A$7 million already spent);
• De Grey has full program management and sole rights to explore the tenements during the earn-in phase;
• Upon De Grey earning a 50% interest, a joint venture (“Egina JV”) will be formed;
• De Grey will remain the manager of the Egina JV while it holds a minimum 50% interest; and
• Each party will be responsible for funding its share of joint venture costs or have its share of the joint venture subject to
dilution at a rate of 1% per A$1 million of non-expenditure contribution.
ANALYTICAL METHODOLOGY – AC DRILLING
AC drilling is utilised as a first pass technique testing for gold mineralisation and anomalous pathfinder geochemistry in
basement rocks under cover. The drilling methodology is rapid and low cost, with a low impact footprint, enabling large
systematic programs to be completed in a cost effective and timely manner.
One metre AC drill samples are collected from the drill rig through a cyclone and placed on the ground in piles for geological
quantitative and qualitative logging. These piles are then speared as four-meter composites.
All AC chip samples were sent to ALS in Perth, Western Australia and each sample was dried, split, crushed and pulverised
to 85% passing 75 µm. 11 elements assayed with aqua regia mass spectrometry (ALS Lab Code ME-MS43) with an
additional 29 elements assayed with aqua regia ICP-AES finish (ALS Lab Code ME-ICP43), and trace-level gold by 25 g aqua
regia (ICP-MS). All aircore holes end with a 1 m bottom of hole sample using the ME-MS61 method with Au by 30 g fire assay
(Au-ICP21). Anomalous aircore composites, greater than 0.1 ppm gold over 4 m, are re-split to 1 m samples and were
assayed using 30 g Au fire assay with ICP finish (ALS Lab Code, Au-ICP21) and high-grade results >10 ppm Au were assayed
by fire assay and gravimetric finish (ALS Lab Code Au-GRA21). Multielement analysis was conducted using four acid digest
followed by ICP-MS finish for 61 elements (ALS Lab Code ME-MS61™).
QAQC procedures for the program include insertion of certified coarse blanks (minimum rate 2%), certified standards (CRMs
minimum rate 2%), and routine duplicate sampling.
ANALYTICAL METHODOLOGY – RC DRILLING
RC drilling allows for deeper testing of anomalies delineated by aircore drilling, and other geological direct targeting methods
such as surface mapping and sampling, where bedrock is exposed at surface.
RC sampling utilized a cone splitter on the rig cyclone and drill cuttings were sampled on 1m intervals. All RC chip samples
were sent to ALS in Perth, Western Australia and each sample was dried, split, crushed and pulverised to 85% passing 75
µm. All RC drilling samples were assayed using 30 g Au fire assay with ICP finish (ALS Lab Code, Au-ICP21) and high-grade
results >10 ppm Au were assayed by fire assay and gravimetric finish (ALS Lab Code Au-GRA21). Multielement analysis was
conducted using four acid digest followed by ICP-MS finish for 61 elements (ALS Lab Code ME-MS61™).
QAQC procedures for the program include insertion of certified coarse blanks (minimum rate 2%), certified standards (CRMs
minimum rate 2%), and routine duplicate sampling.
There were no limitations to the verification process and all relevant data was verified by a qualified person as defined in
National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) by reviewing analytical procedures
undertaken by ALS.

(Criteria in this section apply to all succeeding sections.)
Criteria JORC Code explanation Commentary
Sampling
techniques • Nature and quality of sampling (e.g. cut
channels, random chips, or specific specialised
industry standard measurement tools appropriate
to the minerals under investigation, such as down
hole gamma sondes, or handheld XRF
instruments, etc.). These examples should not
be taken as limiting the broad meaning of
sampling.
• Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or systems
used.
• Aspects of the determination of mineralisation
that are Material to the Public Report.
• In cases where ‘industry standard’ work has been
done this would be relatively simple (e.g. ‘reverse
circulation drilling was used to obtain 1 m
samples from which 3 kg was pulverised to
produce a 30 g charge for fire assay’). In other
cases, more explanation may be required, such
as where there is coarse gold that has inherent
sampling problems. Unusual commodities or
mineralisation types (e.g. submarine nodules)
may warrant disclosure of detailed information.
• All drilling and sampling was undertaken in an
industry standard manner.
• RC holes were sampled on a 1m basis with
samples collected from a cone splitter mounted
on the drill rig cyclone. The 1m samples typically
ranged in weight from 2.5kg to 3.5kg.
• Aircore samples were collected by spear from
1m sample piles and composited over 4m
intervals. Samples for selected holes were
collected on a 1m basis by spear from 1m
sample piles. Sample weights ranges from
around 1kg to 3kg. Aircore results have not been
used in the resource estimate.
• Commercially prepared certified reference
material (“CRM”) and course blank was inserted
at a minimum rate of 2%.
• Field duplicates were selected on a routine basis
to verify the representivity of the sampling
methods.
• Sample preparation is completed at an
independent laboratory where samples are dried,
split, crushed and pulverized prior to analysis as
described below.
• Sample sizes are considered appropriate for the
material sampled.
• The samples are considered representative and
appropriate for this type of drilling. RC samples
are appropriate for use in the Mineral Resource
estimate.
Drilling
techniques • Drill type (e.g. core, reverse circulation, open-
hole hammer, rotary air blast, auger, Bangka,
sonic, etc.) and details (e.g. core diameter, triple
or standard tube, depth of diamond tails, face-
sampling bit or other type, whether core is
oriented and if so, by what method, etc.).
• Reverse Circulation (RC) holes were drilled with a
5 1/2-inch bit and face sampling hammer.
• Aircore holes were drilled with an 83mm diameter
blade bit.
