Nova Minerals Announces Drilling to Commence at the Estelle Gold Project, Alaska, and Company Update
July 31 2024 - 5:45AM
Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA,
NVAWW) (ASX: NVA) (OTC: NVAAF) (FSE: QM3) is pleased to announce
the commencement of resource definition drilling and exploration
field programs on its over 200mi2 flagship Estelle Gold Project,
located in the prolific Tintina Gold Belt in Alaska.
The Company is focused on Feasibility Study (FS)
stage drilling at the high-grade RPM deposit to continue to
increase and prove-up resources to the higher confidence Measured
and Indicated categories. With a total defined 5.2 Moz Au in-pit
constrained S-K 1300 compliant resource (Table 1) across 4
deposits, the Estelle Gold Project has development optionality in
terms of initial project size and scale, which is subject to market
conditions and strategic partners to meet our objective of
ultimately growing the Estelle Gold Project into a tier 1 gold
producer. The Feasibility Study currently underway is considering a
strategy to achieve production with a scalable operation, by:
1. |
Establishing an initial low capex smaller scale operation
at the high-grade RPM deposit requiring less infrastructure for
expected early cashflow and high margins to potentially self-fund
expansion plans; and/or |
|
|
2. |
Develop the higher capex larger mining operation for
increased gold production, cash flow, and mine life that potential
future large gold company strategic partners have expressed an
interest. |
|
|
Work Plan and PFS
Highlights:
● |
Resource Drilling. Program focused at RPM to increase and prove-up
resources as part of the Feasibility Study utilizing the company
owned drill rig to achieve a cost efficient program (Figures 1 to
5). |
|
|
● |
Mineral Resource Estimate (MRE). Update to include the 2023 and
2024 drilling data and to incorporate the higher gold price for an
updated resource. |
|
|
● |
LIDAR. Detailed survey across the property to enable detailed
infrastructure design, mineral reserve classification, exploration,
etc. |
|
|
● |
Heap Leach. Metallurgical test work is currently underway with METS
Engineering to include a low-cost gold recovery method option in
the flow sheet for processing lower grade ores to potentially
substantially reduce capex and increase the gold production
profile. |
|
|
● |
Geotechnical. Detailed studies are underway to potentially increase
pit slope angles further. Early indications show very competent
geology, with the study results expected to have a significant
positive impact on the project economics. |
|
|
● |
Ore Sorting. FS level test work to commence to investigate the
additional benefit of using Steinart multiple sensor technologies
and further improve on previous exceptional results from utilizing
XRT density sorting. Ore sorting results to date have shown the
potential to significantly improve resource extraction providing
processing optionality, which is expected to reduce overall
processing costs, increase total gold production, and increase the
life of mine. In addition, planning is underway to complete a
future 200kt bulk pit pilot test program to further de-risk ore
sorting and optimize material handling and flow. The expected
benefits of ore sorting to improve project economics include: |
|
○ |
Pre-concentration of mill feed by separating it into high-grade,
low-grade and waste fractions |
|
|
|
|
○ |
Selective high grading of lower grade ores and existing waste
dumps |
|
|
|
|
○ |
Reduction of environmental risks and costs – smaller tailings dam
footprint |
|
|
|
|
○ |
Optimization of multiple process streams, for example, sending
appropriate ore to the mill and heap leach |
|
|
|
|
○ |
Pre-concentration of ore in order to reduce transportation
costs |
|
|
|
|
○ |
Lowering operating costs |
|
|
|
|
○ |
Improving ore grade |
● |
Critical Elements. In addition to copper and silver, highly
elevated concentrations of Antimony and other critical elements
have been discovered at numerous prospects across the Estelle
Project. These elements have the potential to provide significant
by-product credits to the project. The Company continues to include
multi-element analysis for all samples to define these resources
for potential future extraction from the gold processing waste
stream, and/or as a stand-alone small-scale operation for near term
cash flow, i.e. for antimony production which is found in prospects
outside of the existing gold deposits. The Company continues to
pursue this opportunity as well as federal and state grants for
critical minerals development studies and extraction/refining plant
capital requirements. The US Government is engaged in providing
grant funding and support through the Defense Production Act (DPA)
and other legislation to establish and fully secure US domestic
critical minerals supply chains which are currently controlled by
foreign adversaries. The Estelle Gold Project with its potential of
contained critical mineral resources and other key project aspects
could contribute to achieving these US national security
objectives. |

Nova CEO, Mr Christopher Gerteisen
commented: “In less than 5 years we have taken the project
from green fields to a total 5.2 Moz Au in-pit constrained S-K 1300
compliant resource with a FS now in progress. We have focused
defining high confidence resources for conversion to reserves at 2
deposits, RPM and Korbel, from the over 20 prospects across the
Estelle Gold Project on our path towards production. Now in the FS
stage, the asset is progressing towards development with our
strategy reflecting the flexibility of the project to current
market conditions and our commitment to balance sheet management,
with a low-capex, expected high margin, scalable start-up operation
with potential self-funded expansion and/or a strategic partner to
advance the full-scale production scenario to ultimately realize
our goal of becoming a tier 1 gold producer with the Estelle Gold
Project.”
This strategy provides a defined path to
production designed to provide free cashflow, while potentially
allowing us to continue to unlock the district organically and to
deliver on our prior track record of resource growth, new
discoveries, at a low-cost per discovery ounce.”
2024 RPM Drill Plan
Highly targeted and strategic drilling at the
RPM deposit continues, with the Company owned Reverse Circulation
(RC) rig working to upgrade and expand the current resource. Of the
drilling planned for 2024, the majority will be allocated to
advance the RPM high grade starter pit area and to further
delineate the at-surface, high-grade (1 g/t Au to > 5 g/t Au)
zone encountered there during 2022-2023 drilling, while upgrading
inferred resources and testing for potential near surface
extensions of the high-grade gold system to the south and west
(Figures 1 to 5). Drilling at RPM will be complemented by ongoing
metallurgical work and environmental surveys as outlined in this
announcement along with studies as necessary to inform economic
assessment of the discovery to gain a head start for a potential
initial low capex smaller scale operation at the high-grade RPM
deposit requiring less infrastructure for early cashflow and high
margins to self-fund expansion plans.
Due to the speed, efficiency and lower costs of
running the Company owned RC rig on labor hire only, when compared
to diamond drilling, this drill program is designed to be conducted
at a lower cost, while providing the necessary data density to meet
our objectives of expanding and proving up a significant amount of
the existing RPM resource into the Measured and Indicated
categories to allow conversion into economic reserves for the
upcoming FS.
The Company looks forward to announcing the
assay results from the drill campaign as they come in to assess the
significance of the observations in Figures 1-4.
