Field Trial Preparatory Testwork at Steinert Perth Recovers Significant Gold From Previously Untested Fines Fraction
Novo Resources Corp.
”) (TSX-V: NVO; OTCQX: NSRPF) is
pleased to provide an update on advanced planning ahead of CY2021
field trials using its Steinert KSS mechanical sorter at the
Karratha Project (Comet Well and Purdy’s Reward). A highlight of
recent preparatory laboratory test work includes successful
recovery of significant gold from the previously untested fines
fraction (0-8mm) as well as recovery of fine gold encapsulated in
rocks from coarser size fractions (please see figure 1, figure 2,
figure 3, and figure 4 below). Both of these findings indicate
good potential for enhanced gold recovery utilizing mechanical
sorting and ability to treat finer crushed material. This implies
that mechanical sorting can potentially treat all crushed material
generated at Karratha.
Samples were excavated from sites across Purdy’s
Reward and Comet Well and transported to Steinert in Perth, WA.
1:500 scale high resolution mapping was undertaken by Novo
geologists prior to excavation of 2 x approximately 5t samples to
carefully pinpoint the mineralized target horizon contacts, with
the samples being crushed and screened into three size fractions:
0-8mm, 8-25mm and 25-75mm. Mineralization at the Karratha Project
is characterized by ‘melon seed’ nuggets, ranging from around
5-10mm, encased amid a chloritic halo of fine gold. Very little
evidence exists for fine gold outside of this halo.
Testwork is designed to:
- Refine sorter settings ahead of field
testwork on site at the Karratha Project commencing March / April
- Test the ability of the sorter to
detect and eject gold bearing material from the fines fraction
(-8mm) and, in particular, to test whether halo gold can be sorted
separate from the base nugget. This has proved successful.
- Provide qualitative assessment of fine
gold ejected from each sample.
- Confirm likely quantities of
concentrates to expect during field trials to help define plans for
extracting gold from sorting concentrates.
CY 2021 Field
Testwork is being designed
- Confirm recovery of gold from the
various size fractions discussed above via mechanical sorting.
- Determine the productive capacity of
sorting at each size fraction and analyze the relationship between
productivity and gold recovery.
- Provide information to support future
mineralization reports / resource work ahead of progressing towards
a full scale mining operation.
planning steps ahead of field
testing in 2021 are as
- Ngarluma Aboriginal Corporation must
provide consent for Novo’s plans. Importantly, this consent has
recently been granted.
- The environmental approvals process
has commenced with both the Department of Mines, Industry
Regulation and Safety (“DMIRS”) and the Department
of Water and Environmental Regulation (“DWER”).
Novo anticipates obtaining said approvals during Q1 2021.
- Identifying preferred bulk sample test
sites: high resolution mapping has identified 22 preferred sample
sites, with each site typically involving 3 panels of 10m x 10m x
1.5m of the targeted horizon (around 1,000t per sample
- Further drill testing of each
excavation site is planned to accurately confirm target horizons
and assess drilling and blasting requirements at each
- Sorter arrival and pre-commissioning
works° The Steinert KSS sorter has been built and is expected
to arrive in Perth WA as originally scheduled in late November
2020. The sorter and associated infrastructure will then be
pre-assembled at OPS Crushing in Perth ahead of transportation to
- Supporting services and
equipment° Crushing and screening contractor:
preliminary quotes received.° Feed conveyor, discharge
conveyors, accepts kibble, rejects stacker conveyor have been sized
and identified.° Cyclone proofed integrated site offices
and dome cover shelter have been designed and are under
construction.° Ancillary support: compressors and power
generation have been sized and identified.
- Earthmoving contractor will be engaged
closer to the trial date.
- Timing: testing is expected to
commence around March / April 2021° Timing dependent on
outstanding DMIRS and DWER approvals.° Avoidance of the
wet December-March season reduces the likelihood of unplanned
downtime from site evacuation due to cyclonic activity, also
avoiding site security and sampling integrity issues during
evacuation.° Road closures due to wet weather can
prevent gold bearing concentrates from being transported to
Nullagine.° Personnel required for the Karratha project
will be fully engaged in preparatory works associated with
advancement towards production at Nullagine in Q1, 2021.
Concentrate assessment / sorter testing:
- Previous testwork indicated that less than 3% of material
reports to concentrate – this was confirmed in the current test
work, and importantly, this mass pull holds true for the fines
fraction. Note that previous test work at Tomra in late 2018
(please see the Company’s news releases dated November 19, 2018,
December 20, 2018, and January 31, 2019) did not include the finest
- Gaining an expectation of the percentage of material pulled
into concentrate is important for future planning of concentrate
- With the acquisition of the Golden Eagle Plant at Nullagine,
Novo now has options to process concentrate to accurately determine
gold content and recover gold from Karratha trial concentrates
utilizing various components of the Golden Eagle mill circuit.
Novo CEO and Director, Mr Rob Humphryson
commented, “These test results have confirmed our understanding of
how sorting can be applied to the Karratha Project. A great deal of
planning has gone into ensuring the success of the field trials in
2021, with input from a wide cross section of the Novo team who are
at the forefront of the art of applying sorting technology to the
Company’s unique gold deposits. Importantly, our recently appointed
Project Metallurgist, Mr. Jason Aleknavicius gained operational
sorting exposure during this trial to build expertise ahead of
