Corazon Mining Limited (ASX: CZN) (Corazon or Company) is pleased to announce highgrade lithium assay results from spodumene-bearing pegmatite within the Miriam Nickel Sulphide Project (Miriam or Project) in the Eastern Goldfields region of Western Australia (Figure 2).
Corazon recently reported the discovery of spodumene (lithium mineral) bearing pegmatite along with widespread indicators of pegmatite in a field-mapping program undertaken at the Miriam Project. The identification of spodumene was verified using Raman Spectroscopy (Figure 1) (ASX announcements 8 December and 15 December 2022).
Laboratory analysis has confirmed the presence of lithium and validated the Company’s initial findings, including high grade values of between 1.01% and 1.85% Li2O.
Notwithstanding the high grades from weakly weathered samples, it is noted that the strongly weathered surface samples have suffered significant lithium depletion.
See Table 1 for assay results. A more detailed description of the sampling program and results is provided in this announcement.
The Miriam leases are in the process of being granted. The Company plans to undertake detailed exploration to confirm the extent of the lithium mineralisation within the Project area, in tandem with the aggressive nickel sulphide exploration program previously proposed for the Miriam nickel-sulphide deposit. It is proposed this work will include the testing of unweathered pegmatite(s) with shallow drilling.

Table 1 – Assay Results and Descriptions
*Visual identification and quantity estimation of spodumene is based on its original crystal form in the hand specimen. Secondary processes, including alteration and weathering, can have a significant impact on lithium concentrations.
Rock samples of spodumene-rich outcropping pegmatite were extracted from a historical prospecting trench (examples shown in Figure 1). At surface, this pegmatite is weathered and the spodumene is greyish-green in colour, and replaced by albite and ultrafine muscovite (alteration and weathering processes). In less weathered pegmatite samples, the spodumene is unaltered, yellowish white in natural light and shows orange luminescence under long wavelength UV light. Spodumene crystals observed are generally 1.5-3 centimetres in width and up to 40 centimetres in length.

Rock samples submitted for analysis have an estimated spodumene content up to approximately 30% (Table 1). These visual descriptions should not be used to determine the lithium content of the pegmatite. Samples submitted for laboratory analysis were variable in character, so as to acquire information to assess the effects alteration and weathering has on the overall lithium content within the pegmatite.
Cautionary statement: Visual estimates should not be considered a proxy or substitute for laboratory analysis, which are required to determine the grade of the mineralisation.
It is expected the samples of pegmatite are a very small representation of the intrusive units that appears to strike north-south and can be traced via indications within the soil profile for at least 10 metres. The true dimensions of the pegmatites, or the representativeness of these outcrops for the entire pegmatite, cannot be determined without drilling.
The intensively weathered spodumene-bearing pegmatite samples have Li2O contents between 500 ppm and 700 ppm (Table 1). Assays from the less weathered pegmatitic material returned much higher grades, up to 1.85% Li2O. Roman Spectroscopy and whole-rock geochemistry suggest that lithium depletion on intensively weathered sample is significant.
Samples numbered CMR0016, 17 and 18 (Table 1, Figure 2) are taken from a weathered pegmatite located approximately 800 metres to the west-northwest of the pegmatite with strong visible spodumene and good lithium results. These samples have elevated lithium assays, similar to the weathered samples of the spodumene bearing pegmatite and greater than expected from barren pegmatites. This pegmatite potentially supports the prospectivity of the Miriam Project to host additional lithium-bearing pegmatites.
About the Miriam Project
The Miriam Project is located approximately 10 kilometres south-southwest of Coolgardie on a trend of ultramafics best identified by the Miriam and Nepean nickel deposits (Auroch Minerals, ASX: AOU) (Figure 3).
The Miriam Project covers an area of about 6 kilometres by 1.5 kilometers and comprises five Prospecting Licence applications (P15/6135 to P15/6139 inclusive). Corazon has acquired the rights to 100% of the Miriam Project (ASX announcement 22 April 2022), with the tenements currently in application status and in the process of being granted.
In 1969, Anaconda Australia Limited discovered the Miriam Deposit, located within the Project, and conducted most of the known nickel exploration during the late 1960s and early 1970s. This work defined the core of the Miriam Deposit over a strike of about 150 meters and to a depth of at least 150 metres below surface. In places, subsequent drilling extended the drilled depth to about 300 metres below surface. The initial defining drill intercepts for the Miriam Deposit included (ASX announcement 26 July 2021):
-
9.6m @ 5.60% Ni
-
12.5m @ 0.56% Ni
-
3.2m @ 2.59% Ni
-
0.9m @ 5.57% Ni
-
6.1m @ 0.90% Ni
Referenced open-file documents (ASX announcement, 26 July 2021) detailing historical work define a nickel-copper endowment for the Miriam Deposit. This work is not compliant with current JORC standards, and further drilling is required for the definition of a JORC resource estimate at the Miriam Project.
Much of the historical drilling which tested the ultramafic sequence north and south of the Miriam Deposit was shallow percussion drilling that did not penetrate the overlying oxidised zone, and many of the holes did not reach the ultramafic footwall target. There is extensive untested opportunity to target nickel sulphide mineralisation at depth and along strike from previous drilling.

(Crest Resources NL) and early-mid 2000’s (Berkeley Resources Limited JV’s with MPI and Sipa Exploration NL). This work continued to identify massive and disseminated nickel sulphides, located within or close to well-defined channel sequences.
The existence of this defined target trend will allow Corazon to undertake focused and detailed exploration programs, utilising modern higher-powered electromagnetic (EM) geophysics. Miriam’s most recent geophysical testwork for nickel sulphide exploration was completed in the early 2000’s, where EM proved successful in identifying drill defined mineralisation at the Miriam Deposit.

About Corazon
Corazon Mining Limited (ASX: CZN) is an Australian resource company with projects in Australia and Canada. The commodity mix of Corazon’s projects place it in a strong position to take advantage of the growing demand for metals critically required for the booming rechargeable battery sector.
In Canada, Corazon has consolidated the entire historical Lynn Lake Nickel Copper Cobalt Mining Centre (Lynn Lake) in the province of Manitoba. It is the first time Lynn Lake has been under the control of one company since mine closure in 1976. Lynn Lake hosts a large JORC nickel-copper-cobalt resource and presents Corazon with a major development opportunity that is becoming increasingly prospective in line with recent increases in the value of both nickel and cobalt metals, and their expected strong demand outlooks associated with their core use in the emerging global electric vehicle industry.
In Australia, Corazon is exploring the Miriam Nickel-Copper Sulphide Project (Miriam) in Western Australia and the Mt Gilmore Cobalt-Copper-Gold Sulphide Project (Mt Gilmore) in New South Wales.
Miriam is a highly prospective nickel sulphide exploration project, representing a strategic addition to Corazon’s portfolio of nickel sulphide assets.
Mt Gilmore is centered on a regionally substantive hydrothermal system with extensive copper, cobalt, silver and gold anomalism, including high-grade rock chip samples over a strike of more than twenty (20) kilometres. Mt Gilmore also hosts the Cobalt Ridge Deposit - a unique high-grade cobalt-dominant sulphide deposit.

The spodumene-bearing pegmatite sampled is interpreted to strike north- south, centred on approximately 6561257m N 319817m E within a radius of 5m. Samples collected from this location including CMR0001-15, 23-25. Location of the other samples are showing below: Sample ID Easting Northing CMR0016 318993 6561611 CMR0017 319068 6561624 CMR0018 319038 6561594 CMR0019 319223 6560219 CMR0020 319231 6560261 CMR0021 319719 6560989 CMR0022 319692 6560947 |
