Corazon Mining Ltd (ASX:CZN) is maintaining a dual focus at the Lynn Lake Nickel-Copper-Cobalt Sulphide Project in Manitoba, Canada - exploring for new nickel sulphide deposits whilst conducting studies for the re-establishment of mining at the historical Lynn Lake Mining Centre.
The company has completed a high-powered, ground-based 3D induced polarization (IP) geophysical at the Fraser Lake Complex (FLC).
FLC is located five kilometres south of the historical Lynn Lake Mining Centre and is a focal point of exploration for Corazon (Figure 1).

The survey is designed to better define the size and depth extents of the extensive sulphide mineralisation intersected at the FLC by wide-spaced drilling completed to date.
The fieldwork for the 3D IP survey has been completed, with data processing and target generation expected to be finalised by the end of May.
Lynn Lake re-development
Corazon is also continuing to test the opportunity for the re-development of the Lynn Lake Mining Centre.
Detailed processing, mining and resource studies currently in progress are looking to optimise Lynn Lake as a long-life, low-cost, nickel sulphide mining operation.
The current phase of 'ore-upgrade' test work will be completed by the end of May.
New mineral resource estimates are expected to be finalised by the end of July, with mining and development studies ongoing throughout this process.
Bulk-scale metallurgical test work underway
A new round of metallurgical test work at Lynn Lake has started.
This is an integral part of the current mining and processing studies being undertaken at the project, and the work currently underway includes:
- Finalising the flotation process;
- investigation of pre-flotation ore-upgrade of low-grade material; and
- initial work on the amenability of Lynn Lake mineralisation to produce battery-grade products for rechargeable lithium-ion batteries.
Additionally, such ore types typically have no problem producing high-quality battery-grade products.

Bench-scale ore-upgrade and ore-sorting test work completed on low-grade material from the EL Deposit has returned encouraging results.
The next phase of work will include both bench-scale and bulk-scale test work, investigating several processing techniques.
Metallurgical test work is a key component of Corazon’s strategy to transform Lynn Lake into a long-life, low-cost, nickel sulphide mining operation.
The work underway is expected to be completed before the end of May 2023.
