Central Iron Ore Ltd.: Exploration at South Darlot Gold Project

VANCOUVER, British Columbia, Sept. 25, 2021 (GLOBE NEWSWIRE) -- Central Iron Ore Ltd. (CIO – TSX.V) (“CIO” or “the Company”) is pleased to announce that an opportunity arose to drill as a drilling contractor had spare capacity.

At the Endeavour prospect 5 holes for 192 metres were drilled to test the extension of the mineralisation to the west. Significant mineralisation includes:

21ENRC-03: 2m (1.6m true width) at 9.7 g/t Au from 52 meters down hole.

On M37/632 12 holes for 726 metres were drilled to test an anomalous structure identified from a drone magnetic survey. Sample assay results from this drilling has yielded one encouraging result which was in hole 21SDRC12 and intersected 4 metres at 0.45 g/t Au from 24 to 28 metres down hole.

Drone Magnetic Survey
A drone magnetic survey was flown over 4 blocks over the South Darlot licenses on 20m flight lines and a 20m flying height for all blocks with a section over the Endeavour mineralisation flown with a 10m line spacing. The information collected from this survey was used in collaboration with an earlier 1999 survey and a drill target on M37/632 was generated. Analysis and interpretation of the data is ongoing and additional drill targets focussing on structural breaks in the geology will be made.

Trial DGPR Survey
A trial Deep Ground Penetrating Radar (DGPR) survey was conducted by Ultramag Geophysics over the Endeavour and Mermaid prospects with a series of seven lines surveyed on an approximate twenty-meter line spacing. Analysis and interpretation of the data is in progress.

Red 5 Joint Venture
The original Joint Venture was formed in 2011 with a predecessor of Red 5 Limited, who on August 2017 acquired from Gold Fields Limited the fully owned subsidiary Darlot Mining Pty Limited which held the Joint Venture interest. CIO’s fully owned subsidiary South Darlot Pty Ltd is registered at the Department of Mines, Industry Regulation and Safety with a 51% interest.

CIO maintains it is entitled to an interest of at least 70%. This is disputed by Red 5 Limited.

Red 5 Limited and CIO are in advanced negotiations to resolve this matter, which resolution will only be binding upon the execution of a definitive binding agreement. We anticipate that the matter will be resolved in the near term.

British King
Under the terms of Tenement Acquisition Agreement dated 30 October 2014 regarding the sale of British King by CIO to BK Gold Mines Pty Limited, the British King Mine has now reverted to 100% beneficial ownership by CIO. CIO is registered on title for 49% and has received signed transfer forms from BK Gold Mines Pty Limited to Central Iron Ore Limited for the transfer of a further 51% interest as agreed.

The registration of unencumbered title of that 51% interest is being delayed by Silverstream SE22, who provided funding to BK Gold Mines Pty Limited to fund their acquisition under the Tenement Acquisition Agreement. Silverstream SE22 has refused to remove the caveats which prevents registration of the transfers. CIO maintains that such refusal has no legal foundation and is evaluating its options which includes commencing legal proceedings.

SOUTH DARLOT GOLD PROJECT (Western Australia)

The Company’s South Darlot Gold Project area is located approximately 320km northwest of Kalgoorlie in Western Australia and includes:

• The British King Mine which is National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI43-101”) compliant. The British King Mine is 5km southwest of Red 5 Limited’s Darlot Mine. The British King Mine is currently in care and maintenance.
• A number of tenements which are subject to a joint venture with subsidiaries of Red 5 Limited (“Red 5”), details of which are set out below.

RED 5 JV Project (Formerly Barrick Joint Venture Project)

The tenements set out in the table below (“Red 5 JV Tenements”) are the subject of a joint venture between the Company and subsidiaries of Red 5 Limited (“Red 5 JV”) and are situated southwest of Red 5’s Darlot gold mine and are contiguous with CIO’s current holdings in the area. The Red 5 JV Tenements are detailed below.

Endeavour Prospect – RC Drilling

The Endeavour mineralisation is characterised by a planar, laminated quartz vein with minor sulphides including pyrite, galena and traces of chalcopyrite. Enveloping this is stringer mineralisation over 1 – 3 metres with grades between 0.5 – 2.0 g/t Au. This laminated vein and halo mineralisation is hosted in a highly weathered felsic volcanic. Preliminary petrology suggests the gold is secondary in nature and present as small blebs of electrum or particulate grains associated with pyrite.

A total of five holes were drilled at the Endeavour prospect in July 2021. Four of the holes targeted shallow positions in an attempt to determine the up dip presence of the Endeavour mineralisation. The fifth hole was drilled to extend the mineralisation to the west of the Endeavour quartz lode.

The four shallow holes intersected a narrow 1 to 2 m wide quartz vein but failed to record any significant mineralsiation and it must now be concluded there is a depletion zone in the highly weathered upper horizon of this mineralised system.

The fifth hole 21ENRC-03 targeted the quartz lode west of the known position of the lode and intersected 2 m @ 9.7 g/t Au from 50 metres down hole (true width of 1.6 metres). Figure 2 to 4 shows a plan, cross section and long section of the Endeavour lode and the spatial relationship of the intercept relative to historical drilling.

M37/632 – RC Drilling

A structural target generated from the recent drone magnetics survey was drilled in July 2021. A total of 12 reverse circulation drill holes were drilled on three lines spaced 80 metres apart. A total of twelve holes were drilled for 726 metres. Sample assay results from this drilling has only yielded one modestly interesting result which was in hole 21SDRC12 and intersected 4 metres at 0.45 g/t Au from 24 to 28 metres down hole (Table 2). This was a 4 metre composited sample, and the individual one metre samples will be submitted for fire assay analysis.

Drone Magnetic Survey

A low level, high-resolution rotary wing, drone-based magnetic survey of the South Darlot licenses on 20m flight lines and a 10m flying height covering an area of 6.6 km² was flown over four areas in May 2021 by Ultramag Geophysics. The objective of the survey was to ascertain if geological breaks in stratigraphy representing structural discontinuities could be identified with the close spaced, high resolution data. Preliminary work has identified one such structure which was drill tested in July 2021. Further analysis of this data set will be undertaken to determine its usefulness for drill targeting.

Trial Radar Survey

A trial Deep Ground Penetrating Radar (DGPR) survey was conducted by Ultramag Geophysics over the Endeavour and Mermaid prospects with a series of seven lines surveyed on an approximate twenty-meter line spacing. The specifications of the survey are as follows: 20 kW, 3 µs pulse width, 15,000 Hz with a 1 second sample which is equivalent to 1 meter shot spacing.

Results from the survey are still being analysed; however, the initial findings are proving difficult to correlate to the known spatial position of the Endeavour lode. A fault like feature can be observed to the south of the Endeavour lode (Figure 8) however, this is lost in the subsequent radar sections.
