Rover Metals identifies exploration targets at its Cabin Lake gold project

Published by , Assistant Editor
Global Mining Review,

Rover Metals Corp.’s (Rover Metals) technical team has identified its drill targets for the Cabin Lake gold project (the Property) based on a combination of (i) its interpretation of historic workings and (ii) the recently completed geophysical and geochemical programme performed in 3Q18 and 4Q18.

Judson Culter, CEO at Rover Metals, stated: "The 2018 magnetic survey and soil sampling programme results have expanded the anomalous zones and expanded on the known gold mineralised zones. Within these zones, we have identified the best drill targets for converting the historic drill results into current NI 43-101 resource standards. The new targets were developed from the reinterpretation of the historic work programmes completed to date, which included over 7500 m of diamond drill data purchased from North Arrow Minerals – a legacy asset from exploration drilling completed by Aber Resources (Grenville Thomas) in the late 1980s."

The company has found and GPS referenced all the historic blasted trenches and small pits at the Andrew North and South Zones, as well as those located at the Beaver, Camp and other locations within the Property. The UAS magnetic survey was key to providing the desired resolution and contrast on the Bugow Iron Formation, known host of the Property's gold mineralisation. The 2018 ground geochemical soil survey produced multi-element (Au-Ag-As-S-Cu) anomalies over known mineralization zones and additional zones coincident with conceptual mineralized targets.

Three zone were prioritised for the 2019 diamond core drilling campaign: the Cabin Lake Gold Zone, the Andrew South Hinge Zone and the Andrew North Hinge Zone.

Cabin Lake Gold Zone

This mineralised zone is the anchor mineralised zone for the Property. It has a historic non-NI 43-101 compliant resource estimate of 100 000 t grading 10 gpt Au. Mineralised zone strike length is over 100 m and to a shallow depth of 70 m from surface. The best historic mineralised diamond core drill holes reported by Aber Resources include 15.0g/t Au over 12.1m (in hole DDH86-28); 15.8 g/t Au over 8.02 m and 9.6 g/t Au over 1.04 m (in hole DDH86-12); and 12.5 g/t Au over 4.1m (in hole DDH86-26), amongst other encouraging drill intercepts.

Rover Metals will continue to diamond core drill this zone at different hole geometries, with  a larger area diamond drill core diameter (NQ2 or HQ) in order to both validate the historical intercepts and  continue to expand the mineralized zone along strike and depth.


Andrew South Hinge Zone

This mineralised zone has been expanded from the reinterpretation of the historical data. The Bugow Iron formation surface  projections from the UAS magnetic survey clearly indicates the historic mineralised zone geometry is comprised of 100 m long tight fold closure (hinge) of a synform that wraps along the Bugow Iron Formation and continues to the northwest. The topography is also recessive on that flank of the synform and the intensity of the Total Magnetic response may indicate sulfidisation, in a very similar arrangement as the Cabin Lake Gold Zone. More than 20 historic pits/trenches have been identified  by GPS surveying. The Andrew South zone has a non-NI 43-101 compliant resource estimated at 43 900 t grading 4.39 gpt Au.

A diamond core drill programme has been designed follow the hinge down dip under the historic open cut towards the northwest following the fold limb in areas or reduced magnetic intensity that suggest higher sulfide content as replacements of the Iron Formation as part of the proven geologic model.

Andrew North Hinge Zone

This mineralised zone has been reinterpreted from historical data. The fold closure (hinge) geometry correspond to an antiform and it is more open than at the Andrew South. All trenches/pits have been GPS located. The Andrew North zone has a non-NI 43-101 compliant resource estimate of 18 100 t grading 7.89 gpt Au.

A diamond core drilling programme has been designed to further investigate areas of reduced magnetic intensity within the Bugow Iron formation at the hinge zone coincident with recessive topography, to test for gold mineralisation.

Other zones

Additional shear zones and parallel sets of sulfidised iron formations have been located in other parts of the Property and a meaningful exploration programme has been designed  to perform prospecting, mapping, and sampling.
