ASX Announcement ASX: SUP 26 September 2018 superiorlake.com.au
Significant brownfields exploration target defined at Superior Lake
Highlights
-
Brownfield exploration study defines near-mine Exploration Target at the Superior Lake Project in Canada
-
Study focused on near resource areas which can potentially be quickly added to the near term mine life
-
Exploration Target excludes untested greenfield exploration potential
-
Re-start Feasibility Study is due for completion shortly
Superior Lake Resources Limited (ASX: SUP) ( “Superior Lake” or the “Company” ) is pleased to announce it has defined an initial brownfields Exploration Target of between 2.1 to 5.2 million tonnes at a grade ranging between 13.3% to 15.4% Zn for its Superior Lake Project in Ontario, Canada.
The Exploration Target is in the immediate vicinity of the existing JORC resource of 2.15Mt at 17.1% Zn, as announced on 3 July 2018. The Exploration Target excludes the significant greenfields potential which exists at the project.
Limited exploration has been completed across the Superior Lake Project in the past 20 years, however, management is investigating a low-cost exploration program focused on these Exploration Target areas (Refer Figure 1).
*The potential quantity and grade of the Exploration Target is conceptual in nature and therefore is an approximation. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
Superior Lake Chief Executive Officer David Woodall said:
“The exploration target highlights the potential to significantly increase the resource at the Superior Lake Project in the coming years. Importantly, this Exploration Target is in close proximity to both the existing resource and vast underground mine development, therefore could potentially be converted into mine life at a relatively low cost.
In addition, we are in the final phases of completing our Re-start Feasibility Study which will be released shortly.

Brownfields Exploration Target
Superior Lake has defined a brownfield Exploration Target of between 2.1 to 5.2 million tonnes at a grade ranging between 13.3% to 15.4% Zn. This Exploration Target is in the immediate vicinity of the existing JORC resources.

*average mined grade
The Exploration Target is based on the current geological understanding of the mineralised geometry, subsurface geochemistry provided an extensive historic drill hole database and detailed underground mapping provided by historic mining activity coupled with understanding of the host stratigraphic sequence.
The Exploration Target, being conceptual in nature, takes no account of geological complexity, possible mining method or metallurgical recovery factors. The Exploration Target was estimated in order to provide the market with an assessment of the potential scale of the Superior Lake Project.
The Company intends to test the Exploration Target, based on the outcomes of further geophysical surveys and potentially with drilling. These activities are expected to extend over approximately 18 months.
Exploration Potential Estimation Methodology
The Exploration Target is defined by a combination of:
-
Drilling-informed kriged block model estimation based on resource geological wireframes where the data density and sample support does not meet the criteria for either indicated or inferred classification.
-
Extrapolation of the block modelled exploration target into extensional zones that have not been tested by drilling but in which geological continuity is supported by either geological mapping or outlying mineralised drill hole intercepts below a 1% Zn cut off that suggest continuity. Grade assigned from global average grade estimate for modeled component.
The Exploration Target is based largely on extensions of the reported classified resource into areas that have not been drill-tested in the past. These areas cover the strike and plunge continuations of the defined classified resources within host rocks that are the same as those that host the resources.

Grade ranges have been either estimated or assigned from the classified resource using either a 3% Zn cut off for the lower bound grade and 6% Zn cut off for the upper bound grade. A classification is not applicable for an Exploration Target.
Brownfields Exploration Strategy
Superior Lake’s brownfields exploration strategy is planned to leverage off the significant potential of the project area and historical high priority geophysics targets. The key activities envisaged are:
-
Complete a structural review and test a new exploration targeting model using new modern geophysical techniques;
-
Consolidate all geological, geochemical and geophysical data into a GIS database, inclusive of
-
all raw data from previous exploration activities;
-
Test areas adjacent to the current known resources with the DHTEM[1] geophysical methods for possible extensions and hidden mineralisation;
-
Test known near-surface, near mine brownfield anomalies with high-powered high-resolution TEM[2]
-
geophysics;
-
A targeted underground drilling program in, upper Pick Lake, mid Pick Lake, lower Pick Lake, as well as surrounding the Winston Lake deposit.

About the Company
Superior Lake Resources Limited
Superior Lake Resources Limited (ASX: SUP) is an ASX listed company focused on the redevelopment of the Superior Lake Project, which incorporates the Winston and Pick Lake Mines. These deposits rank amongst the highest-grade zinc deposits globally with a combined JORC resource of 2.15 Mt at 17.7% Zn, 0.9% Cu, 0.4 g/t Au and 33.5 g/t Ag. The Project is located in North Western Ontario, Canada which is rated one of the best mining jurisdictions in the world.
The Superior Lake Project has significant infrastructure in place which includes underground mine development to the existing mineralisation, tailings dams, site power connected to the grid and an allweather road. The Superior Lake Project historically produced over 3Mt of ore up until 1999 where mining was suspended due to low commodity prices.
