Commenting on the 2017 year, Intermin's Managing Director Mr Jon Price said:
"The past year has been one of significant growth for the Company on the back of a highly successful exploration program, the generation of cash flow from the first stages of the Teal mining operation and a number of value accretive acquisitions and joint ventures.
"Intermin is now in a strong and quite unique position to be able to self-fund a larger Resource growth drilling program in 2018 with the focus on our key projects at the Teal gold camp, Anthill and Blister Dam with planning at an advanced stage for 50-60,000m of drilling to commence this Quarter."
"Our shareholders are very supportive of our strategy to grow our resource base above the 1 million ounce mark with an aggressive drill program and that is our key objective for 2018. We have done it before and we'll be working very hard to do it again in what is a world class gold producing region."
The following sections provide a summary of work completed and the next steps for the Resource extension programs planned for the 2018 calendar year.
Since September 2017, Intermin has been actively exploring the Blister Dam project located 54km northwest of Kalgoorlie-Boulder (see Figure 1 & 2 in link below). This region, northwest of the Kundana Goldfield, has a similar geological setting to the large open cut and underground deposits including Frog's Leg, Raleigh, Millennium and Bullant.
An Induced Polarisation ("IP") survey (see Figure 2 in link below), geological mapping, rock chip sampling and 46 RC holes for 4,180m have been completed to refine and test multiple priority targets.
Nine of the 21 individual prospects identified at Blister Dam were drilled up until the end of the field program in December 2017. The additional targets will be drilled in 2018 as part of the 5,250m follow up drilling provision as announced to the ASX on 11 July 2017.
The drilling confirmed the dominance of ultramafic and volcanic rocks and sediments with minor quartz and pyrite regularly intersected (see Figure 2 in link below). All 1m split samples have now been submitted to the laboratory and results are expected in February 2018.
In addition the Company has been awarded $60,000 in Exploration Incentive Scheme ("EIS") co-funding from the WA Government to RC drill test the recently defined IP targets (see Figure 2 in link below). The 2D dipole-dipole IP survey was completed in October and comprised approximately 98 line km. The IP results highlighted a number of small to moderate level conductor anomalies (10 - 20mV/V) and several potential (untested) fault zones.
The specific IP targets will be further refined with the addition of the outstanding drilling results and tested thoroughly with new RC drilling in the March Quarter 2018.
Teal Gold Camp
At the Teal gold project located 11km northwest of Kalgoorlie-Boulder, a total of 32 holes were completed for 3,024m at the Teal south, Jacques Find, Peyes Farm and Yolande prospects (see Figure 1 & 3 in link below). Excellent high-grade results were returned from the majority of holes intersecting both oxide and primary mineralisation (see Note 3 below) (see Figure 3 in link below).
The geology is dominated by Black Flag sediments (felsic volcanics and sediments) with lesser amounts of porphyry and intermediate volcanic rocks. Primary gold mineralisation is typically associated with quartz and sulphides and faulting has displaced or pinched out some of the mineralisation. The strong results at Jacques Find are especially encouraging and are interpreted to be the result of a cross structure intersecting a parallel structure with Teal mineralisation.
The mineralisation at Jacques Find has been intersected for at least 800m along strike and is open to the north, south and at depth.
A key outcome of the 2018 drilling program will be to define the strike and depth extents of this new discovery and determine the potential size of the deposit. The Company recognises there is potential to define a significantly larger Resource than is currently defined and will be prioritising this work to commence in the March Quarter.
Further work is planned to follow up priority targets at the Yolande, Peyes Farm and Teal NE prospects. In addition, the Company has been revising a number of potential underground targets as part of the Teal Deeps prospect. A number of deep RC/diamond holes have been allocated to "proof of concept" drilling.
Composite samples from oxide, transitional and primary material have been dispatched to Independent Metallurgical Operations Pty Ltd ("IMO") for detailed metallurgical testing. The testing will involve a staged work program comprising:
- Ore characterisation to prepare the composites for assay, provide head assay data and grind establishments for downstream testing
- Multi element analysis
- Bond Ball Work Index testing
- Determine the gravity recoverable gold content within the samples
- Determine the overall recovery of gold per composite under CIL processing conditions
- Flotation, ultra-fine grinding, roasting and pressure oxidation testwork as required
At the Anthill gold project located 54km northwest of Kalgoorlie-Boulder (see Figure 1 & 4 in link below), a total of 46 holes were completed for 6,509m with excellent results returned (see Note 4 below) (see Figures 5 and 6 in link below). Compilation of a maiden JORC 2012 Mineral Resource is now underway and is planned for completion in the current March Quarter 2018.
The geology is dominated by a variolitic basalt with lesser amounts of porphyry and ultramafic rocks observed. At least two mineralised trends are evident and add to the geological complexity at Anthill. The gold mineralisation is pervasive and occurs in a number of settings, the most important being a quartz stockwork or thin veins with carbonate-sericite-silica-sulphide alteration. Some of the gold is very coarse and is easily visible in panned RC chips.
The Anthill project will also be prioritised in 2018 and the focus will be to extend known oxide mineralisation and to undertake deeper drilling to follow up the 2017 results.
Further, Intermin has completed the field assessment of the Fire Ant prospect and areas adjacent to Anthill. A common geological theme observed is that much of the historic drilling ended in the depletion zone with encouraging amounts of quartz veining regularly intersected in the old drill spoils at surface. These have since been re-sampled and submitted for multi-element testing. New target generation studies are now underway and is planned to drill test Fire Ant and other nearby prospects in the June and September Quarters.
At the 100% owned Goongarrie Lady gold project, located 90km north of Kalgoorlie-Boulder (see Figure 1 in link below), the Company completed an infill RC drill program (167 holes for 8,447m) to confirm the grade and the geological interpretation to support the completion of a Feasibility Study and Mine approvals. Results will be combined with drilling completed in the September Quarter 2017 to compile a Resource update with the aim to increase the proportion of mineralisation in the Measured Resource category.
Due the requirement to complete drilling in addition to what was originally planned, the Feasibility Study is now scheduled for completion in the June Quarter 2018. Key activities completed or commenced include:
- Final Resource Update - commenced
- Flora and Fauna surveys - complete
- Submission of a Clearing Permit - complete
- Estimate of infrastructure, mining, haulage, processing and technical services costs - commenced
- Metallurgical Testwork - complete
- Capital cost estimate - commenced
- Geotechnical, dewatering, surface and ground water studies - commenced
- Pit optimisation study and pit design - commenced
- Submission of Mining Proposal and Mine Closure Plan - commenced.
Binduli JV (Evolution Mining)
At the Binduli gold project located 5-20km northwest of Kalgoorlie-Boulder (see Figure 1 in link below), Joint Venture partner Evolution Mining Ltd (ASX:EVN) ("Evolution") has advised it has completed 39 RC holes for 3,922m. The holes tested high priority geochemical and structural targets at the Coot & Crake and Honey Eater prospects.
Results and follow up plans are anticipated to be available in the March Quarter 2018. Under the terms of the Binduli Joint Venture Agreement, Evolution can earn 70% interest in the project by spending $4.6M over five years.
Throughout the year the Company has continued to review and explore greenfields gold projects in the region with the aim to secure new projects proximal to major geological structures with the potential to host a discovery or develop into a significant gold deposit. Intermin is working on developing a pipeline of early stage projects for target generation and drill testing.
Olympia (see Note 5 below)
At the Olympia prospect 27 holes for 2,174m were completed. The first pass aircore drilling was designed to test a 3,800m by 500m gold-in-soil auger anomaly (maximum assay 169ppb Au). Several holes returned anomalous levels of oxidised quartz-sulphide related gold and supergene mineralisation with grades up to 1.4g/t Au. Follow up work from the highly encouraging results and testing of two new areas at Olympia is planned.
Baden Powell (see Note 6 below)
At the Baden Powell prospect, eight holes for 1,364m were completed and aimed to test the depth extensions from the open pit and historical/recent drilling. A best hit of 17m @ 3.0 g/t Au (incl. 7m @ 5.95 g/t Au) was discovered in BPRC1703. The initial focus in 2018 will be on field mapping and sampling with a view to testing the Baden Powell strike and the potential for parallel structures.
At the New Mexico prospect, 12 shallow holes for 556m were completed with four holes testing each of the three tenements. The preliminary 4m composite results were encouraging with new low-grade mineralisation being discovered in two holes. The mineralisation appears to be open and untested. Individual 1m split samples are currently being collected and results are expected in the March Quarter.
The Yarmony, Area 54, Kanowna North and Windanya projects will be subject to early stage exploration techniques including auger soil sampling and aircore drilling if warranted in 2018. The strategy has proven to be successful, particularly with the advancement at the Olympia prospect.
On the back of the successful 2017 exploration program, a targeted larger scale drilling program is in the final stages of development with approvals well advanced for commencement in the March Quarter 2018.
The key business objective for 2018 is Resource growth and 75% of the planned drilling will be focussed on Resource expansion at the Teal Gold Camp and Anthill gold project. Both RC and diamond drilling will be completed to continue lateral and depth extensions to known mineralisation and to test parallel structures along strike.
Planning and preparation is also well advanced for significant drilling in 2018 at the high priority Blister Dam project and will be finalised upon receipt of first pass results in the current quarter.
The 2018 program is estimated to comprise 50 - 60,000m of drilling within a $4 million budget. The program will be fully funded from existing cash reserves generated from the Teal gold mine and through the recently approved Exploration Incentive Scheme grant.
