Nine Mile begins drilling at California Lake

Mr. Patrick Cruickshank reports


Nine Mile Metals Ltd. has initiated its California Lake VMS (volcanogenic massive sulphide) drill program. Les Forages Chapais from Sussex, N.B., has been engaged to drill these high-priority targets, beginning with target No. 10, drill hole CL-23-10-01.

Over the past year, the company’s geophysical technical advisers, EarthEx Geophysical Solutions, and its newest technology partner, Earth Sciences Services Corp. (ESSCO), have both independently identified the company’s western portfolio targets. Initially, EarthEx reprocessed the legacy MegaTEM data with its proprietary technology, highlighting the late time conductive electromagnetic responses and defining the strong-to-medium and lower-priority conductive axes. Both individual targets and target trends were identified. ESSCO identified the subsurface 3-D density targets consistent with existing Bathurst mining camp VMS deposits as baseline models for its technology processes.

Approximately four months ago, ESSCO approached Nine Mile and introduced its proprietary technology (acoustic EM (electromagnetic)) to Nine Mile. This technology was developed as a regional screening tool to facilitate targeting within large, known productive mineralized camps such as the Bathurst mining camp (BMC). Utilizing a fixed wing passive EM system, ESSCO independently flew the BMC with its proprietary system in order to model the Brunswick No. 12 and search for similar areas. The results of the regional testing returned only a few target regions which fit the size and scope parameters of the Brunswick No. 12 deposit model, the largest priority target being No. 10, along the California Lake West VMS trend. Once identified, and in co-ordination with Nine Mile, further on-site data collection was undertaken to facilitate 3-D modelling. The first stage was ground level follow up utilizing acoustic-transponder reference stations and a local-scale drone supported (acoustic EM) survey to outline the target’s acoustic density isoshells. Further refinement of the data defines the internal density structure which, in the case of California Lake target No. 10, revealed five independent lenses, the target density component integrating multiple data streams in addition to both conductivity and resistivity.

Patrick J. Cruickshank, chief executive officer and director, stated: “We have assembled the best leading technologies for exploration of VMS in the BMC. We are encouraged that our geophysical modelling and partners have identified the same priority targets on California Lake and the Wedge projects independently. Having our technical team locate size and scale targets with the parameters of the BMC deposit model is encouraging. ESSCO has developed their technology based on magnetotelluric methods utilized in hydrocarbon exploration (that is, Exxon, Mobil), integrating their own proprietary technology and processes to define density targets. They used the famous Brunswick No. 12 deposit as their baseline for locating additional potential deposits. This compilation of targets supported by different technologies using different processes and algorithms has moved our exploration program leaps forward. ESSCO’s technology is scalable, and we are testing the largest target in the western portfolio on the favourable horizon, the targeting further supported by the geology, soils and sampling. We are prioritizing CL-23-10-01 to utilize our previously announced N.B. JMAP grant that must be completed this calendar year. We look forward to announcing results in the coming weeks. Our recent land acquisitions have made it possible to finalize our technology targeting process on our entire Nine Mile Metals portfolio. We have our exploration road map for years to come.”

The Chapais drilling team has 99 years of combined experience since 1966 and, in the past 56 years, Chapais has successfully completed surface and underground drill programs at the Brunswick No. 12, Brunswick No. 6, Heath Steele and the Caribou deposits. Chapais has specific BMC-style VMS expertise in addition to experience drilling deep holes in difficult terrain. The company looks forward to its technical execution for this deep hole, utilizing its skid mount drill rig with hex casing and Reflex Gyro technology to keep the hole on target. Chapais also integrates Starlink satellite Internet technology at its rig, providing instant drill hole monitoring and metrics in real time.

The data processing by ESSCO is unique and incorporates acoustic waveform data in its density modelling. Acoustic waveform data has previously been regarded as noise in the dataset, however, ESSCO has developed its unique data capture while AI (artificial intelligence) processing converts both the conventionally captured and new technology captured data into both a lithology and mineralization density isoshell model. Further processing by ESSCO provides drill collar information to optimally test these priority targets. Nine Mile will test this technology with drill hole CL-23-10-1. Drilled at an azimuth of 205 degrees and a dip of minus-73 degrees, the top of the target is 705 metres while the total depth may extend to 1,000 metres.

The disclosure of technical information in this news release has been prepared in accordance with Canadian regulatory requirements as set out in National Instrument 43-101 — Standards of Disclosure for Mineral Projects, and reviewed and approved by Gary Lohman, BSc, PGeo, vice-president of exploration and director, who acts as the company’s qualified person and is not independent of the company.

About Nine Mile Metals Ltd.

Nine Mile Metals is a Canadian public mineral exploration company focused on critical minerals exploration (CME) VMS (copper, lead, zinc, silver and gold) exploration in the world-famous Bathurst mining camp, New Brunswick, Canada. The company’s primary business objective is to explore its four VMS projects: Nine Mile Brook VMS; California Lake VMS; Canoe Landing Lake (East-West) VMS and its new Wedge VMS projects. The company is focused on critical minerals exploration, positioning for the boom in EV (electric vehicles) and green technologies requiring copper, silver, lead and zinc, with a hedge with gold.
