Fireweed Announces Borehole Muon Tomography Survey at Macmillan Pass

Fireweed Zinc LTD. ("Fireweed") (TSXV: FWZ) is pleased to announce that it has partnered with Ideon Technologies ("Ideon") to undertake a muon tomography survey this summer at the Macmillan Pass project, Yukon, Canada. Muon tomography is a field-proven geophysical technique that uses naturally occurring cosmic-ray muons to measure density contrasts and identify subsurface anomalies such as dense bodies of zinc mineralization. This will be one of the world's first deployments of Ideon's borehole muon detectors, which can fit inside an HQ-size drill hole and provide high-resolution, straight-line imaging up to 1 km beneath the surface.

Highlights

  • Cutting-edge borehole muon tomography technology to be deployed at Boundary Zone and Tom East to detect density anomalies in the subsurface, which may be used to guide future drilling.
  • Potential to detect new exploration targets, provide detailed imaging of existing targets, and reduce the overall cost of exploration by saving drill-metres.
  • Muon tomography is a directional imaging method, allowing the source of density anomalies to be pinpointed accurately.

CEO Statement

Brandon Macdonald, CEO, stated, "Muon tomography as a science has been around for decades but the new technological breakthrough for mineral exploration is building a compact muon detector that can fit inside a drill hole and image up to 1 km underground to then generate high-resolution 3D subsurface models. This is potentially game-changing technology that we are leveraging to become a first mover in using borehole muon tomography surveys for zinc exploration. We see value in using this technology to model the dense bodies of mineralization during early stages of drilling to maximize the efficiency of drilling out a deposit. We also see great potential in using muon tomography to discover new zones that may have evaded detection by more traditional exploration methods."

Muon Tomography

The borehole muon tomography technology has been developed by Ideon Technologies ( www.ideon.ai ), a spin-off from TRIUMF (Canada's national particle accelerator laboratory) and a world pioneer in the application of cosmic-ray muon tomography. Ideon has developed a discovery platform that integrates proprietary detectors, imaging systems, inversion technologies, and artificial intelligence techniques to provide visibility up to 1 km beneath the Earth's surface – much like x-rays and MRIs provide visibility inside the human body.

Fireweed has contracted Ideon to deploy borehole muon detectors and to transform the data captured into reliable geophysical surveys and 3D density maps, enabling a new dimension for exploration at the Macmillan Pass project.

A muon (pronounced myoo·on ) is a naturally occurring sub-atomic particle created as a result of supernova explosions in space. Resultant cosmic rays collide with matter in the Earth's upper atmosphere to create a muon flux that travels to Earth in straight lines at almost the speed of light. Muons lose energy progressively as they pass through the Earth's surface. As they encounter higher-density material, muons lose energy at an accelerated rate. The directional muon intensity can be measured by each borehole detector deployed. Multiple 2D images are then combined to map density in 3D. This overall process is known as muon tomography. Unlike potential field geophysical methods such as gravity and magnetic surveys, muon detectors provide directional imaging (recording the muon arrival direction), allowing anomalies to be located in 3D space by combining measurements from several detectors positioned at different locations underground.

Typically, a borehole muon survey will take on the order of weeks to months to complete, depending on geology, depth of borehole, and imaging target. Ideon will deploy ten borehole detectors during the survey in configurations optimized to best image the exploration targets. Multiple detectors can be placed down individual HQ size drill holes once the rods have been removed and the surface casing remains in place. Several drill holes will be surveyed simultaneously to produce robust inversions of the subsurface density.

Exploration targets

The first survey is planned at Boundary Zone West where Fireweed made a discovery of near-surface massive sulphides in 2020 (see Fireweed news releases dated September 24 th , 2020, November 24 th , 2020, and February 3 rd , 2021) and where there is a high density contrast between the massive sulphides and the host rock. Siderite, a dense iron carbonate mineral, is intimately association with zinc mineralization at Boundary Zone and together with galena, sphalerite and pyrite occur as dense bodies that are amenable to detection using muon tomography. Imaging these dense bodies in 3D will enable Fireweed to better target high-density zones and optimize subsequent drilling thereby reducing overall program costs.

Additional muon tomography surveys are planned at Tom East, a high-grade zone with a current Mineral Resource of 0.81 Mt at 8.74% Zn, 8.62% Pb, and 110.0 g/t Ag Indicated resource in addition to 1.68 Mt at 9.86% Zn, 12.86% Pb and 170.0 g/t Ag Inferred Resource (see Fireweed news releases dated January 10 th , 2018, and reports filed on www.sedar.com for details). In 2018, Fireweed drilled a very-high grade step-out hole at Tom East in an area outside of the current Mineral Resource, intersecting 16.41 m of 21.1% Zn, 13.5% Pb and 243.0 g/t Ag (see Fireweed news release dated September 20 th , 2018) in an interval containing the dense minerals galena-sphalerite-barite-pyrite-pyrrhotite. A borehole muon survey is planned at Tom East to determine if a dense 3D body can be imaged around this step-out intersection to better target follow-up drilling.

Vertex Minerals Limited Acquires Drill Rig to Advance Exploration, at the High-Grade Reward Gold Mine, Below the Existing Resource

Sydney, Australia (ABN Newswire) - Vertex Minerals Limited (ASX:VTX) (OTCMKTS:VTXXF) is pleased to report the acquisition of a Boart Longyear LM90 underground drill rig, in line with its stated strategy to advance exploration drill works at the high-grade Reward gold mine.

HIGHLIGHTS

- Vertex has acquired a Boart Longyear LM90 underground drill rig to advance exploration at the Reward gold mine below the existing resource

- The Vertex team are planning diamond drill programs for the following:

o Below the current JORC-2012 Reward Resource (see drill collar locations on Figure 1), with the aim of expanding upon the existing resource

o Fosters Exploration Target, and the South Star prospect area

- Acquisition of the LM90 follows an extensive review of the mineralisation potential below the Reward resource, which has only been drilled up to 50m below the Amalgamated Adit. This area targeted is referred to as the 'Reward mid depths' as it is located just 80m to ~200m below the Amalgamated Adit. Refer to figure 1*

- Upon commissioning of the LM90 drill rig, Vertex have planned eight drill holes to target the high-grade Fosters Exploration target

- The LM90 has several advantages well-suited to Vertex's requirements, including:

o The ability to work on surface and underground

o Safe, Semi-automated, with a rod-handler system which allows for less manual handling

o Allows greater flexibility in drilling over a number of resource and exploration areas

o LM 90 rigs are well-established in the industry as safe and reliable underground drill rigs

- Vertex acquiring its own rig has many advantages

o Per-metre drill costs will be significantly less than hiring an external drill contractor

o More control and accuracy over precision of drilling.

o Works well with Job sharing

o Reduces pressure on Mining crew to have drill cuddy availability

o The LM90 rig will be accounted for as an asset on the Vertex balance sheet

Executive Chairman, Roger Jackson, commented: "The acquisition of the LM90 was completed on attractive commercial terms, and followed an extensive review process by the field operations team to acquire a rig that was fit-for-purpose to advance our broader exploration strategy. This is an important development for Vertex and we're excited to get started with targeted drill works that have the potential to unlock significant value from the project. Our analysis has shown that it is significantly cheaper, safer and more practical to drill the Reward mine from underground, which is exactly what the LM 90 allows us to do. With an extensive framework of priority drill targets already set out, we look forward to advancing exploration and building on what is already an exciting resource at the Reward mine."

LONGYEAR LM90 UNDERGROUND DRILL RIG - KEY FEATURES

The LM90 has several attributes which will provide flexibility for on-site drilling operations, where Vertex will be able to maintain drill sites with the Company's own underground mining crew. The deployment of the LM90 also means Vertex does not have to pay stand-down time or mobilisation fees, and its drillers can be assigned to other jobs.

1. REVERSIBLE FEED CYLINDER

The feed cylinder is reversible which increases up-hole drilling capacity.

2. SEMI-AUTOMATED ROD HANDLING
