Rachel Backus Joins GreenTech Metals as Chief Geologist from Leeuwin Metals<\/h2>
In its 6 July 2026 company update, GreenTech Metals confirmed that Ms Rachel Backus will take on the role of Chief Geologist starting 27 July 2026. She joins from Leeuwin Metals Ltd (ASX:LM1), where she served as Exploration Manager. This appointment introduces an experienced exploration leader into a newly established senior position as GreenTech prepares for an intensified drilling phase.<\/p>
The company update highlights this hire as part of a strategic expansion of GreenTech’s internal technical expertise. Moving beyond reliance on external consultants, GreenTech is assembling a dedicated team of specialists to manage complex, multi-commodity exploration projects internally. CEO James Rattenbury noted that Backus joins a growing technical team complemented by world-class advisors, indicating a comprehensive approach to technical leadership.<\/p>
Backus’s Extensive Exploration Experience Covers Gold, Nickel, Copper, and PGE Systems<\/h2>
Backus’s professional background spans a wide array of commodity systems, including gold (Au), nickel (Ni), copper (Cu), manganese (Mn), iron (Fe), and platinum group elements (PGE). This expertise directly aligns with GreenTech’s core projects — the Munni Munni PGE-Cu-Ni and Whundo Cu-Zn-Au projects — both situated in Western Australia’s West Pilbara region. Her hands-on experience encompasses generative targeting, drill programme design and execution, and resource expansion, all critical as GreenTech advances to active drilling.<\/p>
Particularly pertinent to GreenTech’s flagship Munni Munni asset is Backus’s nickel-copper-PGE experience gained at Western Areas, a company known for high-grade nickel sulphide deposits in Western Australia. This background closely matches the geology of the Munni Munni layered mafic intrusion, regarded as one of Australia’s most significant PGE deposits, containing platinum, palladium, rhodium, gold, copper, and nickel within a large, continuous reef structure.<\/p>
Career Includes Senior Roles at Fortescue, Western Areas, and Multiple ASX-Listed Explorers<\/h2>
Backus’s career history includes senior positions at prominent Australian mining and exploration companies such as Fortescue Metals Group, Western Areas, Prodigy Gold, Consolidated Minerals, Orion Gold, Tanami Gold, and Saturn Metals. This diverse experience reflects exposure to varied geological settings, project stages, and corporate environments across the Western Australian resources sector.<\/p>
Her background is notable for a company at GreenTech’s exploration stage, combining experience in large-scale mining operations with the focused, capital-efficient approach typical of junior explorers. This blend is expected to enhance the efficiency of GreenTech’s forthcoming drilling programme across its extensive West Pilbara landholding exceeding 500 square kilometres.<\/p>
Academic Credentials and Professional Memberships Support Competency<\/h2>
Ms Backus holds a Master of Geology with Honours from the University of Leicester, a Graduate Certificate in Geostatistics, and a Certificate in Mining Studies. She is a member of the Australasian Institute of Mining and Metallurgy (AusIMM) and the Australian Institute of Geoscientists (AIG). These affiliations qualify her as a Competent Person under the JORC Code for reporting mineral resources and exploration results.<\/p>
This combination of advanced geology education, specialist geostatistics training, and professional memberships equips Backus to lead both field programme design and technical reporting. For GreenTech, advancing resource definition drilling at Munni Munni and Whundo, having a qualified Chief Geologist in-house represents a vital operational milestone.<\/p>
CEO James Rattenbury Highlights Upcoming Transformative Drilling Phase<\/h2>
CEO James Rattenbury described Backus’s appointment as a key step in building the in-house technical capability needed for an exciting forthcoming programme. He emphasized her 18-plus years of exploration experience across Western Australia, including nickel, copper, and PGE, as making her exceptionally suited to lead geological efforts at Munni Munni and Whundo.<\/p>
Rattenbury characterized the current period as transformative for GreenTech’s drilling activities, signaling the company’s anticipation of a pivotal phase in its exploration journey. Although specific details on drilling timelines, budgets, or targets were not disclosed, the CEO’s remarks indicate high expectations for the upcoming field campaign. Investors should watch for further announcements detailing drill targets, estimated metres, and assay schedules.<\/p>
Munni Munni PGE-Cu-Ni Project Central to Appointment<\/h2>
GreenTech describes the Munni Munni project as one of Australia’s most significant platinum group element layered mafic intrusions. The project features a large, laterally continuous reef historically known to contain platinum, palladium, rhodium, gold, copper, and nickel. Located within GreenTech’s West Pilbara landholding, Munni Munni is one of two key projects being advanced concurrently.<\/p>
The appointment of a Chief Geologist with direct PGE and nickel-copper sulphide expertise, particularly from Backus’s experience at Western Areas, aligns with the geological complexity of Munni Munni. Layered mafic intrusions hosting PGE mineralisation require specialized skills, indicating Munni Munni will be a primary focus of the imminent drilling programme.<\/p>
Whundo Cu-Zn-Au VMS Project to Benefit from Backus’s Multi-Commodity Expertise<\/h2>
Alongside Munni Munni, GreenTech is progressing the Whundo project, an advanced, high-grade brownfield volcanogenic massive sulphide (VMS) copper-zinc-gold deposit with significant potential for resource expansion. Located about 10 kilometres from Munni Munni within GreenTech’s broader West Pilbara tenements, Whundo sits along a highly prospective structural corridor offering further exploration upside.<\/p>
Backus’s experience across copper and gold systems, in addition to PGE and nickel, positions her to contribute to both core assets. GreenTech’s strategy of managing two complementary deposits in the same district appears to have influenced the decision to appoint a Chief Geologist with multi-commodity expertise. Her responsibilities will span both Munni Munni and Whundo as the company advances its field activities.<\/p>
Extensive West Pilbara Landholding Supports Exploration Ambitions<\/h2>
GreenTech Metals holds one of the largest tenement positions in the West Pilbara, exceeding 500 square kilometres. The company aims to discover, define, and develop a multi-commodity district to meet growing demand from green energy and critical minerals markets. This extensive tenure suggests a substantial exploration workload beyond Munni Munni and Whundo, including generative work across underexplored areas.<\/p>
Given the scale of its landholding, appointing an experienced Chief Geologist skilled in generative targeting is operationally significant. Generative targeting involves identifying new mineralisation prospects using geological, geochemical, and geophysical data, highlighting GreenTech’s potential focus on discovering additional targets within its West Pilbara portfolio.<\/p>
Building an In-House Technical Team Reflects Shift to Active Exploration<\/h2>
Backus’s appointment as part of a deliberate build-out of in-house technical capabilities signals GreenTech’s strategic shift. Unlike many early-stage ASX explorers that rely heavily on external consultants, GreenTech is investing in permanent senior technical staff to support sustained, large-scale exploration programmes.<\/p>
CEO Rattenbury’s mention of a growing technical team including world-class advisors suggests Backus’s hiring is one element of a broader staffing initiative. While further details on other team members or advisors were not disclosed, this language implies additional appointments or engagements may be underway. For investors, the technical team’s composition and expertise will be a key indicator of GreenTech’s readiness to execute its drilling plans.<\/p>
Share Price Impact and Drilling Details Await Further Disclosure<\/h2>
The immediate impact of Backus’s appointment on GreenTech’s share price was unclear at the time of the update. Such personnel moves are typically evaluated by the market in the context of broader catalysts — in this case, the upcoming drilling programme — rather than as standalone events. Nonetheless, for investors following GreenTech’s development, hiring a highly qualified Chief Geologist with relevant PGE and nickel-copper experience may be viewed positively as a sign of operational momentum.<\/p>
The company has yet to reveal specifics regarding the timing, scale, budget, or targets of the planned drilling campaign. The next important milestone for investors will likely be a detailed programme announcement outlining drill targets, estimated metres, and assay timelines for Munni Munni and Whundo. Given the CEO’s reference to an imminent transformative drilling period, such updates are expected soon.<\/p>
