In-country refining and manufacturing take Papua New Guinea\u2019s resources to the next level
\nASX companies Taruga Minerals and Pacific Lime and Cement take a stake in growth
\nNew mining laws underpin PNG\u2019s quest to be a leading Asia-Pacific investment spot\u00a0<\/p>\n
\u00a0<\/p>\n
Papua New Guinea\u2019s resources sector is moving towards a nation-building role as in-country refining and manufacturing add depth to the economy.<\/p>\n
Known for its copper and gold, there are plenty more local materials that are ripe for downstream value-adding to displace imports and lessen the burden of international shipping costs.<\/p>\n
Imagine local quicklime being used for gold processing at the nation\u2019s world-class tier-1 assets and locally sourced cement forming new roads and bridges.<\/p>\n
Or new deposits paying future dividends on the scale of the Ok Tedi copper and gold mine where the mill handles 80,000t of material a day.<\/p>\n
New projects are promising not just exports, but local industry, infrastructure, jobs and a direct stake in the nation\u2019s future.<\/p>\n
And there\u2019s a handful of ASX companies contributing to that step change.<\/p>\n

High-impact Weioko<\/p>\n
Rather than sitting next to a major producing mine, Weioko on Normanby Island in Milne Bay is a gold discovery in itself.<\/p>\n
Taruga Minerals\u2019 (ASX:TAR)<\/a> Weioko deposit sits within an extensive 40km-long epithermal gold belt. It\u2019s soon beginning a maiden drill program, after some heady share price movement and encouraging early exploration.<\/p>\n A 33.1g\/t Au rock chip sample from the Wenasia prospect is Taruga\u2019s highest gold grade recorded to date, with the sample collected from a newly defined outcropping quartz vein.<\/p>\n The under-explored Weioko gold district has an 8km-long mineralised corridor running from Wenasia in the south to Sipupu prospect in the northeast.<\/p>\n Follow-up sampling extending into the EL2831 tenement that was granted in June has located the outcropping source of gold-silver previously flagged to be upstream.<\/p>\n Combined with the adjacent EL2830 and EL2590 licences, the grant expands the total exploration footprint to 488km2 as Taruga presses ahead with a Weioko gold district expansion.<\/p>\n Combined with previously reported and historical results for Weioko, high-grade gold and silver mineralisation has been identified at surface across the district, with 14 of 44 rock chip samples returning above 0.5g\/t Au and six above 5g\/t Au.<\/p>\n \u00a0<\/p>\n Rig set to spin<\/p>\n \u201cWe flagged the Sipupu float sample as pointing to a source upstream back in July, and we walked straight to it,\u201d TAR chairman Paul Cronin says.<\/p>\n \u201cWenasia has played out in a similar way, with these high-grade results validating a recent director site visit observation where locals were panning gold in the Wenasia creeks.<\/p>\n \u201cWith high-grade outcropping vein systems confirmed across the 8km Weioko gold district, and the maiden rig on track to mobilise at the end of this month, we\u2019re heading into a high impact Q4 for Taruga.\u201d<\/p>\n According to preliminary metallurgical testwork, Weioko gold is free-milling and worth the effort.<\/p>\n A high-grade composite grading 14.15g\/t Au returned 96.3% gold extraction in preliminary testwork.<\/p>\n But even a \u201clow-grade\u201d composite (0.59g\/t Au and 4g\/t Ag head grade) returned 92.6% gold and 92.2% silver extraction, pointing to consistency.<\/p>\n The coarse free gold was found to be recoverable by gravity separation, with the remaining finer gold suiting conventional cyanide leaching.<\/p>\n \u00a0<\/p>\n More than a lark<\/p>\n The Solomon Sea is also home to Geopacific Resources (ASX:GPR)<\/a> and its operations on Woodlark Island.<\/p>\n The 1.98Moz Woodlark gold project sits roughly 600km east of Port Moresby and 300km northeast of Alotau in Milne Bay Province.<\/p>\n Approval in principle was granted in 2013, an Environmental Impact Statement (EIS) was completed in 2013 and a Definitive Feasibility Study<\/a> was completed in 2026.<\/p>\n The study confirmed the long-life open-pit gold development was \u201ctechnically robust, economically attractive\u201d and \u201cforecast to generate strong free cash flow and rapid capital payback\u201d.<\/p>\n The pre-tax NPV was $1.78 billion (post-tax $1.3bn) at a $5500\/oz gold price.<\/p>\n Undiscounted life-of-mine revenue was $6.1bn, with post-tax net cashflow of $2.5bn for a post-tax payback period of just 18 months from first production.<\/p>\n The life-of-mine all-in sustaining cost (AISC) was set at just $1966\/oz gold, underpinned by a 1.2Moz Au ore reserve.<\/p>\n The 3.5Mtpa processing plant was forecast to produce an average of more than 100koz of gold annually, with an average gold recovery of 89.7%.<\/p>\n Managing director Hamish Bohannan says the DFS came at a time of increasing international interest in resource development and infrastructure investment in PNG.<\/p>\n The country is of growing strategic importance as a destination for large-scale resource projects and a key supplier of precious metals to global markets, he says.<\/p>\n And the gold price is now north of A$6000\/oz, according to live trackers from the Perth Mint. Unsurprisingly, Geopacific is now drilling for near-mine resource extensions.<\/p>\n \u00a0<\/p>\n For the people<\/p>\n State nominee companies are now utilised to take stakes in significant projects, which gives the people of Papua New Guinea a slice of the action.<\/p>\n It\u2019s part of a global trend of governments taking a direct equity stake in mining and energy projects rather than just being the land regulator and relying on future royalties or taxation.<\/p>\n This kind of arrangement is increasingly a dealmaker, not a dealbreaker, for key sectors like mining to play a role in nation-building.<\/p>\n When Pacific Lime and Cement (ASX:PLA)<\/a> declared its final investment decision (FID) in August 2025, it was the first FID for a major mining project in PNG in 18 years.<\/p>\n That sent a strong signal to the investment community, as the first to get across the line since past oil and gas FIDs.<\/p>\n Co-ownership of the Central Lime and Central Cement project at Kido and Rea Rea in the Central Province was locked in under a Project Development Agreement (PDA) signed in March 2026.<\/p>\n For Pacific Lime and Cement managing director Paul Mulders, the government\u2019s decision to invest directly in the project strengthens the sovereign and institutional foundations of what they are building.<\/p>\n After a decade of talks, he says it demonstrates the depth of alignment between the company and the state in delivering PNG\u2019s first integrated lime and cement manufacturing industry.<\/p>\n State nominee Kumul Mineral Holdings Limited (KMHL) has paid US$16.3m for a 13% stake in Central Lime, with an option to buy an additional 5% for US$6.8 million after first quicklime in Q1 CY27.<\/p>\n Under the PDA, KMHL can also acquire up to a 30% interest in Central Cement, whose most recent NPV is US$339 million.<\/p>\n \u00a0<\/p>\n Self-sustaining progress<\/p>\n In an economy running on gas, gold and copper, there\u2019s growing demand for reliable, domestically sourced industrial inputs that meet Tier-1 mining standards.<\/p>\n Newmont Corporation\u2019s (ASX:NEM)<\/a> quicklime offtake agreement to supply its long-standing gold operations in PNG shows how much the economy is evolving.<\/p>\n The agreement in February 2026 cemented Newmont as a cornerstone customer of Pacific Lime, with contracted volumes for one-third of Central Lime\u2019s nameplate production capacity.<\/p>\n At that scale, the deal underpins the commercial development of PNG\u2019s first domestic quicklime manufacturing operation \u2013 and displaces imports.<\/p>\n As the first large-scale commercial commitment to locally produced quicklime in PNG, the agreement reflects Newmont\u2019s support for the buy-local push.<\/p>\n Reduced transport emissions and increased local value add to the ESG and social licence case. But there\u2019s a commercial imperative, too.<\/p>\n For gold major Newmont, the offtake arrangement strengthens the supply chain. It reduces exposure to ructions in international logistics that can drive costs up, which matters more than ever as shipping costs remain elevated.<\/p>\n For PNG, the lime and cement project supports jobs and skills and a new nationally significant industrial capability.<\/p>\n \u201cCement is essential in building our nation. We want to see all our roads built with cement from the limestone resources within PNG,\u201d according to Minister for International Trade and Investment Richard Maru<\/a>.<\/p>\n \u201cAs a country, we should not be importing limestone and cement because we are endowed with limestone resources.\u201d<\/p>\n \u00a0<\/p>\n PNG turns 50<\/p>\n PNG\u2019s Minister for Mining Solen Loifa has signalled mining law reform to make the nation a leading destination for mining investment in the Asia-Pacific.<\/p>\n
