Papua New Guinea’s geography has driven innovation in mining logistics, creating operators with unmatched expertise.
When mining executives sit down to calculate the cost of extracting Papua New Guinea’s (PNG) world-class copper, gold and nickel deposits, a significant part of their budgets won’t always be spent on drills, excavators or processing plants. Rather, roughly half of capital costs for establishing new mines in PNG can be spent on roads, power, water, housing and transport.
It’s a stark reality that sets PNG apart from virtually every other major mining jurisdiction. The combination of rugged mountain terrain, dense rainforest, tropical climate and lack of modern infrastructure creates what many would consider a perfect storm of transport challenges.
Yet PNG’s mining sector continues to thrive.
Rather than deterring investment, these challenges have driven innovation and created a generation of operators with expertise unmatched virtually anywhere in the world.
The companies that have learned to move equipment, supplies and ore across PNG’s demanding landscape haven’t just overcome obstacles; they’ve developed solutions that turn apparent disadvantages into competitive strengths.
A maritime backbone
PNG’s geography may lack roads but it does have more than 5000km of coastline across an extensive archipelago and the eastern side of New Guinea island. That is well-served by established maritime networks and infrastructure.
For mining operations, coastal shipping isn’t simply one transport option among many, but often the foundation upon which entire supply chains are built.
The economics are compelling.
A single excavator can weigh 50 tonnes, a haul truck 100 tonnes or more. Mines require cement by the thousands of tonnes, diesel fuel in constant supply, and spare parts ranging from small components to massive mill sections. At these volumes, only maritime transport offers the of capacity and cost-effectiveness mining demands.
Golden Shipping, operating through its subsidiaries PNG Bunkering and Niugini Port Services, has spent more than two decades addressing PNG’s unique logistical challenges. As part of the Rimbunan Hijau PNG Group, the company provides maritime logistics that keep PNG’s resource sector moving, delivering everything from heavy equipment to bulk materials across the country’s vast archipelago.
Golden Shipping manages a diverse fleet including landing crafts, tugs and barges, and tankers. According to shipping manager Edward Soo, each vessel type is selected to handle different cargo requirements and operating conditions.
“Our clients need more than just vessel capacity; they need a logistics partner who understands PNG’s unique challenges with cost-effective solutions,” he said.
The company’s service range spans inland waterways, coastal shipping and offshore maritime operations. Golden Shipping offers ship chartering, marine logistics, fuel supplies, wharf facilities and stevedoring services – an integrated approach that allows clients to coordinate complex supply chains through a single partner rather than managing multiple contractors.
For inland mining operations, this multimodal capability proves essential. Coastal shipping delivers equipment and supplies to port facilities, where they transfer to aircraft, river barges or road transport for final delivery. Maritime transport remains the foundation that makes these complex logistics chains possible.
International shipping specialist Blue Water Shipping entered the PNG market in 2021, bringing global expertise to the country’s maritime logistics sector. The Danish-headquartered firm’s first major contract was with Newmont’s Lihir gold mine, on Lihir Island in New Ireland province. Blue Water currently moves around 15,000 20-foot-equivalent units worth of supplies onto the site each year.
Both companies demonstrate how established coastal shipping networks have become critical infrastructure for PNG’s mining sector, infrastructure that continues to expand as the industry grows.
Taking to the skies
Of course, water-borne transport cannot offer a complete logistics solution itself. Unique to PNG, air transport offers something equally valuable: flexibility and access to sites where no other option exists.
The perception that helicopter services are “prohibitively expensive” doesn’t tell the full story. It’s true that air transport costs more than road or sea freight in other jurisdictions, but within PNG’s transport mix – where roads often don’t exist and building them can take years – helicopters frequently represent the most economically viable option for keeping operations running.
The Tolukuma Gold Mine in the Central Highlands provides an instructive case study.
From the mine’s commissioning in 1995 until 2025, Tolukuma’s operators relied entirely on helicopter transport for fuel, equipment and personnel access.
When road access finally broke through to the site in August 2025, Tolu Minerals estimated it would reduce delivered fuel costs by around 75 per cent.
The significance isn’t that helicopter transport was unsustainable; the opposite was in fact true. The mine operated for decades using helicopter services, and while road access has definitely made things cheaper, it has not instigated an overwhelming change to Tolukuma’s operating model.
Outside of Tolukuma, multiple helicopter service-providers have built specialised capabilities around PNG’s mining sector demands.
These companies offer multiple critical functions to mining operations specifically. They enable exploration in areas where road access may never be economically feasible. They deliver urgent spare parts that keep processing plants running, avoiding production losses that could cost millions. And they transport personnel safely and quickly, particularly valuable when weather closes road access or medical evacuations are required.
Other solutions
Beyond established transport solutions, PNG mining operators are increasingly deploying technology to maximise efficiency and reduce logistics costs.
Digital fleet management systems using GPS tracking and satellite communications allow operators to monitor vehicle and ship locations, fuel consumption, and maintenance needs in real-time. This has the impact of reducing downtime and optimising routes across all modes of transport.
Drone technology is also being explored for small-scale supply deliveries to isolated exploration camps, potentially reducing helicopter dependency for routine light cargo movements.
Public–private partnerships offer additional promise. When mining companies invest in roads that also serve communities, cost-sharing arrangements with government can make these shared infrastructure projects viable, while delivering broader development benefits.
The Connect PNG program, which aims to build 2500km of new roads and improve 14 major corridors by 2027, explicitly seeks private sector involvement, creating potential alignment between mining logistics needs and national development priorities.
PNG’s logistics landscape is unique, complex and certainly challenging. But this hasn’t stopped mining from taking place.
On the contrary, it’s created an industry of highly skilled and creative problem-solvers. Companies that master PNG’s transport challenges develop operational capabilities that can translate to further success in other markets.
The same geography that demands significant infrastructure investment also helps to ensure those investments create lasting value: roads that serve communities, maritime networks that connect regions, and helicopter services that enable access where none would otherwise exist.
As global demand for critical minerals intensifies, PNG’s proven operations, established logistics networks, and generation of experienced operators become increasingly valuable assets. The geology attracted the investment; the logistics solutions will sustain it.
