Mining Engineering Salary in PNG: Pay Bands and Tax

Mining engineering salary in PNG: the short answer

A mining engineer in Papua New Guinea (PNG) typically earns about K3,000 to K8,100 a month before tax. That is the middle 80% of pay reported to the Paylab salary survey for the role, viewed on 30 October 2026 (Paylab, mining and metallurgy salaries in PNG). At the Trading Economics rate of 4.49 kina per US dollar on 30 October 2026, that band is roughly US$8,100 to US$21,500 a year.

Those are survey figures for people paid in kina inside PNG. They are not quotes for fly-in fly-out (FIFO) contracts offered to foreign specialists, which are set in each contract and rarely published. This page sets out the survey bands by role, what the kina figure means after PNG salary tax and superannuation, which gold mines are hiring, and how to check an offer. A take-home pay calculator sits in the tax section.

A short guide to the terms used: “gross” means pay before tax; “K” or “PGK” is the PNG kina; “superannuation” is the compulsory retirement saving deducted from a PNG citizen’s pay; and “FIFO” means workers fly to a remote mine for a set roster and then fly home.

Salary ranges for mining roles in PNG

Paylab is a salary survey that asks employees to report their own pay, so its figures are self-reported and change as new answers arrive. For PNG it publishes an 80% band for each role: 10% of respondents earn less than the lower figure and 10% earn more than the upper one. The table below uses the bands shown on 30 October 2026.

Monthly gross pay bands in PNG by role

PGK per month, low and high end of the middle 80% of survey answers

Annual figures are the monthly figures times 12, rounded. The US dollar column uses one day’s exchange rate and will drift as the kina moves; Trading Economics recorded the kina about 5% weaker against the dollar over the 12 months to 30 October 2026 (Trading Economics, USD/PGK).

Two things stand out. First, a mining engineer’s band starts higher and reaches further than the average for the mining and metallurgy group as a whole, which fits a degree-level role with site responsibility. Second, the top of the engineer band (about K8,060) is above the top of the national all-jobs band (about K7,020), so a senior mining engineer sits among the better-paid salaried workers in the country.

Why older salary figures look much higher

Some web pages quote PNG mining engineers at K25,000 to K60,000 a month. Those figures are several times the survey bands above and are not tied to a named survey. They may describe expatriate packages that bundle housing, flights, schooling and hardship pay into one number, or they may be guesses. When you see a figure, ask what it includes, who it covers (PNG citizens or foreign contractors) and where it came from.

Geologist salary in PNG

Paylab does not yet publish a separate PNG band for geologists; its geologist page shows only the national all-jobs range of K1,954 to K7,020 a month. The closest published comparison is the mining engineer band (K3,023 to K8,059), because mine geologists and engineers work side by side on grade control, pit design and reserves at the same sites.

Geology roles on a PNG gold mine usually fall into three groups:

• Exploration geologist: maps rock types, collects soil and rock samples, and logs drill core to find new ore. Work is often in remote camps away from the mine.
• Mine or grade-control geologist: decides which blasted rock is ore and which is waste. “Grade” means how much gold is in the rock, usually given in grams per tonne (g/t); the “cut-off grade” is the lowest grade worth processing.
• Resource geologist: builds the 3D model of the orebody used to estimate tonnes and grade.

Pay for each depends on degree, years of experience and roster, and is set by each employer. If you are comparing offers, ask for the base salary and each allowance as separate kina figures so that you can line them up against the bands on this page.

Mineral processing engineering salary in PNG

Mineral processing (also called metallurgy) is the work of turning ore into a product the mine can sell. At Lihir and Porgera that product is doré, a bar of mostly gold and silver poured on site; at Ok Tedi it is a copper-gold concentrate shipped for smelting (Mineral Resources Authority, ministerial update on the mining sector).

The Paylab bands for processing staff in PNG on 30 October 2026 were K2,727 to K6,686 a month for metallurgists and K2,109 to K5,249 for metallurgy engineers. Plant metallurgists work on crushing, grinding, leaching and gold recovery; recovery is the share of gold in the ore that ends up in the bar. Lihir, for example, recovered 77.1% of the gold in its mill feed in 2025 (Newmont 2025 Form 10-K). Each point of recovery is worth real money to a mine, which is why experienced plant staff are sought after.

Mining engineering salary in PNG per month after tax

PNG taxes salary and wages on a sliding scale. For residents, the first K20,000 of taxable income a year is taxed at 0%. Above that, the rates are 30% up to K33,000, 35% up to K70,000, 40% up to K250,000 and 42% above K250,000. Non-residents pay 22% from the first kina up to K20,000 and then the same higher rates (PwC Worldwide Tax Summaries, PNG personal income tax, viewed 30 October 2026).

Chart

PNG resident salary tax rates by income band

Marginal tax rate, % of taxable income in each band (PGK a year)

PNG has no social security system. Instead, PNG citizen employees pay 6% of gross basic salary into an authorised superannuation fund, and the employer adds 8.4%. These contributions are compulsory for citizens and voluntary for non-citizens (PwC, PNG other taxes). The employee’s 6% comes out of after-tax pay.

Worked example: K5,000 a month

A resident PNG citizen earning K5,000 a month basic, with no allowances, has K60,000 a year of taxable income. Tax is K3,900 on the first K33,000 plus 35% of the next K27,000 (K9,450), so K13,350 a year. Superannuation at 6% is K3,600. That leaves K43,050 a year, or about K3,590 a month in the hand. A non-resident on the same pay would owe K17,750 in tax under the non-resident scale and would usually not pay superannuation.

Use the calculator below with your own figures. It applies the resident scale only, so foreign workers taxed as non-residents should treat the result as an upper limit on take-home pay.

Which PNG gold mines employ the most people

The Mineral Resources Authority lists Lihir and Porgera as PNG’s large-scale gold mines, Ok Tedi as a large copper-gold mine, and Simberi, Hidden Valley and Kainantu as medium-scale gold-silver mines. Most jobs in gold mining sit at these sites and with the contractors that serve them.

K92’s figures show the scale of local hiring at a single underground mine: about 2,150 employees and permanent contractors, rising to about 3,100 people with temporary contractors and casual workers, with PNG nationals making up about 91% of the operational workforce at the end of 2025. Priority hiring from nearby communities is part of its stated policy. Readers looking at life on a large site can also read our guide to working at the Porgera gold mine.

Tolukuma gold mine job vacancies and salary

Tolukuma is an underground gold-silver mine north of Port Moresby in Central Province, owned by Tolu Minerals Limited (ASX: TOK). Tolu reported its most intensive drilling programme at the mine in the June 2026 quarter and restarted underground development on the 1560 Level, with first gold targeted for the first quarter of 2027 (Motley Fool Australia on Tolu’s June quarter, 31 July 2026). In September 2026 the company reported an 81% increase in the Tolukuma mineral resource estimate and again pointed to a restart in early 2027 (ShareCafe, 16 September 2026).

A mine moving from development to production usually hires in stages: underground miners, drillers and geologists first, then plant operators, metallurgists and maintenance staff as the mill restarts. Tolu has not published a pay scale. The survey bands earlier on this page are the best public check for kina offers in these roles, and the minimum wage below sets the legal floor. Vacancies are posted by the company and its contractors; check that any job advertisement links back to the company’s own website before sending documents.

PNG minimum wage: the legal floor

The national minimum wage in PNG rose from K3.50 to K5.00 an hour on 1 January 2026, the first change since the 2016 review (WageIndicator, January 2026). The Minimum Wages Board set further steps to K5.25 in January 2027 and K5.50 in January 2028 (Business Advantage PNG). The Board had been re-established in 2024 with support from the International Labour Organization, which noted that the previous review was in 2016 (ILO, 25 September 2024).

Chart

PNG national minimum wage, scheduled steps

PGK per hour, rate from 1 January each year

At 40 hours a week, K5.00 an hour is K200 a week, or about K10,400 a year. That is below the K20,000 resident zero-rate band, so a full-time worker on the minimum wage pays no salary tax. Entry-level mine labourers and trainees are paid above this floor in most cases, but the rate matters for camp, catering, security and transport contractors who serve the mines.

What moves mining pay up or down in PNG

The same job title can pay very differently from one site to the next. These are the factors that most often explain the gap, and the questions to ask about each.

• Roster and remoteness: most large gold mines are far from towns. FIFO rosters (for example two weeks on, two weeks off) often carry site or remote allowances. Ask whether an allowance is part of base pay, because superannuation is paid on gross basic salary only.
• Citizenship and tax residency: citizens pay 6% superannuation and get the K20,000 zero-rate band if resident; non-residents pay 22% from the first kina. Two people on the same gross pay can take home quite different amounts.
• Underground or open pit: underground mines such as Kainantu and Tolukuma need certified underground miners, ventilation officers and shift bosses. Certificates are a common reason for higher pay within a band.
• Stage of the mine: a mine in production has stable rosters and pay scales; an exploration project or a restart may offer shorter contracts.
• Gold price: high gold prices support hiring and bonus pools, while low prices bring cuts. Mines also budget in US dollars while paying many staff in kina, so the exchange rate matters.
• Benefits outside the payslip: camp housing, meals, flights, medical cover and schooling can be worth a large share of a package. Write each one down with its kina value.

How to check a mining job offer in PNG

1. Split the offer into parts. Ask for base salary, each allowance, overtime rules, bonus and roster as separate lines in kina.
2. Compare base pay with the survey band. Use the role table above. A base below the low end of the band deserves a question; a base above the top end may reflect seniority or a hard-to-fill site.
3. Work out take-home pay. Use the calculator above with your base and taxable allowances, and set superannuation to 0% if you are not a PNG citizen.
4. Check the employer. Confirm the operator of the mine with the company’s own website or annual report before sending personal documents.
5. Ask about safety training and tickets. Site inductions, underground certificates and first aid courses add to your value in the next role.
6. Keep a copy of the contract. Make sure roster, leave, flights and the notice period are in writing.

Where satellite data fits in PNG exploration

Much of PNG’s prospective ground sits under forest on steep slopes, far from roads. Satellite imagery and terrain models help companies narrow down where to send field teams before they commit to sampling and drilling. Farmonaut’s satellite-based mineral detection service maps alteration and structure inside a licence boundary so that targets can be ranked before drilling; licence holders can send a project query or contact the team for a quote.
