Kora
Asset
Project information
Description
Principal producing deposit of the Kainantu Gold Mine, a high-grade intrusion-related gold-copper-silver vein system combining the former Kora, Eutompi and Kora North deposits following the May 2017 Kora North near-mine discovery. Comprises two parallel, steeply west-dipping quartz-sulphide vein systems (K1 and K2) plus the linking Kora Link structure, within a mineralized zone more than 2.5 km long, 60-80 m wide and over 1,000 m of down-dip continuity; veins reach up to 10 m in width. Mining is by Avoca and modified Avoca methods transitioning to longhole stoping with pastefill. Approximately two-thirds of the known Kora resource sits within mining lease ML150, with the deposit extending south into EL470 where a mining lease application is required prior to mining. The lode is richer in copper towards the south (Kora South), a priority corridor in the ongoing exploration program toward the A1 porphyry target. Underground drilling continues at Kora, Kora South and Kora Deeps, where 2025 drilling expanded a high-grade dilatant zone.

Judd
Asset
Project information
Description
Producing vein deposit of the Kainantu Gold Mine, subparallel to and approximately 90-150 m east of the Kora deposit, located entirely within mining lease ML150 and accessed from existing near-mine underground infrastructure. The Judd vein system comprises multiple veins from J1W and J1 in the west to J3 in the east across a 60-80 m wide package, with mineralization style similar to Kora (intrusion-related gold-copper-silver quartz-sulphide veins). First significant exploration by K92 was a 2020 bulk sample from the Judd #1 Vein; Judd became a new mining front in October 2021 following promising drilling, development and metallurgical results, and a maiden resource was declared in February 2022. The December 2023 resource update increased measured and indicated ounces by 167% and inferred ounces by 211% versus 2021. Ongoing underground drilling targets Judd, Judd South and Judd Deeps, with 2025-2026 drilling extending the high-grade dilatant zone; Judd North is a 2026 surface exploration target.

Blue Lake Porphyry Project
Asset · Exploration
Project information
As at 1 August 2022
Description
As at 1 August 2022
Wholly-owned copper-gold porphyry deposit located approximately 4 km southwest of the producing Kora and Judd deposits at the Kainantu Mine, within exploration licence EL470. Discovered by K92 in 2017 after identification of a mineralized lithocap; two diamond drill programs totalling 26 holes and 16,474.8 m have been completed at a discovery cost below $1/oz AuEq. The maiden inferred resource of 14.6 Moz AuEq makes Blue Lake the fifth largest known mineralized porphyry in Papua New Guinea by pre-mined contained gold-equivalent ounces, after Golpu, Panguna, Ok Tedi and Frieda River. The deposit is a concentrically zoned tonalite porphyry with a metal-rich potassic core (biotite-K feldspar with chalcopyrite/bornite), an in-pit resource with high-grade core, open at depth, with interpreted dimensions of 1,500 m x 1,300 m x 1,100 m. An amended technical report containing the resource was filed March 31, 2025. Future plans target additional mineralized porphyries beneath a 20 km2 lithocap extending to the A1 copper-gold porphyry target, the company's highest priority porphyry target.

Arakompa
Asset · Exploration
Project information
Description
Near-mine exploration property located approximately 4.5 km from the Kainantu Gold Mine process plant, hosting a historic resource that makes it a high-priority follow-up target. A maiden surface diamond drill program commenced in 2024; first results (February 2024) and subsequent 2025 results confirmed two significant thick high-grade subparallel veins, a southern strike extension and a bulk-tonnage zone expanded by approximately 150 m to the south for a total strike length of approximately 900 m. The fifth set of results (September 2025) significantly expanded the bulk zone and identified a potential porphyry discovery within a 600 m x 600 m copper-in-soils anomaly. Arakompa is a focus of the enlarged $31-35 million 2026 surface exploration program alongside Maniape and Judd North. No current mineral resource estimate is disclosed for the property in this AIF.

How to read this tab
- The tables below list unit codes most often used in the Precious Metals sector for this company. MetalPilot stores contained metal or product in the codes below; grade and tonnage use separate fields. In side-by-side comparison views (stock page Portfolio tab, watchlist By sector), heterogeneous source units are converted to each commodity's preferred display unit (for example Moz Au, kt Cu, MMbbl oil) before summing; the same canonical codes appear in project data.
What the Portfolio tab shows
- The Portfolio tab presents a project-level view of the company's reported assets, built from publicly disclosed information (technical reports, annual filings, MD&A, investor presentations, MRMR / R&R statements, NI 43-101 / NI 51-101 / SEC S-K 1300 / SEC S-K 1200 / JORC / SAMREC / PERC / PRMS / COGEH filings, and similar primary sources).
- Figures are grouped by project type (mining, oil & gas, royalty, stream, processing facility, development, portfolio aggregate) and are shown alongside the headline reserve base, headline production, headline grade / quality, cost benchmarks, estimated lifetime, commercial terms (for royalties / streams), operational capacity (for processing) and a single-figure rating where the underlying data supports one.
- Each data table on the Portfolio tab is followed by ONE Assumptions footnote describing the modelling choices for that table; KPI stat-card assumptions appear in the bottom block instead. All legal and section disclaimers are merged into a single disclaimer list at the bottom of the Portfolio tab.
Concepts in your sector — Precious metals
- Resources vs Reserves. Resources are geological estimates that could one day be mined; Reserves are the subset with a feasibility study and plausible positive economics. Measured → Indicated → Inferred describe increasing geological uncertainty; Proven → Probable are reserve labels from Measured/Indicated. Inferred resources are not convertible to reserves under most codes.
- Grade (g/t) is the headline number on gold/silver pages. High-grade is often above 5 g/t; >10 g/t is bonanza territory; below 1 g/t is bulk low-grade. Open-pit cut-offs are typically lower than underground.
- AISC (All-In Sustaining Cost) is direct cash costs + sustaining capex + royalties + corporate overhead + reclamation, per ounce produced. C1 strips sustaining capex and corporate overhead. Both are non-GAAP and defined differently across issuers.
- By-product credits. Polymetallic deposits credit by-product value against the main metal cost; negative AISC after credits does not mean the main metal is sold below cash cost.
Portfolio tab — table guide
- Portfolio KPIs — company-level headline numbers aggregated from the featured projects (project counts, attributable annual production by commodity, attributable resource base by commodity, last filing date, operator share). USD value lines multiply attributable volumes by the resolved snapshot price.
- Portfolio snapshot — one-screen summary of the portfolio: counts by type and status, country mix, reporting standards used, operator share, primary commodity, attributable annual production summary and attributable resource base summary.
- Mining — one row per mining project, with columns for project name, location, status, primary commodities, production (with rating), reserves & resources (with rating), grade (with rating), costs and estimated lifetime. Multi-commodity projects emit one summary row per commodity.
- Royalty — one row per royalty interest held by the company. Columns cover the underlying project, operator, commodity, commercial terms (rate, type, cap, area-of-interest), attributable production, attributable reserves and estimated lifetime.
- Stream — one row per metal stream held by the company. Each row shows the underlying project, the streamed commodity, the headline stream percentage, the ongoing per-ounce / per-tonne payment, and attributable production / reserves.
- Processing facilities — one row per midstream / processing facility (pipeline, fractionator, LNG train, storage cavern, refinery, smelter, mill, heap-leach pad, CPP, etc.). Columns include nameplate capacity, contracted capacity, feedstock commodities and operational footprint.
- Development — projects in development status or in a pre-production lifecycle phase. The production column is re-labelled 'Targeted production (rating)' to highlight that the figures are plans, not actuals.
- Portfolio Aggregate — a single company-level row used when the company itself publishes a portfolio rollup (e.g. company-wide 2P barrels across all properties).
- Reserves & resources — detail — a leaf-category pivot showing every reserve and resource category disclosed across the projects.
- NPV (grouped) — all NPV rows captured from the filings, grouped by commodity, resource category, development status and pricing case. Each NPV figure is shown with its discount rate, basis (before-tax / after-tax), currency and value scale.
Ownership / Working interest
- Ownership percentage means the company's working-interest share of the asset: its slice of the project before royalties and before government take. It is shown on a 0–100 scale.
- Mines, oil and gas fields, and processing facilities — this is how much of the asset belongs to the company under that working-interest idea. One hundred percent is fully owned; a lower number usually means partners share the rest.
- Royalties and streaming agreements — the percentage is often not the story; what matters economically is usually the royalty or stream rate, shown elsewhere alongside these figures.
- Oil and gas — read this as gross working interest only. Do not treat it as net production or net wells after royalties; when filings distinguish gross from net, that shows up in how the resource numbers themselves are labelled.
- Below 100% — the short summary for each project names other owners and their stakes when the source says who they are.
- NRI vs WI (O&G). Working interest (WI) is the obligation to pay a share of costs; net revenue interest (NRI) is the share of revenue after royalties and overriding-royalty interests. A 100% WI well rarely produces 100% NRI; typical onshore U.S. NRI is 75–87.5% of WI depending on the lease royalty.
- Operator vs non-operator. The operator runs day-to-day operations; non-operating partners pay their WI share of costs but do not run the asset. Some Portfolio rows show operator share where disclosed.
Unit codes, conversion cheat sheets, cost benchmarks (AISC, C1–C3), reporting standards (NI 43-101, JORC, SEC S-K 1300) and resource/reserve category definitions live in the full terminology & units reference.
Each table lists the numeric band for scores 1–5 (production and resource base; grade where applicable for mining commodities) using the same thresholds as project rating stat cards. Only commodities that appear on featured projects for this document are listed.
Gold
Silver
Copper
Copper uses Mlb Cu bands because featured projects include lb-scale contained units on copper rows. Lithium grade uses hard-rock % Li₂O bands unless brine-style extraction or brine units appear on featured projects.
