The Kainantu gold district in northeast Papua New Guinea (PNG) is rapidly gaining recognition as one of the most highly mineralized gold-copper regions globally. As we lead gold exploration projects across these promising terrains, our team at Farmonaut brings attention to breakthrough sampling, advanced surface geochemistry targeting, and modern analysis techniques fueling drill target identification in this district.

With the latest update from South Pacific Metals Corp. (SPMC), a new chapter unfolds at the Anga Project—this progress confirms key gold anomalism zones, validates multiple prospects east of Irinke, and propels sophisticated exploration activities through highly organized soil sampling and analysis, rock chip sampling, and stream sediment sampling. In this in-depth report, we analyze the 5 key sampling results and how these efforts are revolutionizing gold discovery in Kainantu.

We also integrate cutting-edge satellite-based and AI-powered agricultural technologies, outlining how precision tools like those offered through the Farmonaut platform are transforming resource and environmental management for sustainable development—critical alongside mining operations.

Industry Trends: Gold Exploration Projects & Innovations

Global gold exploration projects have surged in technological adoption, particularly in districts like Kainantu where layered geology and complex mineralized systems demand more precise targeting. Our current era is marked by:

• Enhanced sampling techniques— with a focus on soil, rock, and stream sediment analysis for robust anomaly detection.
• Geochemical studies leveraging machine learning and advanced laboratory instruments to detect trace elements and pathfinders within vast areas.
• Structural mapping in exploration— digital terrain models and field mapping apps accelerate structural studies, connecting alteration zones, intrusive bodies, and hydrothermal features with drill-ready targets.
• Data-driven targeting— integration of historical and fresh datasets to refine exploration drilling locations quickly.

The Kainantu region exemplifies these trends, with SPMC’s Anga Project utilizing advanced programs to systematically unlock hidden gold systems—backed by ALS Geoanalytics and robust technical oversight.

Breakthrough in Sampling: Overview of Kainantu’s 5 Key Results

The basis of advanced gold exploration is the collection and rigorous analysis of representative soil, rock, and stream sediment samples across the most promising areas. SPMC’s newest surface geochemistry targeting effort, powered by ALS Geoanalytics, has produced five crucial sample results, dramatically refining the drill target identification process.

Significantly, the integration of geochemical indicators for discovery—including elements known to track gold mineralization (e.g., Bi, Sb, Te, Ag, Mo, Cu, Zn, Pb)—has clarified vectors to additional mineralized areas extending from the Irinke Prospect eastwards toward new, previously under-explored districts like Binano North and Golkona.

Our approach emphasizes:

• Targeted sampling grids (up to 250 grid soil samples at 50 x 50 m spacing)
• Full integration of historical and current geochemical datasets
• Correlation of geophysics, geochemistry, and field structural mapping
• Iterative surface sampling and laboratory analysis

Upon reviewing these five pivotal samples, immediate on-the-ground programs have commenced, and new areas are being readied for further drilling.

Technological Advancement: Surface Geochemistry Targeting

Modern gold exploration projects depend on more than just manual prospecting and hope—they are anchored in targeted data gathering, rapid interpretation, and fast, feedback-driven field operations. ALS Geoanalytics’s involvement has brought advanced geochemical modeling and interpretation capabilities:

• Multielement analysis—using 4-acid digestion and ICP-OES to read the chemical signature of each sample.
• Fire Assay (Intertek Code FA25/OES)—used for gold with atomic absorption finish, enabling low detection limits (as low as 0.01ppm).
• Quality Assurance— insertion of certified reference material, duplicates, and blanks for quality control; cross-checking all samples above 1ppm Au.

Our comprehensive integration of multi-element assays has confirmed the presence of K92’s Arakompa-like geochemical signatures within the new prospects east of Irinke.

This multi-tiered approach enables efficient drill target identification, reducing both risk and cost while maximizing the chances of significant discovery.

Soil Sampling, Rock Chip Sampling & Stream Sediment Analysis in Gold Exploration

A modern exploration campaign incorporates various sampling techniques, each providing unique insights into the mineralized gold district:

Soil Sampling and Analysis

We employ soil sampling to examine c-horizon soils, processed to <2mm size before shipment to the ITS (PNG) Ltd. (Intertek Laboratory) in Port Moresby. The samples are assayed for gold and pathfinder elements using aqua regia digestion and mass-spectrometry finish (AR01/MS). This process is essential for the following reasons:

• Detecting subtle soil gold anomalies—often missed by other methods, providing vectors for further exploration.
• Geo-spatial mapping—dense sampling grids enable us to spatially model gold anomalism and prioritize field activities.

Certified reference materials, duplicates, and blanks are consistently used for robust QA/QC.

Rock Chip Sampling

Our field geologist selects and collects rock chips from outcrops and float material, focusing on areas with visible alteration or mineralization. These are then assayed by fire method, with any result above 1ppm Au being re-checked. Notably, rock chip assays at Irinke returned up to 3.68 g/t Au, strengthening our confidence in the mineralized system east of Kainantu.

Stream Sediment Sampling

We supplement soil and rock sampling with comprehensive stream sediment sampling, particularly in rugged, heavily vegetated, or alluvial areas. Collecting and sieving natural sediment from streams at trap points, our program enables us to:

• Rapidly screen large catchment areas for gold anomalies
• Identify upstream sources and prioritize further surface investigation

Assays use fire assay with an AAS (Atomic Absorption Spectra) finish and a detection limit of 0.01ppm gold.

Exploring the Major Prospects and New Target Areas

Analysis of current and historical data—combined with fresh reconnaissance—has identified several significant prospects in the Kainantu district:

1. Irinke Prospect

Situated only 1,500m from K92’s processing plant and 3 km along strike from the Arakompa discovery, Irinke is hosted by metasediments intruded by diorite. Soil anomalism and high-grade rock chip assays have verified a highly mineralized system. Geophysics links Irinke’s major structures and alteration patterns closely with those of K92.
Target Areas A, B, and C within this prospect (see referenced figures) have become the focus of new, closely spaced surface sampling and structural mapping—each step aimed at sharpening drill target identification.

2. Binano North (Irinke Extension to NE)

Located approximately 1 km east of Irinke, Binano North’s mapped metasediments and intrusives, strong pathfinder element anomalies, and visible hydrothermal alteration point to a potentially extensive, untapped system. Notably, pathfinders such as Bi-Sb-Te-Ag-Mo-Cu-Zn-Pb show strong presence here. We have conducted grid soil sampling (250 samples, 50x50m) to bring this area to drill readiness.

3. Golkona and Golkona South (Irinke Extensions East)

With a substantial (750x750m) area of gold in soils exceeding 10 ppb (and up to 70 ppb), Golkona’s NE-SW structure ties into the Maniape vein system of K92 Mining. Golkona South’s strong magnetic and conductivity anomalies, found by MobileMT survey, (N1 anomaly) are only just beginning to be sampled systematically, opening up further discovery opportunities.

4. Other Targets on the Anga Project

Several additional targets—immediately adjacent to major gold operations—have been mapped and will soon undergo closely spaced soil and structural mapping campaigns, expanding the frontiers of the Anga Gold-Copper Project.

This broad, systematic approach identifies potential across 461 km² of highly prospective ground contiguous with K92 Mining’s district-scale operations.

Understanding Geochemical Indicators for Discovery

Central to our success in gold exploration are geochemical indicators for discovery. By analyzing over 200 multi-element indicators, our technical teams pinpoint not only the presence of gold but the vectors and halos associated with significant gold mineralization.

• Bismuth (Bi), Antimony (Sb), Tellurium (Te)—commonly linked with gold in magmatic-hydrothermal systems such as those in K92’s Arakompa vein; their anomalous concentrations flag areas for detailed follow-up.
• Copper (Cu), Molybdenum (Mo)—Associations here suggest the proximity to gold-copper porphyry-style deposits, especially alongside NE-SW structures tied to historical mining trends.
• Silver (Ag), Lead (Pb), Zinc (Zn)—These support interpretation of polymetallic systems and aid in identifying the full economic potential of a discovery.

Through a combination of surface geochemistry targeting, laboratory-based multi-element analysis, and closely spaced sampling, we have mapped anomalous zones that had previously eluded traditional prospecting.

Advanced Drill Target Identification & Structural Mapping in Exploration

Drill target identification, particularly within the Kainantu mineralized gold district, relies heavily on understanding the geological architecture. Our programs combine:

• Surface sampling—targeted soil, rock chip, and stream sediment samples
• Field mapping—identifying major structures, alteration zones, and intrusive contacts, with digital mapping tools used for efficiency
• Geophysical analysis—using magnetic/conductivity data (e.g., MobileMT survey for Golkona South’s N1 anomaly)
• Cross-referencing with geochemical halos—to optimally locate drill collars and prioritize drilling programs

By integrating these approaches, we significantly reduce both exploration cost and risk while accelerating progress from anomaly to discovery. Our closely spaced sampling and ongoing laboratory analysis provide the actionable intelligence needed for targeted, successful drilling.
