It means the richest\nmaterial is often the lowest 0.5-2 m of gravel immediately above bedrock.\nOverburden \t3-8 m \tnear zero to 0.2 g/m³\nMiddle gravels \t2-6 m \t0.5-3 g/m³\nSecondary channel / false bottom \tlocalized \t3-10+ g/m³\nBasal pay gravel \t0.5-2 m \t5-20+ g/m³\nBedrock cracks & traps \tlocalized \tpotentially very high\nIllustrative vertical section\nExploration priority: identify the thalweg / deepest channel\nposition and confirm basal pay thickness with physical\nsamples.\nSources: Gold Placer Geological Summary Tipuani-Mapiri; Mapiri Gold Estimate.\n\n-- 10 of 16 --\n\nLAYERED RESOURCE PICTURE\nA layered low case explains the upside without overstating grade\nDIGIX, INC. | GoldnDigital | Mapiri Geological Update \t7\nA realistic model can assume a broader mineralized interval while still preserving the geological fact that the highest\ngrade is expected near bedrock.\nExample 5 m vertical model\nUpper 3 m at 2 g/m³\nBottom 2 m at 8 g/m³\nBedrock contact / traps\n4.4 g/m³\nweighted blended grade\n75.3k oz\ncontained gold\n~64k oz\nat 85% recovery\nWhat this shows\nAssuming only 2 meters of pay can understate ounces if a broader 5-\nmeter mineralized channel exists. But assuming the entire 5 meters\ncarries basal-grade gold would be aggressive until sampled.\nSource: Mapiri Gold Estimate layered scenario.\n\n-- 11 of 16 --\n\nWHAT THE GEOLOGY SAYS\nRegional placer mechanics support a targeted mining approach\nDIGIX, INC. | GoldnDigital | Mapiri Geological Update \t8\nCoarse basal gravels\nThe report describes the highest gold contents in basal sediments of the\nlower sequence, with largest and heaviest particles concentrated toward\nthe bottom.\nRepeated channel events\nPay gravels can occur at the bottoms of individual channels, not only at the\nfinal bedrock contact - creating stacked targets.\nOperational logic\nA surface anomaly matters most where it intersects a buried channel axis\nand a reachable basal pay horizon.\nFigure source: sedimentology, gold contents, and grain-size relationship in Tipuani riverbed and lower terrace deposits.\nSource: Gold Placer Geological Summary Tipuani-Mapiri.\n\n-- 12 of 16 --\n\nUPSIDE FRAMEWORK\nLarger upside potential with existing footprint, not just higher grade\nDIGIX, INC. | GoldnDigital | Mapiri Geological Update \t9\nsatellite/fine-gold anomalies expand the mineralized footprint beyond 10.64 ha, the total\ncontained ounces could increase materially - even at moderate grades.\nAverage grade \tGold / hectare at 2 m thickness\n1 g/m³ \t643 oz\n3 g/m³ \t1,929 oz\n5 g/m³ \t3,215 oz\n10 g/m³ \t6,430 oz\n30 g/m³ \t19,291 oz\nWhy confirmation matters\nAt 5 g/m³ over 2 meters, every confirmed hectare adds roughly 3,215\ncontained ounces before recovery losses.\nWhat still must be proven\nThe anomaly map does not determine depth, thickness, grade, or\nwhether yellow detections are actual gold-bearing gravel. Calibration\nsamples are required.\nBest interpretation today\nYellow / fine-gold coverage should be described as a target layer for\ntesting - not as a measured 30 g/m³ grade.\nSource: Mapiri Gold Estimate working document.\n\n-- 13 of 16 --\n\nNEXT TECHNICAL WORK\nValidation plan: convert anomaly maps into a mineable pay model\nDIGIX, INC. | GoldnDigital | Mapiri Geological Update \t10\nThe first-stage program will establish bedrock depth, pay thickness, grade continuity, and a calibrated relationship between map\nintensity and actual sample grade.\n1 \tSurvey \tAccurate ground elevations and control grid.\n2 \tCross-cuts \tTrenches / holes across red and orange corridors, perpendicular to channel direction.\n3 \tBedrock confirmation \tContinue each trench or hole until competent bedrock is reached.\n4 \tBulk samples \tSample every layer, bottom 2 m, final 0.5 m, and bedrock cracks.\n5 \t3D model \tBuild bedrock-depth, pay-thickness, grade-thickness, and paleochannel maps.\nPriority metric\nGrade x Pay Thickness x Channel Area\nSource: Mapiri Gold Estimate validation program.\n\n-- 14 of 16 --\n\nPOSITIONING\nPurchase-ready conclusion\nDIGIX, INC. | GoldnDigital | Mapiri Geological Update \t11\nThe Mapiri work should be presented as a high-potential placer target inside a historically\nproductive basin, with a disciplined preliminary model and an immediate validation path.\n1 Strong geological support \tRegional studies validate the Tipuani-Mapiri basin as a highly mineralized placer setting with\npaleochannels, terraces, and reworked river deposits.\n2 Concentrated pay logic \tHighest grades are expected in basal gravels, channel bottoms, bedrock contact zones, and localized\nveneros.\n3 Defensible modeling case \tUse 4-5 g/m³ blended and 8-12 g/m³ for red corridors until trenches and bulk samples calibrate the map.\n4 Clear next proof point \tConfirm bedrock depth, pay thickness, and sample grade across the red/orange corridors to convert targets\ninto a mineable model.\nCurrent framing: high-quality exploration target with meaningful preliminary contained-ounce scenarios; not a formal reserve or resource until field validation is complete.\nSources: Gold Placer Geological Summary Tipuani-Mapiri; Mapiri Gold Estimate; prior GoldnDigital buyer presentation style.\n\n-- 15 of 16 --\n\nAPPENDIX\nSource material\nDIGIX, INC. | GoldnDigital | Mapiri Geological Update \t12\nPrimary inputs used\n• Gold Placer Geological Summary Tipuani-Mapiri\n• Mapiri Gold Estimate working document\n• Prior GoldnDigital buyer presentation structure and visual language\nKey limitations\n• The intensity map is not an assay map.\n• Mapped anomalies require trenching, drilling, and bulk sampling.\n• Contained ounce scenarios are preliminary and exclude recovery, dilution, mining losses, and accessibility constraints.\n• Any reserve/resource statement would require formal field validation and technical reporting.\nPurpose: internal / investor presentation summary of geological support and preliminary modeling framework.\nNote: This deck is a presentation summary, not a technical report or NI 43-101 / JORC reserve statement.\n\n-- 16 of 16 --\n\n","numPages":16,"title":"GOLDN Update June 2026","id":"goldn-update-june-2026"}
