Adyton Resources Corporation’s (TSX-V: ADY) maiden drilling program of five diamond holes (1,982m) at its 100% owned Feni Island Copper Gold Project has returned significant gold intersections.
All five holes intersected zones of gold, with three holes returning significant intersections:
Adyton Resources President, Executive Chairman and CEO, Mr Frank Terranova, said the results confirmed the continuity and extensions to the existing gold Inferred Resource.
“The presence of higher-grade gold zones is very encouraging and will be a target in future drilling programs,” Mr Terranova said.
“Copper in the system is also confirmed, and more work is needed to test the copper porphyry potential identified from recent 3D Induced Polarisation (IP) modelling, particularly at depth.”
Located in a Tier 1 region along a mineral belt containing the world class Simberi, Lihir, and Panguna gold and copper projects, Mr Terranova said the model at Feni was for a “Lihir-style” epithermal gold overprint on a deeper porphyry copper system.
“The geological setting and mineralisation types are very similar between Lihir and Feni,” Mr Terranova said.
”With all five holes in this initial program intersecting gold mineralisation, the program has reinforced our belief that the Feni Project has significant potential for a large scale, low sulphidation epithermal gold project similar to the Lihir and Simberi styles of mineralisation. The program has highlighted the potential for a significant discovery to be made in the 1.5 km long Kabang structural corridor.”

Drill Program Overview
An initial five hole drill program was completed in September at Feni, totalling 1,962m, testing the highly prospective Kabang mineralised corridor for continuity and extensions of the shallower (0-250m) Lihir-style epithermal gold zone and deeper porphyry copper-gold target.
Holes ADK001, ADK002 and ADK003 (see Figures 2 and 3) were drilled at the southern end of the Kabang corridor (see Figure 2) testing for shallow epithermal gold in the top 200m and deeper copper-gold porphyry potential.
The holes were drilled on average to +400m depth testing the deeper parts of the system. ADK001 and 003 intersected long runs of gold mineralisation which is very encouraging, confirming the potential of the Kabang system. ADK002 intersected long runs of low-grade gold including 10m (45 – 55.0m) @ 0.60 g/t Au within a syenite intrusive.
In all three holes significant pyrite (“pyrite halo”) was intersected which would explain the IP modeling, with strongest mineralisation being encountered in the brecciated margins to the intrusive. Based on the results of the first three holes at Kabang, clearly further drilling is warranted to extend the mineralised zones along the structural corridor.
Holes ADK004 and 005 (see Figures 2 and 4) were drilled to test continuity of mineralization further to the north-east 500m from the first three holes. This area is covered by 70m of younger cover (volcanics, epiclastics and tephra). Beneath the younger cover from 72m depth, ADK004 intersected strong Au mineralisation within hydrothermal breccia. The breccias are phyllic altered, silicified, with strong sulphide (pyrite and arsenopytite) mineralisation up to 10% as breccia fill, stockworks and veining.

Note the prospective corridor is > 1.5kms long, lightly drilled, and under younger volcanic cover at the northern end which has hindered previous exploration efforts.
Hole ADK001 from surface to 200m intersected a highly brittle fractured / brecciated fine-medium grained syenite intrusive with pervasive phyllic alteration with 2-3% fine grained disseminated and fracture fill pyrite – arsenopyrite – silica – sericite-mineralization with an observed late injection of silica – pyrite infilling and cementing cavities and fractures. From 180m to the end of hole a phyllic altered intrusive was cored with zones of potassic alteration observed, with fracture fill of pyrite – arsenopyrite and silica sericite.
From surface to 145.8m this hole intersected a significant long-run of gold mineralisation of 144.80m (1.0 – 145.8m) @ 0.8 g/t Au, including 42.70m (48.3 – 91.0m) @ 1.33 g/t Au; 28m (63.0 – 91.0m) @1.60 g/t Au and 5m (70.0 – 75.0m) @ 2.96 g/t Au and a shallow copper intersection of 16m (7.0 – 23.0m) @ 0.3% Cu.
ADK002 (Figure 2) targeted the centre of the remodelled IP target, and while intersecting similar lithologies to hole 001, intersected narrow zones of lower grade gold mineralisation, the best being 10m @ 0.6 g/t Au between 45.0 to 55.0m. This hole is interpreted to have drilled down the core of the syenite intrusive.
ADK003 was a turnaround from hole 001 and intersected four zones of epithermal gold within a long low grade interval (134m @ 0.5 g/t) of 2m (55.0 – 57.0) @ 1.36 g/t Au; 3m (61.0 – 64.0m) @ 1.16 g/t Au; 6m (93.0 – 99.0m) @ 0.96 g/t Au and 15m (124.0m – 139.0m) @ 1.26 g/t Au.

Holes ADK004 and 005 were drilled further to the north-east along the structural corridor, approximately 500m from the first three holes, and as such they represented a “step-out” to get a better understanding of the mineralisation further along the Kabang structural zone (Figure 2).
Hole ADK004 Hole ADK004 drilled 500m north of the first holes intersected 84.10m (72.0 – 156.1m) @ 0.97 g/t Au, including 10m (74.0 – 84.0m) @ 1.41 g/t Au; 15.60m (91.0 – 106.6m) @ 1.40 g/t Au; 4.60m (151.5 – 156.1m) @ 2.03 g/t Au and 1m (335.0 – 336.0m) @ 5.24 g/t Au.
Significantly, from 151.5 to 155.1m down-hole a zone of massive sulphide mineralisation was drilled with a significant gold intersection of 4.60m (151.5 – 156.1m) @ 2.03 g/t Au and visible chalcopyrite. This zone is significant in the context of structurally controlled higher grade zones that are the focus of the drilling program. The zone is marked by sulphide flooding with pervasive pyrite, pyrrhotite, chalcopyrite, arsenopyrite and magnetite which make up 30 – 40% of the interval. Visual chalcopyrite was observed with assays for copper still awaited. Below the massive sulphide-zone, the hole passed into phyllic altered syenite / diorite porphyry to the end of hole at 394.6m.
ADK005 intersected younger cover to 104m, beneath which a zone of hydrothermal breccia / syenite porphyry with phyllic / argillic alteration associated with sulphide mineralisation to 188m, after which the hole passed into a dacite / andesite dyke. The hole was terminated at 231.5m as the short, initial drilling program was closed out.

Note the mineralization is open along strike, at depth and between the two zones of drilling. Moving to the northwest the mineralisation is covered with a younger volcanic (tephra / trachyte) cover.
Figure 4 is a long section perspective along the Kabang zone, and shows that the deposit is open along strike, at depth, and importantly, between the currently drilled areas as the mineralisation becomes covered by younger volcanic cover progressing to the north.
With all five holes in this initial program intersecting epithermal gold mineralisation, the Kabang Prospect has significant potential for a fast-track development into an advanced project for low sulphidation epithermal gold mineralisation associated with arsenopyrite similar to the Lihir and Simberi styles of mineralisation.
This initial drill program has clearly confirmed the potential for the Kabang-mineralised corridor to host a significant “Lihir-style” gold deposit. The next drilling program will be directed towards better understanding the structural controls, targeting the higher-grade zones, testing the depth extent of the epithermal gold zones, and understanding the distribution of the deeper porphyry copper with the dual objectives of significantly increasing the resource base and upgrading the resource classification.
The Feni Island Group lies at the southeast end of the 250 km long Tabar-Lihir-Tanga-Feni alkalic volcanic island chain, which is largely Pliocene-Pleistocene in age. The chain lies 40 – 60 km off the east coast of New Ireland, PNG.
Ambitle Island is the larger of the two islands comprising the Feni Island Group. It is dominated by Ambitle volcano, which is a collapsed stratovolcano (2 – 8 million years old) built on a basement of early Tertiary sediments. The crater rim is interpreted as a collapse-structure, of gravity-induced failure of the southwest flanks of the Ambitle crater, as opposed to a large caldera structure. It is composed of alkalic mafic to intermediate volcanics and high-level alkalic intrusives, such as monzonites and syenites.
The cone of Ambitle volcano is comprised mainly of vesicular lavas, pyroclastic and epiclastic rocks. The lavas are intermediate in composition and strongly undersaturated, including phonolites, alkali basalts, basanite, trachybasalt and trachyandesite.
The main style of mineralisation on Ambitle Island is low-sulphidation epithermal gold mineralisation associated with quartz veining and sulphide mineralisation (e.g. pyrite, chalcopyrite, arsenopyrite). The gold mineralisation is associated with the Matangakaka Intrusive Complex, which lies at the southern margin of the Ambitle volcanic crater.
The focus of the initial drilling program at Kabang was to test both the shallow epithermal gold zones and deeper porphyry copper potential. The program was focused in and around the Kabang Prospect to test deeper extensions to previous drilling targeting the IP models that are interpreted to indicate a poorly tested chargeable body at depth underneath the shallower epithermal Kabang mineralisation.
The gold mineralisation identified at Kabang is open in all directions with the potential for a deeper copper-gold mineralised system below the gold mineralisation at Kabang and elsewhere on the tenement. There are multiple prospective gold and copper-gold targets, with limited or no drill testing undertaken to date, that demonstrate the potential to significantly grow the current mineral resources for the Feni Project.
