Woyla Project – UAV Aeromag Survey Update
Far East Gold Ltd (‘FEG’ or ‘the Company’) is pleased to announce the results from the recently
completed Unmanned Aerial Vehicle (UAV) Photogrammetry, Aeromag and LiDAR survey at four
epithermal prospect areas of the Woyla Copper Gold Project. Interpretation of the survey data has
identified numerous magnetic anomalies and structural features that provide the Company with
a much enhanced ability to define areas of alteration related to mineralisation and important
structural controls of the epithermal veins and breccia targeted by drilling.
Additionally, the Company has completed establishment of a remote fly camp and has now commenced
the UAV Photogrammetry and Aeromag survey over approximately 1,500 ha of the Beurieung porphyry
prospect area located in the south of the Woyla tenement.
HIGHLIGHTS
The Company has completed a combined 391 line km UAV Photogrammetry, Aeromag and LiDAR
survey over the Rek Rinti, Aloe Eumpeuk, Kareung Reuboeh and Aloe Rek epithermal prospect areas.
The Aeromag survey was completed at 50m line spacing and the LiDAR at 160m line spacing
covering an area of approximately 1,300 Ha. Refer to ASX release 4 October 2023.
The results from the Photogrammetry survey will serve as part of the environmental baseline prior to
future mining operations. The LiDAR survey has provided detailed topographical information for these
epithermal prospect areas that can be used to determine the volume of material that could be mined.
This information is necessary for the Company’s maiden JORC resource estimate for the project.
Preliminary interpretation of the Aeromag and LiDAR data has identified a number of magnetic
and structural features. These include:
•
An approximately 1km long by 200m wide, east-west oriented, low magnetic anomaly
that is coincident with the trend of the high grade Agam Zone at Rek Rinti which has
returned a drilled intercept of 2m of 24.7 g/t Au and 194.8 g/t Ag in hole RRD004. The
broad area of intense low magnetics suggests the occurrence of magnetic destructive argillic
alteration which occurs adjacent to the epithermal quartz veins. This infers possible
extension of the Agam quartz vein/breccia zone and the potential for further contained
high grade gold and silver mineralisation. The low magnetic anomaly will be tested as part
of the ongoing Phase 2 drill program.
•
Delineation of several circular features that may reflect ancient caldera rims. Such features
could have been important as locii for porphyry emplacement and development of proximal
epithermal vein systems. This includes delineation of a circular feature at Kareung
Reuboeh that is 2km across and coincides with two newly identified epithermal veins.
•
Identification of a very intense low magnetic anomaly at the Aloe Rek prospect area, which
is yet to be drilled by the Company. This magnetic anomaly coupled with previous high
grade surface samples suggests a robust fluid system with the potential for high grade
mineralisation is present at Aloe Rek.

UAV Survey Results & Rek Rinti Expanded Drilling Program
Figure 1: 3D orthophoto of the Rek Rinti prospect area derived from the LiDAR survey. Image shows the surface
extent of defined quartz vein zones (in red) and the locations of planned Phase 2 drill holes (P2X). Previous holes
completed as part of the Phase1 and 2 drill programs are shown in yellow. Interpreted magnetic linears and areas of
low magnetics are also shown (refer to Figure 2). The locations of current artisanal mining sites are indicated by the
blue tarp roof coverings.
As indicated on Figure 1 there are 6 holes planned for the Phase 2 drill program that have been defined
from the results of the UAV survey:
-
One hole (P2X4) will test for depth extension of high-grade Au intersected in the Rame vein by
RRD003 (2m of 30.9 g/t Au from 191m). Refer to ASX release of December 13, 2022.
-
Another hole (P2X3) will test the high-grade Au mineralisation intersected in holes RRD019 and
RRD020.
-
The additional 4 holes will test zones of low magnetics along trend of the Rame vein to the
southwest (P2X5,6) and east of the Agam zone (P2X1,2). Refer to Table 1 and Figure 2. Such
areas are interpreted as reflecting the occurrence of pervasive, magnetite-destructive, argillic
alteration which commonly occurs adjacent to low-sulphidation epithermal-type quartz veins. A
review of historical surface rock sampling indicates that high-grade Au assays occur within each
of the low magnetic target areas.

Beurieung Prospect Area – Porphyry target
The Beurieung prospect area to the southeast of Aloe Rek continues to be a focus of detailed mapping
by the Company (Figure 4). This area is considered prospective for high-sulphidation and
porphyry copper type mineralisation associated with one or more buried porphyry systems.
The Company has recently commenced an approximately 100 line km UAV Photogrammetry and
Aeromag survey at 200m spacing covering 1,500 Ha in the Beurieung porphyry prospect area. This work
is expected to be completed by the end of 2023 and will form the basis of future field mapping in the new
year to determine the size and scale of the Woyla project’s copper-gold porphyry prospect.
Previous exploration by Barrick and Newcrest identified porphyry-related veins and alteration. The
Company has confirmed the occurrence of sheeted quartz-sulphide veins with disseminated pyrite and
chalcopyrite within altered andesite volcanics. Historical channel sampling by Barrick in 1997 across the
quartz-sulphide veins returned 40m @ 0.13% Cu and 0.12 g/t Au. Along the river about 100m south of
the area channel sampled, rock float of altered diorite (chlorite-sericite-magnetite) with quartz stockwork
veins was found. The source is unknown.

In the Dolok prospect area in Lower Beurieung, Newcrest (1998) reported a 20m wide zone of veined
and silicified andesite containing silica, alunite, with illite-smectite and up to 1% disseminated pyrite.
Petrographic studies identified the rock as a pervasively leached and altered porphyritic andesite with
diaspore, alunite and pyrophyllite overprinted by late stage kaolinite/dickite. This alteration assemblage
is characteristic of that found within high-sulfidation (HS) gold-copper systems. About 400m to the north
of there, a hematitic quartz-breccia vein zone is exposed (Rayangga Vein) that may share the same
structure as the quartz-alunite vein/silicified zone.
The Company has initiated a program of detailed mapping and surface sampling within the Beurieung
area to confirm and define the distribution of porphyry-type alteration and mineralisation. This work will
be important for interpretation of the UAV magnetic survey and delineation of drill targets.
UAV Magnetic Survey
Area
Figure 4: Map of Beurieung prospect area shows locations of porphyry-related type mineralisation as reported by Barrick and
Newcrest. The planned area of UAV magnetic survey is shown. The 3D magnetic inversion model as interpreted by the
Company has defined several high-magnetic anomalies considered by the Company as porphyry targets. The distribution of
argillic alteration (yellow) and an area of advanced argillic alteration in Lower Beurieung are indicated. The occurrence of the
latter adjacent to a high magnetic body suggests potential for a porphyry-related high-sulphidation (HS) type system.
