Golden Birch Confirms Daru–Araboro as Third Priority Prospect at Keveri Project
Golden Birch Has Three Priority Prospects to Evaluate at Keveri – Omu, Waki & Daru-Araboro
Timmins, Ontario (April 15, 2020) - Golden Birch Resources Inc. (CSE:GBRX) (“Golden Birch” or the “Company”) is
pleased to confirm the advancement of the Daru- Araboro target to prospect status (“Daru-Araboro Prospect” or
“Daru-Araboro”) and provide information for all technical data generated by the Company at Daru-Araboro.
Highlights of the Daru-Araboro Prospect
● Golden Birch recognised Daru-Araboro as a potential prospect, given its strategic location near
the intersection of key structural features being the main NW -SE Keveri Fa ult and northeast
structures;
● Historic reconnaissance exploration in 1990 by Highlands Gold Ltd . discovered a quartz-
sulphide rock float in Araboro Creek assaying 1.35% copper (“Cu”) and 0.14 g/t gold (“Au”) (Mt
Suckling Exploration Report, Lindley et al 2012);
● Golden Birch geologists carried out initial exploration at Daru-Araboro Prospect in late 2018;
● Follow-up exploration by the Company geologists in early 2019 included traversing of creeks
which uncovered multiple rock float samples with visible copper mineralization;
● Exploration to date has yielded best results of 8.86% Cu and 1.24 g/t Au in separate selective
rock float samples with best Cu results from selective in situ outcrop of 1.64% Cu;
● Exploration at Daru-Araboro is at an early stage and assay values from in situ outcrop and rock
float samples are selective in nature and are not representative of the overall prospect area;
● Further work is required before a representative grade for copper and gold can be determined
for Daru-Araboro;
● Daru-Araboro Prospect has yielded anomalous copper and gold results in multiple selective in
situ outcrops and rock float samples over an area of approximately 1.0 kilometre (“km”) north-
south by 1.0 km east-west; and
● Wide-spaced, reconnaissance soil survey yields multiple anomalous and coincident copper,
gold and molybdenum (“Mo”) values.
Alan Martin, President of Golden Birch states, “ I am excited that our exploration team has advanced the Daru -
Araboro Prospect from grass roots stage to our third priority prospect in our pipeline after Omu and Waki. Daru -
Araboro was highlighted as a potential prospect of merit because of its location near the intersection of key structural
features. It is very encouraging to see that our targeting methods are yielding positive results. The addition of Daru-
Araboro as a priority prospect means the Company has multiple opportunities to create value for its shareholders.
The Omu, Waki and Daru -Araboro Prospects have several characteristic s of Tier 1 Cu -Au deposits in Papua New
Guinea. The exploration results at Daru-Araboro are at an early stage and not representative of the entire project.
Further exploration is required to determine grade and tonnage.”

Figure 1: Location of copper-gold targets within the Keveri Project being explored by Golden Birch. The Daru-Araboro
Prospect is located approximately 12 km east of the Omu prospect (the “Omu Prospect”). Of particular note are the
northeast (NE) transfer structures which form pa rt of the overall Dimidi Trend and the northwest -southeast (NW-
SE) “arc-parallel” Keveri and Nonia Faults (Mt Suckling Exploration Report, Lindley et al 2012).
Exploration at Daru-Araboro
Geological Mapping
The Daru -Araboro Prospect was initially targete d because of the presence of circular and arcuate features (Mt
Suckling Exploration Report, Lindley et al 2012) which were located near the intersection of the regional NW -SE
Keveri fault and northeast structures parallel to the Dimidi Trend (Figure 1). Historic prospecting and reconnaissance
exploration were carried out by Highlands Pacific Ltd . in 1990 and Papuan Precious Metals Corp in 2010. Golden
Birch visited the Daru -Araboro area in late 2018 confirming the presence of visible copper mineralization in rock
float in Daru and Araboro creeks.
Golden Birch geologists carried out preliminary geological mapping at a scale of 1:5000 in early 2019. This work
covered an area of 27 line-kms.
The outcome of the geological mapping produced geological fact and interpretive maps (at 1:5000 scale). The future
exploration program may extend the geological mapping in the east and southeastern part of the prospect due to
the presence of several encouraging anomalies (see Figures 2 and 3).
A total of 120 selective rock samples from in situ outcrops (65 samples) and floats (55 samples) were obtained from
the Daru-Araboro prospect for analy sis. Twenty-three rock samples of selective insitu float and outcrop returned
assays of over 0.1% copper. Many of these rock samples are located within the central part of the Daru -Araboro
Prospect (Figure 2). Ten of the rock samples returned assays of over 1% Cu with the highest being 8.8% Cu. Seven
rock samples returned over 0.05 g/t Au with a highest gold value of 1.24 g/t Au. Results of these rock samples are
shown in Table 1. Photographed examples of some of the rock samples in Table 1 are given below with brief
descriptions.

Preliminary geological observations show multi -phase dioritic stocks and intrusions with porphyry-style alteration
illustrating a classic porphyry zoning pattern from peripheral chlorite and epidote alteration with overprints of
retrograde argillic (clay alteration) and quartz + sericite to the core of a prograde weak potassic zone (including
potassium ( “K”) - feldspar alteration , quartz veining and secondary, hydrothermal magnetite alteration). The
alteration halo covers an area of approximately 1.5 kms by 1.5 kms and the potassic zone has dimensions of 800
metres (“m”) x 500 m. The porphyry s tocks are coincident with the circular features and Cu-Au-Mo geochemical
(soil) anomalies.
Copper mineralization including chalcopyrite + bornite + covellite and pyrite is associated with supergene malachite
and azurite coatings occurring within brecciated quartz veins. The presence of a large diatreme breccia (a common
feature for porphyry environments) in this area has been reported from historical work (Mt Suckling Explo ration
Report, Lindley et al 2012).
