Golden Birch Outlines Recent Discovery at Keveri Project, called “Waki”
Waki Located 1 km East of Omu
Waki Exhibits Characteristics of Tier 1 Porphyry Cu-Au Deposit
Waki Discovery Yields Anomalous Cu and Au in Multiple Outcrops
Assay Values from Separate Outcrops Yield Up to 4.9% Cu & 15.5 g/t Au
Exploration at Waki at an Early Stage and Results Not Representative
Timmins, Ontario (March 25, 2020) - Golden Birch Resources Inc. (CSE:GBRX) (“Golden Birch” or the “Company”)
is pleased to provide detailed information on its recently discovered Waki Prospect ( called “Waki”) located east of
the Omu Prospect.
Highlights:
• Initial discovery of the Waki Prospect made by Golden Birch geologists in May 2019
• Reconnaissance exploration by Golden Birch geologists yields visual copper mineralisation in float and
outcrop 1 kilometre (“km”) east of Omu Prospect
• Exploration results yield anomalous copper and gold, with best results to date from separate outcrops being
0.34% Cu and 15.5 g/t Au and 4.9% Cu and 0.05 g/t Au
• Assay values from selective rock float samples in drainages associated with Waki Prospect area yields values
as high as 6.8% Cu and 15.45 g/t Au from separate samples
• Exploration at Waki is at an early stage and assay values from in situ outcrop and float samples are selective
in nature and therefore not representative of the overall target at Waki. Further work is required before a
representative grade for copper and gold can be determined for the Waki Prospect
• Waki Prospect has yielded anomalous copper and gold mineralisation in multiple in situ outcrops and
selective float samples over an area of approximately 1.0 km north-south by 0.8 to 1.0 km east-west
• Wide spaced, reconnaissance soil survey yields anomalous and coincident copper (Cu), gold (Au) and
molybdenum (Mo) values over a 400 metre (“m”) to 600 m north-south by 800 m to 1000 m east-west area
• The Cu-Au-Mo anomalies are coincident with an airborne magnetic “high” anomaly
Alan Martin, President of Golden Birch states, “I am excited that our exploration team discovered a new prospect in
our 2019 exploration program which has the potential to deliver new drill targets at the Keveri Project. When we
signed the option agreement with the vendor in 2018, there was no geological information on the Waki Prospect. A
common feature for some porphyry copper deposits is that they occur in clusters. It is exciting for the Keveri Project
to now host two prospects being Omu and Waki with characteristics of Tier-1 porphyry copper – gold deposits”.
Exploration Completed at Waki
Geological Mapping:
In April 2019, an altered and mineralised rock float sample was discovered by a Golden Birch geologist east of Waki
creek. The rock float yielded a value of 3.88% Cu, 0.049 g/t Au and 4.7 g/t Ag (Photo 1). Subsequent to this initial
discovery, reconnaissance geological prospecting and mapping was carried out east of Waki creek to trace the source
of the mineralized rock float. This initial prospecting work revealed copper mineralization, both in rock floats and
outcrops, hosted mostly in intrusive rocks. As a result, a program of detailed geological mapping was initiated at
Waki Prospect.
The Waki Prospect is located approximately 1000 m east of the Omu Prospect (Figure 1). An initial 1:5000 scale
geologic mapping program was completed at the Waki Prospect which generated geological data and interpretive
maps. This work was followed up by a more detailed 1:1000 geologic mapping program from late April to June 2019.
Additional 1:1000 scale geologic mapping is warranted at the Waki Prospect.

prospect by Golden Birch geologists is located approximately 1000 m east of the flagship Omu Prospect.
A total of 71 rock samples were obtained from the Waki Prospect for analytical and petrological investigations during
the initial geologic mapping campaign. Geologic mapping to date at the Waki Prospect has confirmed strongly
fractured porphyry-style intrusive rocks, hydrothermal alteration as characterised by porphyry deposits being
chlorite, epidote and secondary hydrothermal magnetite with phyllic (quartz+sericite+pyrite) overprint. Some of the
samples from creeks and outcrops display visible supergene-hypogene copper mineralization (chalcopyrite and
malachite).
Results of the geological mapping are illustrated in Figure 2. Below are photos of select rock samples from in situ
outcrop and float samples collected from the Waki Prospect by the Company. The location of these samples are
illustrated in Appendix 1.
