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 / ACCESSWIRE / 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.

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.

Geochemical Sampling:

A wide-spaced, grid-based soil sampling survey was carried out using a hand auger drill at the Waki Prospect in June 2019 concurrent with the reconnaissance geological mapping program. The soil sampling program consisted of a grid with line spacing of 200 m and soil samples collected at 100 m intervals along these lines. Additional infill sampling to provide more detail between these lines may be carried out as follow-up exploration. Further soil sampling may be carried out southeast to cover areas with dioritic intrusive rocks and numerous mineralized copper rock floats in creeks. A total of 92 soil samples were collected during the soil sampling program. The geochemical results at Waki yielded an approximate footprint being 1000 m x 750 m with values of 140 to 212 ppm Cu, 7 to 17 ppb Au and 0.2-1.01 ppm Mo. The Cu and Au values are both coincident in the mapped diorite-basalt and limestone lithologies. These values are also coincident with favourable mapped intrusions strongly associated with porphyry-style hydrothermal alteration, supergene and hypogene copper mineralization and the presence of an airborne magnetic ("high") anomaly.

Figure 1 above illustrates the copper, gold and molybdenum values in soil samples collected from Waki Prospect and their coincidence with the airborne magnetic anomaly as depicted by the 25 m relative level ("RL") contour.

Geophysical Interpretation of Airborne Magnetic Survey

In November 2010, an airborne magnetic survey was carried out for Papuan Precious Metals ("PPM") by Fugro Airborne Surveys Pty Ltd ("Fugro"), with 200 m line spacing and 60 m flight height. A number of total magnetic intensity ("TMI") anomalies were revealed during this survey. One such anomaly is at the Waki Prospect, as illustrated by the stacked images in Figures 2 and 3. Waki creek is at an elevation of approximately 625 m RL while the top of Waki ridge is at approximately 825 m RL. The stacked images illustrate the Waki Prospect airborne magnetic anomaly at a range of elevations from 525 m RL (approximately 100 m below the Waki creek) to at least 600 m below the surface of Waki creek in the 25 m RL in Figure 3.

Figure 3: Stacked images of airborne magnetic survey (completed by Fugro for PPM) with orange contour illustrating Waki Prospect airborne magnetic anomaly at 25 m RL which is approximately 800 m below the top of the ridge at Waki Prospect. Note that PPM does not have any interest in the option agreement between the Company and Papuan Minerals Pty Ltd (the "Vendor") dated August 24, 2018 or the exploration licenses that make up the Keveri Project.

Figure 5: The airborne magnetic "high" anomaly at approximately 25m RL and the location of the Cu-Au and Mo soil anomalies and the location of the rock samples collected from outcrop and float. Note that the airborne magnetic image is at an RL of 25 m, indicating that its depth at this level is approximately 600 m below the surface at Waki creek. This demonstrates the large target potential at Waki Prospect.

Forward Exploration Program Planned for Waki Prospect

Future exploration at the Waki Prospect is designed to carry out the following exploration:

1. Continue detailed geologic mapping to identify areas of alteration and areas of mineralisation
2. In-fill soil sampling at 100 m line spacing and continue soil sampling to the southeast to cover anomalies that are not fully closed off
3. Additional collection of rock samples both from outcrop and float.
4. Petrological investigation of selective rock samples
5. Geophysical surveys; ground magnetic surveying to enhance the historic airborne magnetic data. Subject to the results of ground magnetic data and alteration mapping an induced polarization ("IP") survey may be warranted. The acquired data will aid in the compilation of 3-D geophysical models to assist with future drill hole targeting.
6. Identify suitable drill targets

Given the early stage of the Waki Prospect, these rock sample results represent only selected sampling and are therefore not representative of the entire Waki Prospect. Further exploration work is required included drilling before a representative grade of copper and gold can be determined for the Waki Prospect.
