Castle Peak Mining Ltd. Provides Third News Release on Corporate Developments Since its TSX Venture Exchange Trading Halt 90 Days Ago

Vancouver, May 17, 2019 - Castle Peak Mining Ltd. (TSXV: CAP) ("Castle Peak" or the "Company") hereby provides a third news release on corporate developments since its TSX Venture Exchange trading halt 90 days ago.

The Company is pleased to announce that it has concluded the NI 43-101 technical report ("technical report") on the Kunsu PL property, which has been authored by Prosper Mackenzie Nude, PhD., MAIG, a member of the Australian Institute of Geoscientists with registration number 7381. Following the approval of the technical report by the TSX Venture Exchange the Company has filed the technical report with signature date of 3^rd May, 2019 on Sedar.

Finally the Company is pleased to announce the latest field progress update on the ongoing follow-up exploration work. This work commenced on the 22^nd February, 2019 and has covered the 5.8 km Induced Polarization (IP) geophysical survey at the North Grid zone, followed by 882 meters of trenches excavated on the geophysical defined targets. This involved 737 samples, comprising 668 trench samples and 69 Quality Control-Quality Assurance samples, submitted to the ALS laboratories in Kumasi, Ghana for Au analysis by Fire Assay and AAS finish.

The Company is pleased to report that the current trench results returned significant Au grade (> 100 ppb Au) intersections hosted within quartz vein lodes. Notable are trenches GKUTR004, GKUTR005 and GKUTR006 which are on strike length of 300m within the West-North Grid anomaly zone, and trenches GKUTR009 and GKUTR010 on 100m strike length within the East-North Grid anomaly zone; mineralization is open ended west of GKUTR004. A 300m lateritic zone, inferred at this stage to be masking mineralization and Au expressions, separates the West-North Grid and the East-North Grid anomaly zones. A summary of results from trench samples of significance Au grades (>0.1g/t Au) is presented in Table 1.

Table 1: Results from the trench intersections with Au grades >0.1g/t

These results from the trench samples provide compelling evidence of significant Au mineralization within the North Grid zone of the Kunsu property; the mineralized zone is traceable 1km on strike, separated by 300m of lateritic zone which is being investigated further.

The Company is in progress to preparing for a drilling exercise to be based on a combination of the gold in trench sample anomalies and the geophysical IP survey result.

ON THE KUNSU PROPERTY

The Kunsu PL is located approximately 35 Km Northwest of Kumasi and 240 Km Northwest of Accra; the property is centred approximately on Latitude 6°48'00'' North and Longitude 1° 56.00'' West (WGS84 Zone 30N). The property which is situated in close proximity to the Sefwi gold belt is strategically placed on the Asankragwa-Manso Nkwanta gold belt. The Kunsu concession is about 27 Km north of Asanko Gold's mine, and even closer to the Asanko Esaase gold prospect, all of which are inferred to be underlain by similar geology regionally as Kunsu.
