Graycliff Exploration Extends Zone of Gold Mineralization by 50 metres at Depth with Additional High-Grade Intervals at Shakespeare, Ontario

Graycliff Exploration Limited (the "Company" or "Graycliff") (CSE:GRAY)(OTCQB:GRYCF)(FSE:GE0) is pleased to announce assay results from drilling on its Shakespeare Gold Project located on the prolific Canadian Shield near Sudbury, Ontario. The results are the initial assays from the 2021 portion of the Phase Three program (see press release dated June 3, 2021) that is focused on expanding on the extent of gold mineralization proximal to the historic Miller Shaft where initial gold mining took place more than 100 years ago

Drill Hole J-22-21 intersected two mineralized intervals of over 46 g/t gold ("Au") over 2.70 metres ("m") and 4.80 metres, respectively. The wider and deeper intersection included 13.20 g/t Au over 0.80 m and 415.00 g/t over 0.50 metres. Significant intervals for holes J-22-21 to J-24-21 are detailed below:

¹ Reported intervals are down-hole lengths and not true thicknesses. True width of the mineralization cannot be determined due to the early-stage nature of the current program.

² Length-weighted average grades are calculated using un-capped gold assay data.

President and CEO James Macintosh stated: "Phase Three drill hole locations were selected utilizing the results from the first two phases of drilling. We continued to focus on the gold mineralized zones proximal to the Miller Shaft, but also drill tested the boundaries of the zone. Drill holes J-22-21 and J-23-21 both intersected strong alteration and veining and samples from drill hole J-22-21 returned great results with two sections of high-grade gold mineralization at depth, further extending the mineralized zone by approximately 50 m. The zone remains open at depth and along strike."
