Graycliff Exploration Completes Phase Three Drilling at Shakespeare Project, Ontario

High-grade gold mineralized zone open in all directions

Graycliff Exploration Limited (the "Company" or "Graycliff") (CSE:GRAY)(OTCQB:GRYCF)(FSE:GE0) is pleased to announce that the Company has completed Phase Three drilling (see press release dated June 3, 2021) at its Shakespeare Gold Project located on the prolific Canadian Shield near Sudbury, Ontario. The program successfully expanded the extent of alteration, quartz veining and gold mineralization proximal to the historic Miller Shaft

To date, Graycliff has drilled approximately 7,000 metres in the first three phases at Shakespeare, reporting assay results (See Table 1) on 24 out of 45 completed holes and significantly expanding the existing mineralized zone surrounding the Miller Shaft by approximately 150 m at depth and 120 m along strike. The mineralized zone, which strikes NE-SW, remains open to expansion in all directions (see below Figure 1). The original green zone was from two aligned holes in green.

President and CEO James Macintosh stated: "Our original exploration thesis was built around the theory that the high-grade gold zone started from surface and was open at depth, and our work to date confirms that theory. Throughout all three phases of drilling we have been discovering significant mineralized intervals with high grades, often where visible gold is present in the drill core. We still have twenty one holes left to report and we are already gearing up for Phase Four drilling which will look to expand the zone along strike and will also include exploratory holes in other areas of the property where there are geological similarities to the surface results that we encountered during the first three phases of drilling."

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.
