Highlighted samples include 137 g/t Au over 0.71 m and 54.20 g/t Au over 0.56 m

TORONTO, ON / ACCESSWIRE / April 26, 2022 / Graycliff Exploration Limited (the "Company" or "Graycliff") (CSE:GRAY)(OTCQB:GRYCF)(FSE:GE0) is pleased to announce field channel sampling results from its Phase 3 exploration program at Shakespeare Gold Project located on the prolific Canadian Shield near Sudbury, Ontario.

The channel sample results were located proximal to the historic Miller Shaft and the boundaries of the mineralized zone identified Phases 1 through 3 of our drilling.

The highlighted samples below include 137.00 g/t gold ("Au") over 0.71 metres ("m") (see Figure 1), 54.20 g/t Au over 0.56 m and 15.30 g/t Au over 0.49 m (see Table 1). Significant sample intervals are detailed below.

¹ Reported intervals are actual lengths of the channel samples. True width of the mineralization cannot be determined due to the early-stage nature of the current program.

President and CEO James Macintosh commented: "Graycliff has now completed over 7,000 metres of drilling at Shakespeare, spanning four phases, and recent channel sampling complimented our drilling efforts. We have identified the same style of mineralization at surface that we are also intersecting in drilling, which alludes to the consistency of the mineralized zone. We eagerly anticipate the receipt of the results of Holes J-25 through J-45 from the Phase 3 drilling campaign."

Mr. Macintosh added, "We now know that the mineralized zone, which we have expanded dramatically, goes from surface all the way down to over 250 metres below surface and remains open at depth and along strike. Given the success of the initial program, further surface channel sampling will be carried out as part of our summer 2022 exploration program. The goal will be to expand the footprint of the mineralization at surface to identify new zones for future drilling."
