Sudbury, ON –March 11, 2021– Rockcliff Metals Corporation (“Rockcliff” or the “Company”) (CSE: RCLF) (FRANKFURT: RO0, WKN: A2H60G) is pleased to announce that an affiliate of Kinross Gold Corporation (“Kinross”) has earned a 70% interest in the Laguna/Lucky Jack/Puella Bay properties (“Laguna”) in Snow Lake, Manitoba.  Rockcliff retains a 30% participating interest in Laguna.  Pursuant to the July 2018 option agreement, Kinross has earned a 70% interest in Laguna by completing expenditures in excess of the required C$5,500,000 ahead of the third year anniversary of the six year option agreement.

“Having Kinross earn in so early on their option to the level of forming a Joint Venture on the Laguna Property confirms our belief of the high gold prospectivity of this land package. We look forward to seeing more encouraging results from this year’s program currently underway.” said Alistair Ross, President and CEO of Rockcliff.

Laguna is located in the Flin Flon-Snow Lake Greenstone Belt which is host to volcanogenic massive sulphide (copper-zinc) and primary gold mines and deposits. Laguna hosts the historic Rex-Laguna gold mine, Manitoba’s first and highest-grade former gold mine. Discovered in 1914, periodic gold mining up to 1940 produced over 60,000 ounces of gold with an average grade of 16.7 g/t. 

Since 2018, Kinross has completed 48 holes totaling approximately 16,470 metres.  Some of the higher-grade drill holes previously press released include:

• LG18-002: 15.00 m grading 0.54 g/t including 1.28 m grading 2.08 g/t and

• Winter Drill Program: Zona and North Kiski targets (13 holes in ~2,500 m)
• Mapping and Sampling Program at Lucky Jack, Laguna South and Puella Bay
