Sudbury, ON – January 20, 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 commenced a Winter 2021 drill program at Rockcliff’s Laguna Gold Property (“Laguna”) and Lucky Jack Gold Property (“Lucky Jack”) in Snow Lake, Manitoba. The planned 2,600 m drill program will focus on areas below high grade surface gold mineralization and northeast trending structures identified in previous work programs. Pursuant to the July 2018 option agreement, Kinross may earn up to a 70% interest in Laguna and the Lucky Jack by spending $5,500,000 over the 6-year term of the option agreement.
The Laguna and Lucky Jack are 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. Laguna includes 28 contiguous mining claims totalling 3,501 hectares.
2020 drill hole gold intercept highlights include:
Two separate drill programs were completed at Laguna totaling 10,714.31 m in 25 holes. Phase 1 totaled 5,242.6 m in 13 holes (LG20-001-LG20-013) and partial results were press released on August 28, 2020. Phase 2 totaled 5,471.71 m in 12 holes (LG20-014-LG20-025). A comprehensive assay table with significant results from both phases of drilling are highlighted below. Drill intersections are not true thicknesses as additional drilling will need to be completed to determine true thicknesses of the mineralization. Drill holes LG20-003, 006, 007, 011, 014, 015, 017, 018, 025 failed to intersect significant gold mineralization.

Drilling and mapping conducted at Laguna in 2020 was successful in expanding existing mineralized zones, discovering new targets and improving the understanding of the property geology and controls on gold mineralization (Figures 1 and 2). Typical accessory mineralization associated with gold mineralization at Laguna is arsenopyrite which is predominantly associated with strongly sericitized and silicified rhyolite and in quartz veins. The arsenopyrite is predominantly disseminated within the sericitized zones and generally follows along hairline fractures and margins of quartz veins.

Drill Program Underway-Winter 2021
Approximately 14 holes totaling approximately 2,600 m are planned at Laguna and Lucky Jack.
Drilling has commenced at the Lucky Jack (immediately south of Laguna) where 7 holes are planned in the vicinity of surface gold mineralization in quartz veining along strike of the historical Zona Shaft and at the historical Lucky Jack showing. The highest grade assay from Zona was 32.9 g/t gold and the best result from the Lucky Jack area was 4.4 g/t gold. Granodiorite is the host rock to the veining in both areas.
Additional drill testing will be centered on several northeast trending structures recently identified in magnetometer and Lidar surveys at Laguna.
Quality Control and Quality Assurance
Drill core is logged and sampled in a secure core storage facility located in Snow Lake, Manitoba. Core samples from the program are cut in half, using a diamond cutting saw and are sent to ALS Geochemistry in Thunder Bay, Ontario. ALS North America is accredited under ISO/IEC 17025:2017. All samples are analysed for gold using standard Fire Assay-AA techniques. Samples returning over 3.0g/t gold are analysed utilizing standard Fire Assay-Gravimetric methods. Certified gold reference standards and blanks are routinely inserted into the sample stream as part of the quality control/quality assurance program.
Information for the 2020 drill program is tabled below.
