SIENNA RESOURCES COMMENCES MULTI HOLE DRILL PROGRAM AT SLATTBERG COBALT-NICKEL-COPPER PROJECT IN SWEDEN

Sienna Resources Inc. has commenced drilling on its Slattberg cobalt-nickel-copper project in Sweden. This maiden drill program will consist of five to seven prioritized drill holes of 125 to 200 metres in length.

The first holes will target a zone of massive sulphide mineralization intercepted in historic drilling (1970 era) near the Helenegruvan mine. The first hole will target a shallow zone of mineralization intersected in previous drill holes, but will be assayed for a wider range of elements than the historic drill holes, including gold and platinum group elements. Other holes will test downdip extensions of the mineralization that were not tested by the shallow historic drill holes.

The second group of drill targets will focus on a strong magnetic anomaly identified by 2018 ground magnetic surveys in the vicinity of the Myrgruvans mine. This robust magnetic anomaly is positioned to the east of the mine workings, and has not been tested by historic drilling.

Other drill holes will target the western end of the trend of mine workings, where the most voluminous mining took place, and mineralization remains open at depth.

Jason Gigliotti, president of Sienna, stated: "We are very pleased to be commencing our first major drill program in many years. Our shareholders have been patient and we feel this project has great potential and we are looking forward to what the next few months will return. This phase of drilling will provide a strong start to build on the historic data. We are at the early stages of this project and look forward to bringing this project forward with modern approaches and views at a time when the battery metals sector is gaining significant traction globally."

Earlier this month, Sienna significantly increased its acreage on its Slattberg cobalt-nickel-copper project. The Slattberg cobalt-nickel-copper project now consists of three exploration licences covering 12,733 acres and at least 16 historic mines, with one being the historic Martanberg copper mine, which was operated in the late 1700s and early 1800s. The Martanberg field is known for its copper-rich skarn-style mineralization. The underground workings extended to depths of 80 to 100 metres, and little to no modern exploration has been conducted in the area. The company plans to bring modern techniques and views to this added acreage.

On Jan. 30, 2018, the company announced that initial results have been received from the continuing magnetic survey work on the Slattberg cobalt-nickel-copper project in Sweden. High-resolution magnetic surveys in the area of historic nickel-copper-cobalt mines have defined multiple strong magnetic responses along the trends of mineralization. These areas of strong magnetic response are interpreted to represent steeply plunging bodies of massive sulphide mineralization that is rich in pyrrhotite. The magnetic data appear to confirm additional continuity of drill-defined zones of mineralization known from the historic drilling. Along with the historic drill data, these new magnetic data are being used to define multiple high-priority drill targets for the upcoming drill program.

Slattberg's massive sulphide mineralization is known to be strongly magnetic, owing to its high concentrations of pyrrhotite, a magnetic ferrous sulphide mineral associated with the Co-Ni-Cu (cobalt-nickel-copper) mineralization. The new magnetic data are being used to potentially generate additional high-priority drill targets on the project.

About Sienna Resources Inc.

The Slattberg cobalt-nickel-copper project now consists of three adjacent exploration permits comprising approximately 12,733 contiguous acres.

Slattberg is located 25 kilometres northwest of Falun, Sweden. Slattberg is a historic mining camp hosting cobalt-nickel-copper-rich massive sulphide mineralization that occurs within a two-kilometre belt of historic nickel-copper mines. The project contains drill-defined massive sulphide mineralization that extends to about 100 metres in depth, and remains open for expansion at depth and along strike.
