RosCan Defines Numerous Strong Gold Anomalies at Its 100%-owned Kandiole Gold Project in West Mali

Toronto, September 21, 2018 - RosCan Minerals Corp. (TSXV: ROS) ("RosCan" or the "Company"), is pleased to announce that it has identified numerous high quality gold geochemical anomalies at its 100%-owned Kandiole Project in west Mali. Immediate drilling is warranted and planned for November 2018.

During June and July of this year, RosCan conducted a detailed geochemical sampling program, consisting of soils and termite samples, on the Mankouke and Moussala Nord permits. This program was completed just prior to the commencement of 2018 rainy season and was identified from the reconnaissance prospecting program completed during the dry season of this year. These two areas represent only 20 sq. km of the contiguous 271 sq. km Kandiole Project land package.

A total of 4,916 samples were collected, including 2,806 soil samples and 2,110 termite mound samples. Samples were collected on lines 100 to 200 metres apart with sample stations every 50 metres. There are many anomalous values and these sample values are outlined on the attached maps. Most of the anomalous samples align along northerly trending corridors up to 350 metres wide with individual anomaly groups extending for a minimum of 600 metres along strike.

As can be seen from the attached maps a small portion of the Kandiole Project area was covered with detailed sampling. Map No. 1 shows the Kandiole Project land package with results of work to date and the areas of detailed sampling. Maps No. 2 and 3 show the results of the sample analyses and gold anomalies of the Mankouke and Moussala Nord areas respectively. These major anomalies will first be checked in the field, prioritized and subjected to a first pass drill testing, expected to be conducted in November 2018.

COMMENTARY
Greg Isenor, President and CEO of RosCan stated: "We were quite surprised and rewarded by the amount and strength of these new Au-in-soil and termite mound anomalies that were identified in an area of existing gold mines and along same structures, that management believes, host the nearby, recent discoveries by Oklo Resources and Komet Resources. Our plans are to build on these exciting results, start drill testing the targets and carry out the easy, next steps of collecting more soil and termite samples in this overlooked, highly prospective area."

QUALIFIED PERSON AND SAMPLE PROTOCOL
The technical content in this news release has been reviewed and approved by Gregory P. Isenor, P. Geo, a Qualified Person as defined by NI 43-101.

For quality control, duplicated samples were systematically collected in the field, and blank samples were inserted in the sample batches sent to the laboratory. A total of 91 blank samples and 98 duplicates were included in the sample batches sent to the lab. Before their transportation, the samples were stored in a RosCan secured location in the field. Batches of samples were transported by truck, driven by RosCan contractors, up to the sample preparation installations of Bureau Veritas laboratory at Bamako; prepared samples were then shipped by Bureau Veritas to their treatment installations at Abidjan, Ivory Coast. During the assay process, the laboratory applied its own quality controls with blanks, duplicates and standard samples. The assay method was atomic absorption (AA) with pre-concentration by fire assay (FA); the detection limit of the method is of 5 ppb.
