Great Northern Minerals : High grades from reconnaissance sampling at Douglas Creek

About this update from Great Northern Minerals Limited

For personal use only ASX Announcement 3 1 May 2022 High Gold-Silver-Copper grades returned from reconnaissance sampling at Douglas Creek prospect Highlights: Reconnaissance sampling program at Douglas Creek discovers outcropping high-gradegold-silver-copper mineralisation 15 samples taken over an area 900 by 170m - majority of samples returned strong gold, silver and copper assays - up to 2.0 g/t Au, 88 g/t Ag and 11.0% Cu GNM targeted an area of anomalous bulk cyanide leach sampling dating from 1988 - with no known historical workings in area Great Northern Minerals Limited ( ASX: GNM ) (" GNM " or the " Company ") is pleased to announce the results of a reconnaissance sampling program at the Douglas Creek prospect, located on EPM 27522, part of GNM's Golden Ant Project in North Queensland. Samples were taken from outcrop and float in an area with no known historical workings. The sampling program was designed to follow up a historic bulk cyanide leach gold (BCL) anomaly, dating from 1988, where sampling returned assays of up to 4 ppb (parts per billion) Au. Fifteen samples were taken from outcrop and surface float from an area approximately 900 by 170m. The majority of samples returned strongly anomalous gold, silver and copper grades of up to 2.0 g/t Au, 88 g/t Ag and 11.0% Cu. Further soil sampling and rock chip sampling will be carried out in June to follow up this exciting new discovery.

The sampling program was designed to follow up highly anomalous BCL Au sampling results from 1988. The majority of samples returned highly anomalous gold, silver and copper grades from an area of no known historical workings over an area of approximately 900 by 170m We intend to follow up these exciting results with a detailed soil sampling program and further rock chip sampling planned to take place in June".

Fifteen samples were taken over an area of approximately 900 by 170m (refer to Table 1 for sample descriptions and assay results). The reconnaissance program was designed to follow up a bulk cyanide leach (BCL) anomaly discovered in 1989 and never followed up. The BCL anomaly is located in an area with no known historic workings. The samples returned highly anomalous gold, silver and copper grades of up to 2.0 g/t Au, 84 g/t Ag and 11.0% Cu from mesothermal style mineralisation. GNM plan to complete a systematic soil sampling grid over the area combined with a more extensive rock chip sampling program to better understand the extent of the mineralisation. This program is scheduled to take place in June.

The Company's Golden Ant Project is located in Far North Queensland and includes the Amanda Bell and Big Rush Goldfields. Total gold production from the Amanda Bell Goldfield was approximately 95,000 oz Au (57,000 oz from Camel Creek and 14,000 oz from Camel Creek satellite deposits plus 18,000 oz from Golden Cup and 6,000 oz from Golden Cup satellite deposits). Total gold production from the Big Rush Goldfield was 60,000 oz Au. Three heap leach gold mines were operated (Camel Creek, Golden Cup and Big Rush). Mining activities commenced in 1989 and ceased in 1998 with the depletion of oxide gold mineralisation. Great Northern Minerals aims to develop a new gold camp in North Queensland based on the Golden Ant Project.
