PREAMBLE

Perseus is pleased to provide an update on its recent exploration activities at its Bagoé and Yaouré properties, both located in Côte d’Ivoire. The results demonstrate the potential for the Company to organically grow its gold inventory through further drilling success.

Yaouré is Perseus’s third gold mine, commencing production in December 2020. Recent exploration has focused on the drilling of satellite prospects within five kilometres of the Yaouré mill with the potential to deliver shallow oxide ore during the early stages of the project. Progress has also been made with the definition of drill targets from the 3D seismic survey completed in 2020, recently supplemented by the completion of an airborne gravity (FTGG) survey.

The Bagoé exploration licence, 60km south of Perseus’s Sissingué Gold Mine, was acquired when Exore Resources Limited was acquired in September 2020 (ASX announcement September 26, 2020). Perseus’s pre-acquisition evaluation of Exore’s exploration work at Bagoé indicated potential for the economic exploitation of the Antoinette, Juliette and Véronique gold deposits by open pit mining and either processing in-situ or transporting ore to Sissingué for processing. Recent exploration drilling has focused on converting the previously defined Inferred Resources to Measured and Indicated Resources to support a DFS to confirm the technical and financial viability of the two development concepts.

YAOURÉ EXPLORATION DRILLING – GOVISOU AND ANGOVIA 2 PROSPECTS

Perseus has focused recent exploration activities at the Yaouré permits on the Angovia 2 and Govisou prospects, both within 5km of the Yaouré mill.

Particularly encouraging results have been returned from the Govisou prospect, 3km southwest of the Yaouré mill site, where 5,642 metres were drilled in 61 Reverse Circulation (“RC”) holes (with an additional 1,127 metres drilled in 14 holes during the December 2020 quarter). Mineralisation at Govisou occurs in pervasively altered and pyritized basaltic-andesitic volcanics intruded by a dioritic stock, with no clearly identifiable structural controls. Better intercepts from this drilling programme are included in


Table 1


below.

The geometry of the Govisou mineralisation remains uncertain at this stage, but current indications suggest a ‘pencil’-shaped plunging structure that remains open at depth. Further drilling, including oriented diamond core holes, is planned to elucidate the structural and lithological controls on mineralisation at Govisou.

At Angovia 2, located 3 kilometres southeast of the Yaouré mill, results were received for Resource definition drilling completed in the December 2020 quarter aimed at defining shallow ore beneath the planned oxide pit. The results from this campaign suggest potential exists for a deepening of this pit beyond the currently planned depth. Better intercepts from this program are included in


Table 1


below.

Ongoing exploration programmes at Yaouré will focus on:

• Follow up drilling at Govisou to elucidate the lithostructural controls on the mineralisation and to follow potential down plunge extensions to the high-grade pod defined in the latest drilling.
  
• The commencement of drill testing of targets generated from the 3D seismic survey conducted in early 2020, with an initial focus on near-surface targets.

BAGOÉ EXPLORATION PERMIT

Resource definition drilling was undertaken at the Antoinette, Véronique and Juliette prospects on the Bagoé permit. A total of 18,665 metres was drilled in 52 Air Core (“AC”), 252 RC and 6 diamond drilling (“DD”) holes, plus nine geotechnical and exploratory water bores. Almost all results have now been received for this drilling, generally confirming the tenor and width of previous drilling and suggesting possible extensions.

At Véronique, drilling defined strong mineralisation over a core zone of approximately 440 metres over widths of 3 to 9 metres. Better intercepts are shown in


Table 2


.

At Juliette, drilling confirmed strong mineralisation over a strike length of 250 metres with widths ranging from 4 to 22 metres. The mineralisation remains open to the southwest and at depth. Better intercepts from the Juliette drilling are included in the second column of


Table 2


.

Drilling at Antoinette Central was also successful in confirming strong mineralisation over a strike length of 875 metres with average widths of 5 to 44 metres. The mineralisation appears to remain open to both the northeast and southwest and at depth. Better intercepts from the Antoinette drilling are included in the last column of


Table 2


.

Exploration will now focus on investigation of other prospective opportunities identified on the Bagoé tenement, including:

• Strike and dip extensions to known deposits identified from the recent resource drilling.
  
• The Antoinette-Juliette ‘gap’ to follow up previous encouraging intercepts in AC and RC drilling beneath transported cover.
  
• Drilling to follow up encouraging drill intercepts between Antoinette and Antoinette South.
  
• Drilling to follow up encouraging intercepts on potential repetitions of the Véronique deposit and at regional prospects such as Odette and Brigette.
  
• Augering at early-stage regional prospects such as Ludivine.
