Exploration Results Validate Copper Potential at Kitumba 27715 Project -Target B1

Jane Morgan Management

HIGHLIGHTS:

• Detailed geological field mapping and sampling program at Target B1 confirms consistent copper mineralisation across 40m strike.
  
  

• Best pit-grab sample returned 0.80% Cu and averaged 0.34% Cu over a 10m wide quartzite unit.
  
  

• Best trench intersection returned 0.19% Cu over 7m demonstrates mineralisation and remains open laterally and along strike.
  
  

• Follow up program to include 600m trenching program spaced ~60m apart and a 30 hectare Induced Polarisation survey (“I.P.”) over the target.
  
  

Patriot Resources Limited (“Patriot”, “PAT” or the “Company”), is pleased to announce positive assays from the recent channel sampling program on Target B1 within Kitumba 27715 project, Zambia.

A detailed channel sampling program was recently completed across two historical trenches (OTR01 and OTR02) complemented by grab sampling from two artisanal pits (Pit 1 and Pit 2) located between the trenches. This work followed up on the initial mapping and pXRF program conducted at the start of the year, which first identified copper mineralisation within the pits.

Results from trench OTR02 averaged 0.19% Cu over 7m (0m-7m), while rock grab samples from the two pits returned an average grade of 0.34% Cu over a 10m wide carbonaceous quartzite horizon. Surface sampling has now defined a 40m NE-SW copper-bearing strike, with strong potential for both lateral and along strike extensions based on field mapping observations. To advance the target, the Company is now planning a detailed follow up trenching program and I.P. survey over the target to identify subsurface sulphide zones.

PROJECT BACKGROUND
The Kitumba 27715 Project is located 13km North-West of Mumbwa town, and approximately 150km North-West of Lusaka, Zambia. The large-scale exploration licence (tenement number 27715-HQ-LEL), covers ~25,511 hectares (255km²). Target B1 lies ~15km South-East of the Sinomine Kitumba deposit. The licence is prospectively located within the Kitumba Iron Oxide Copper Gold formation (“IOCG”) corridor, where the Hook Granitoid Suite intrudes a sequence of carbonates and calc-arenites interlayered with shales and siltstones of the Katanga Supergroup.

WORK DONE
The two historical trenches were cleaned using picks and shovels prior to geological mapping and sampling. Each trench measured on average ~59m long, 1m wide, 1m deep and running West-East, oblique to the main structure. The host rock sequences comprises of sandstone with intercalations of shale and quartzite. The quartzite is limonitic, carbonaceous, brecciated and shows visible chalcopyrite and malachite staining. The quartzite trends NE-SW and is steeply dipping.

A total of 144 rock-chip samples, including QAQC samples, were collected during the program and samples were sent to a certified lab for copper analysis. Assay results confirmed positive copper mineralisation from both trench OTR02 and the artisanal pits.

RESULTS
The results confirm consistent copper mineralisation, with trench OTR02 averaging 0.19% Cu over 7m (0m-7m), and grab samples from the two artisanal pits averaged 0.34% Cu over a 10m wide carbonaceous quartzite unit.

Surface sampling has now defined a 40m mineralised strike from the channel assays with possibility of extension based on field mapping observations. Importantly, trench OTR02 was terminated prematurely within the copper bearing quartzite, suggesting the mineralisation continues laterally beyond the exposed section. To advance the Project, the Company will conduct a follow up trenching program together with I.P. survey. A total of 600m of trenching has been planned for Phase 1 with trenches spaced approximately 60m apart. A 30 hectare I.P. survey block has been proposed over the target to effectively detect disseminated copper sulphides.

NEXT STEPS

• Conduct a follow up trenching program targeting lateral and strike extensions
  
  

• I.P. survey to map subsurface sulphidic zones
