Kairos’ Executive Chairman, Terry Topping, said: “We recently completed ~3,000m of RC drilling at Roe Hills and we’re pleased to report encouraging initial results from composite samples. The key area of focus is the Caliburn prospect, where we intersected wide zones of shallow gold mineralisation. These results have clearly demonstrated the potential to delineate potentially open pittable gold mineralisation at Caliburn.
“Given the proximity of Caliburn just 5km south of Silver Lake Resources’ French Kiss operations, adjacent to a haul road and in the heart of an active mining region, we can make a compelling strategic case to return to this area with further drilling in the near future.
“In the meantime, three-dimensional modelling work has commenced on existing drill data from the Caliburn, Lingering Kiss, Terra and Lady of the Lake prospects to underpin a maiden gold Mineral Resource Estimate. This will give us a good idea of the commercial potential of this project.

“In other areas, the broad sulphide zones intersected at Black Cat have returned interesting gold and zinc results, highlighting a potential VMS signature which requires further evaluation – particularly in light of a nearby soil anomaly. At Talc Lake, we intersected some narrow zones of nickel and copper sulphides with associated cobalt. We will evaluate next steps here after we receive the final 1m assay results.”
“In the meantime, our drilling program at the 873koz Mt York Gold Project in the Pilbara is making great progress with over 10,000m already completed. We look forward to providing updates on our work here and at the Kangan Project in the near future.”
Kairos Minerals Ltd (ASX: KAI; “Kairos” or “the Company”) is pleased to advise that all assay results from the composite samples have now been received from its recently completed Reverse Circulation (RC) drilling program at the 100%-owned Roe Hills Project , located east of Kalgoorlie in WA.
The drill program comprised 20 holes for a total of 2,992m testing high-priority gold and nickel targets at the Caliburn, Talc Lake and Black Cat prospects.
Caliburn Prospect
The Caliburn Prospect is located towards the southern end of the Roe Hills Project tenure, just north of Talc Lake and about 5km south-southeast of Silver Lake’s French Kiss gold deposit (Figure 1).
Kairos completed 10 holes for 1,149m at the Caliburn prospect. Drilling was carried out along four sections spaced 40m apart with drill holes on three of the sections returning mineralised intercepts (Figure 2).
Significant assay results include:

Black Cat Prospect
The Black Cat prospect lies at the northern end of Kairos’ 100%-owned Roe Hills Gold Project. The prospect is located in a structurally and geologically complex area, adjacent to the regionally significant Keith-Kilkenny Shear zone, host to Breaker Resources Ltd (ASX: BRB) Bombora Gold Project (23.21Mt at 1.3 g/t Au for 981koz) and Silver Lake Resources (ASX: SLR) Aldiss Project (8.715Mt at 2.1 g/t Au for 579koz).
During the 2020 field season, Kairos completed a soil geochemistry sampling program, and a strong and consistent gold anomaly was delineated over a strike length of 1,800m within Kairos’ tenure.
The Company completed six holes for 901m to test the gold-in-soil anomaly at the Black Cat Prospect. Hole RHRC120 returned the best gold intercept of 4m @ 1.63g/t Au from 48m (4m composite sample). The same drill hole returned a significant zinc anomaly, 20m @ 0.42% Zn from 96m from 4-metre composite samples. See table 1 for a complete list of results.
Kairos re-assessed the previous soil geochemistry results and delineated another soil anomaly 900m northwest of the drilling area with elevated copper, zinc, tungsten, molybdenum, thallium and bismuth. The Company is planning to conduct ground geophysics to study the potential for a VMS base metal system.
A plan view of the drill holes and the contours for the soil anomalies is shown in Figure 5. A cross-section of hole RHRC120 is provided in Figure 6.

Talc Lake Prospect
The Talc Lake Prospect is located toward the southern end of the Project tenure, adjacent to the west of the Keith-Kilkenny Lineament – Aldiss Fault Corridor, within an area of considerable structural complexity. A major NE-SW trending sinistral fault offsets the regional stratigraphy, while numerous subordinate N – NNW trending fault splays disrupt the prospective basement sequences at the local scale.
Kairos completed four holes for 942m at the Talc Lake Prospect. Hole RHRC115 returned the best nickel and copper sulphide intercept of 5m @ 0.55% Ni and 0.15% Cu from 96m including 1m @ 1.33% Ni and 0.45% Cu from 99m.
Results from this hole confirmed the extension of nickel mineralisation targeted at the up-plunge position of historical nickel intercepts, extending now over 80m and remaining open down-deep and toward the surface.
Multiple thin stacked komatiite flows were logged in hole RHRC115, including at the bottom of the hole. A down-hole electromagnetic survey was conducted with minor local anomalism detected in mid-channel centred at 95 to 105m downhole. No apparent off-hole anomalism was detected for modelling, leaving the down-deep zone as a further drill target to test the basal unit of the komatiite flows. The Company is assessing further drilling options to test the target, including diamond drilling.

The current drilling program was not able to test the interpreted eastern ultramafic unit due to depth constraints. However, a shallow zone enriched in cobalt and nickel was intersected in hole RHRC118.
Kairos is planning to collect the single-meter samples from the gold, zinc, nickel and cobalt intercepts in the three prospects drilled during the current program. As part of the target generation program, a field trip will be carried out once the Company receives the results from the current soil sampling program.
Maiden Gold Resource Estimation
The Company has commenced the 3D mineralisation modelling at the previously drilled Terra, Lingering Kiss, Lady of the Lake prospects, and will include the results from Caliburn prospect in the model once the assay results from the single-metre samples are returned. Kairos is aiming to calculate a maiden gold Mineral Resource with the data from the four prospects.
Ultrafine+ Soils Geochemistry Program
A total of 2,221 soil samples were collected and submitted to Labwest in Perth for Ultrafine+ analysis. Results are expected during the current quarter. The geochemical sampling program has covered the areas around

Caliburn, Lingering Kiss, Lady of the Lake prospects, including parts of the prospective corridor between Terra and Caliburn prospects. The program will assist the Company with further targets generation.
Airborne Geophysics – Woodcutters Project
Kairos’s contractor, Magspec Airborne Surveys, has commenced a magnetic and radiometric survey at the Woodcutters Project, located approximately 30km east of the Roe Hills Project (see Figure 6 for project location).
Past exploration conducted by Kairos at this project involved a small soil geochemical sampling program of 86 samples. The airborne survey is planned with 653 lines to be flown for 9,028km to cover the whole project area.
