Surprise Creek Project Historical Data Review Highlights High-Grade Uranium and Copper Targets Including Drilling Results of 2.1m @ 4.37% U3O8
URANIUM HIGHLIGHTS
- Historical drilling on the Surprise Creek Fault target highlighted by 2.1m @ 4.37% U3O8 from 57m (VT20) including 0.9m @ 7.5% U3O8
- Other significant historical drilling results at Surprise Creek Fault target include 1.5m @ 0.1% U3O8 (VT13), 0.43m @ 0.49% U3O8 (VT05) and 0.15m @ 0.83% U3O8 (VT02)
- Surprise Creek Fault target comprises a uranium geochemical anomaly (>25ppm U) in soils over 500m in strike length and including rock chips up to 6.37% U3O8, associated with a north-northwest striking fault system
- Uranium soil geochemical anomaly was partially drill tested and remains open in several directions
- The Exploration Model is a structurally controlled vein type uranium deposit, a sub-type of the basement- hosted unconformity-related uranium deposits
- Reconnaissance field work to commence in mid-July with geological mapping and rock chip sampling to validate the current targets and improve geological understanding of the exploration model.

COPPER HIGHLIGHTS
- Data review also highlights several copper targets in the southwest of the project area with soil and rock chip anomalies (>150ppm Cu) over a strike length of 1.5km and open to the north and south.
- Copper target areas include several rock chip samples >0.25% Cu, up to 5.9% Cu and soil samples up to 3,300ppm Cu.
- Valor’s landholding increased in the area following historical data review, with an additional 11 km2 pegged to the southwest of the copper anomalies.
- No modern exploration for uranium or copper in the project area for over 20 years.

Executive Chairman George Bauk commented “The historical data review has highlighted some exciting uranium and copper targets with the high-grade uranium drill results of 2.1m @ 4.37% U3O8 at Surprise Creek Fault being most noteworthy. The historical results and lack of modern exploration for over 20 years suggests there is great potential in this area.”
“Based on the historical data review, the Company increased its land position at the Project to the southwest by pegging a further 11km2. Given the copper mineralisation trend at the southwest part of the property, we thought it was only logical to peg the open ground.”
“We are continuing to work through the historical exploration data from our eight projects in the Athabasca Basin and will release further results of these reviews in the coming months. The exploration team will commence on-ground work at the Cluff Lake and Surprise Creek Projects in July and results of the recently completed airborne gravity surveys at the Cluff Lake, Hook Lake and Hidden Bay Projects will be finalised during the current quarter."
Historical data review targets
The following targets are based on a thorough review of historical exploration data which has been integrated with a detailed geological interpretation of all publicly available geophysical data completed by Valor’s consultant geophysics team, Terra Resources. The historical exploration data is from the 1950s through to the late 1970s. Between the 1980s and the present day, little uranium or copper exploration has been carried out in this area. Details of relevant drill holes and surface sampling information that have been used in determining some of these targets, have been included in Appendices 1, 2 and 3. All diamond drill holes have been reported and surface samples reported have been filtered based on: Soil samples > 2ppm U, rock chip(boulder) and unknown sample types > 5ppm U. Due to the historical nature of some of this data, some aspects of the sampling and drilling cannot be verified and therefore some caution must be applied. The Company intends to carry out on-ground work to verify aspects of the historical data before advancing targets to the next stage.
Surprise Creek Fault
The Surprise Creek Fault target is an area where uranium exploration occurred in the late 1960s. The most significant exploration was conducted by Van-Tor Resources who completed 27 diamond holes in 1968 to test an area of uranium mineralisation at surface. Prior to that, in 1955, Independence Mining drilled 14 shallow (mostly 25-50m and up to 85m deep) diamond drillholes in the area following prospecting and trenching, which located uranium mineralisation at surface.

- Cores from completed holes 14, 15 and 16 are currently being assayed at the ALS laboratory in Brisbane with results expected progressively
The Company is pleased to receive further assays from Hole 02 and Hole 04 at its 100% owned Halls Peak project in New South Wales. Results continue to demonstrate the scale potential of the Halls Peak system, particularly at depth. Results continue to provide strong support for an expanded drill program.
Critical Resources Managing Director Alex Biggs said:
“We’re continuing to see some fantastic intersections at Gibsons that are demonstrating the potential of the Halls Peak system. Drilling is ongoing across multiple targets as we look to start to further define the potential scale at Halls Peak. The asset is shaping up as potentially transformational for the Company and we look forward to updating the market with more exciting results”.
