Challenger Exploration announced results from the ongoing rock saw channel sampling program at the Company's flagship Hualilan Gold project in San Juan province, Argentina. The sampling was undertaken using a rock saw to cut and recover a continuous channel measuring approximately 40cm x 40cm, with sample weight averaging 4.8 kg per metre. Samples were logged, and submitted for assay with QAQC samples (blanks and standards) using the same procedure as drill core. The channel sample is analogous to a drill core sample, and it is expected that the data can be incorporated into a resource estimation in the same way as drilling results. In light of the recent results from this program, notably the broader zones of mineralisation which appear to have been missed by the selective historical sampling, the program was extended to include channel sampling of all underground workings and exploration adits throughout the project including those located outside of the footprint of the known mineralisation. The current results are from underground channel sampling at Cerro Sur and include results from the Flor de Hualilan exploration drive which is located 550 metres south of CEL drill hole GNRC-052 (6m at 1.7 g/t gold, 4.4 g/t silver, 0.3% zinc), the southernmost drill hole at Hualilan to intersect mineralisation. This is the first time a systematic program of sampling has been conducted in many of the underground tunnels and the first time the Flor de Hualilan workings have been sampled. Sampling of the Flor de Hualilan Adit, which is believed to date from the 1800s, returned a number of high-grade intercepts with six of the eight channels returning high-grade mineralisation including 13.0m at 15.5 g/t AuEq, 9.2m at 5.1 g/t AuEq including 4.6m at 9.5 g/t AuEq, and 3.8m at 14.6 g/t AuEq. The mineralisation is open to the south, north, up-dip and down-dip and several channels ended in mineralisation. FDH-10-02 (down-dip) ended in 10.2 g/t AuEq, FDH-10-06 (up-dip) ended in 42 g/t AuEq, and the most southerly samples in the Flor de Hualilan adit recorded 12.1 g/t AuEq and 23.0 g/t AuEq. These high-grade results and broad zones of mineralisation in the channel sampling in the Flor de Hualilan Adit was not expected by the Company as the gold is not visible. In addition to these results, which extend the known mineralisation 550 metres south, historical mapping which was previously discounted, indicates sulphide mineralisation outcropping over approximately 500 metres strike south of the Flor de Hualilan Adit. Reconnaissance by the company has confirmed what appears to be weathered skarn mineralisation at surface well south of the Flor de Hualilan Adit. This extends the potential strike extent of the high grade skarn mineralisation by approximately 50% from 2.1 to 3.1 kilometres. The balance of the results are from channel sampling of the various adits and drives between Magnata and Sentazon at Cerro Sur. The sampling returned a number of high-grade results including 9.0m at 26.7 g/t AuEq, 10.5m at 14.0 g/t AuEq, and 5.2m at 10.7 g/t AuEq. This supports the likelihood of a continuous zone of high-grade mineralisation over at least 600 metres from Magnata in the north to Sentazon in the south. Additionally, the sampling returned a number of wide zones of mineralisation including 30.7m at 7.7 g/t AuEq and 52.0m at 3.4 g/t AuEq confirming the presence of broad zones of remnant lower grade mineralisation surrounding the higher-grade mineralisation.
