International Goldfields resampling increases gold grades in Brazil

/in /by

THE DRILL SERGEANT: International Goldfields (ASX: IGS) has received assay results of one-metre re-sampling of reported mineralised zones in an additional eighteen RC holes for the recently completed RC drilling program at the Ana prospect located within the Latin gold project in Mato Grosso, Brazil.

“Assay results for the Ana drilling continue to demonstrate strong continuity of the PF quartz vein zone in RC holes AR019 through AR023, while results received on holes AR024 through AR036 on initial drill tests of targets at Ana prospect demonstrate the significant growth potential to define additional mineralisation at the Ana prospect area,” International Goldfields said in its ASX announcement.

The main discovery zone at Ana – recently named the PF Quartz Vein zone – returned increased gold grades from one-metre sampling located with favourable four-metre composite samples.

Better intercepts include:

–    11 metres at 3.03 grams per tonne gold from 22 metres, including 4 metres at 6.98 grams per tonne gold;

–    16m at 1.97g/t gold from 34m including 4m at 4.17g/t gold;

–    3m at 5.23g/t gold from 39m;

–    1m at 6.94g/t gold from 30m; and

–    2m at 3.6g/t gold from 45m and 2m at 1.4g/t gold from 54m.

“Further significant intercepts highlighted are located on additional structural targets and indicate the potential for multiple high grade mineralized structures with the 2.5km by 4km gold surface geochemistry zone that has limited drill testing,” the company said.

IGS has recently completed an additional eleven diamond drill holes at the Ana Prospect, with ten holes testing potential extensions to the PF Quartz Vein zone.

The first four holes of the diamond drilling targeted down-dip extensions to the PF Quartz Vein zone mineralisation to the south on the east-west trending mineralised zone.

These intersected additional intervals of high-grade gold mineralisation up-hole of the main target zone, with better intercepts including 1m at 36g/t gold and 2m at 14.3g/t gold.

The company considers these narrow high-grade intercepts indicate potential for a parallel mineralised structure located 80m north of the PF Quartz Vein zone and will require further work to assess mineralisation potential.

Drilling carried out on the main PF Quartz Vein zone lode indicated continuity of grade to over 120 metres depth for over 300m of strike with better intercepts including 3m at 3.51g/t gold and 10m at 3.3g/t gold.

Additional diamond drilling conducted in a subsequent six holes to test further strike extensions near surface along the PF Quartz Vein zone are pending analysis.

An eleventh and final diamond drill hole was drilled as follow-up work to test beneath disseminated sulphide mineralisation intersected in the final four RC holes at Ana that targeted better copper-molybdenum surface geochemistry anomalism.

Results of all diamond drilling and the final RC drill holes are pending assay analysis results.
