Mt Clermont Gold Project
Location and Tenure
The Clermont Project, EPM 14116 (Figure 10) is located in the southern part of the Drummond Basin in Central Queensland, approximately 60 km by road north-west of the town at Emerald and 330 km from the nearest regional port at Rockhampton (Figure 11).
The Mt Clermont tenement is accessible by well-maintained gravel tracks leading off the nearby bitumen Gregory Highway linking Clermont to Emerald. Access is possible all year except after occasional summer tropical storms when roads may be blocked due to flooding for short periods.
Physiography and climate
The Clermont region that includes the project area comprises a mature continental landscape composed of eroded rounded hills and plains. The climate is subtropical without a distinct dry season, although most rain falls during the summer. The average annual rainfall is about 640 mm (Bureau of Meteorology, 2014).
The Mt Clermont tenement covers predominantly flat, cleared pastoral land dissected by Retro Creek. The district was part of the Brigalow Development Scheme in the 1960s with large-scale clearing of the brigalow scrub by mechanical means. The large new farming blocks opened up by the clearing of the brigalow lent itself to the broad land growing of grain and cereal crops, particularly sunflower and sorghum.
Emerald, 60 km to the southeast, has a humid subtropical climate with hot, relatively wet summers and mild, dry winters. Maximum temperatures range from 34 °C in January to 22 °C in July, while minimums range from 22 °C to 7 °C. The average annual rainfall is 641 mm. The wettest year on record was 1407.2 mm in 1956. Extremes of temperature have ranged from 48.6 °C to −5.6 °C, while the wettest 24 hours on record was 182.0 mm on 25 February 1975.
Impact Minerals carried out exploration at Mt Clermont between 2016 and 2019. This work included mapping and collecting grab samples, RC drilling and an IP geophysical survey along the Retro Fault System to confirm the potential for epithermal mineralisation over its 10 km of strike length (Figure 14 and Figure 15).
At Retro Extended is a gold-bearing quartz reef/vein system. A mineralised vein system was defined by this drilling over 200 m of strike and 75 m depth (Figure 16).
Impact in 2018 and 2019 drilled 17 RC and one diamond hole for a total of 2,843.5 m along the Retro Fault System as well as rock chip and soil geochemistry and IP resistivity and conductivity geophysical surveys. This work extended the total strike of mineralisation at Retro Extended up to 1,200 m and up to 125 m below the surface.
