2.0      DESCRIPTION OF EXISTING CONDITIONS
2.1    Geology
The 1:100,000 scale Gympie Surface Geology Map (Sheet 9445) indicates that the site is underlain by early
to middle Triassic age phyllite (Rk) of the Kin Kin beds. A fault (black line) is indicated on the mapping at the
southern end of the property approximately 150 m south of the proposed shed site. An extract from the
geological map is shown in Text Figure 3.

Text Figure 3: Extract from geological map
At the time of the assessment, the shed pad cutting ranged up to about 3.0 m deep and typically exposed
residual clays up to 0.3 m below ground level (BGL), overlying very low to low strength phyllite tending
towards medium strength with depth. Text Figure 4 below shows the cut batter at the time of the
assessment.
