After its purchase of the subject EL 5069 on 8/7/2013, a single drilling campaign was undertaken by Iluka Resources during August-October 2013, when 11 RC aircore vertical open holes were drilled for a total penetration of 266.5 m. Ten of the holes were sited ~3.2 km apart along two exploratory drill traverses, and the last, a stratigraphic reconnaissance hole, was sited some distance away in the south of the licence area. No marine sands of the target Pliocene Loxton - Parilla Sands sequence were encountered; instead, all of the holes intersected non-prospective sediments of the estuarine Norwest Bend Formation, overlying the Morgan Limestone. During its tenure of precursor licence EL 3737 prior to 2012, Goldfields Australasia (GFA) drilled 44 exploratory aircore holes on its Haylands prospect as part of a search for possible economic orogenic style gold within bedrock. Only one hole (DEL10ACD001) encountered favourable geology beneath cover, prompting the company to commence diamond drilling that was continued to a depth of 523 m. The majority of the GFA holes were terminated for reasons including prohibitive thickness of Tertiary cover sediments; non-prospective bedrock geology (slate, saprolite); too difficult drilling conditions; and ground water influx issues. Hole DEL10ACD001 returned a gold mineralised bedrock intercept of 1 m @ 0.347 g/t Au. [The results of the GFA exploration program have been previously reported elsewhere - see Envs 11448, 12175 and 12390; but Iluka has appended relevant GFA annual reports to this subsequent final report also]. Iluka collected 2 core samples of the DEL10ACD001 drill core, which was later stored at the DMITRE Core Library, to submit them for petrological thin section examination to investigate the bedrock's potential for "alternative commodities". Both samples were described as sheared and altered andesitic volcanic rock.
