Petri put the maps lying on the passenger seat into a box on the back of the utility to make room. The two men squeezed in and he started the engine. With a wave to the rest of the group he did a U-turn in the sand and headed east.
Conversation in the cabin was not easy at the best of times because of engine noise but the two men said little in response to questions. Petri had to say, ‘Excuse me, what was that?’ so many times because of the men’s strong accents that eventually he just drove without speaking and his passengers likewise remained silent.
When they arrived, Petri was surprised at the size of the place. In conversation with some of the men he discovered that the settlement had a school, small hospital and acted as a centre for many of the local people, displaced by activities of farming, mining and new laws of land ownership. One of the older men explained that there were people there from many different groups and he described them as ‘People of the Spinifex’, coming from different remote desert areas and bringing with them a variety of dialects and languages. Some spoke a little English but most only their local dialect. Quite commonly communication was by way of sign language or dance.
As it turned out, the whole episode was serendipitous as Petri was able to meet up with some of the people who regarded the land on which he was working as their responsibility. He was introduced to some elders of the Wankatja people and this gave him an opportunity to explain why he was there and what he was doing. Even though it was designated ‘Crown Land,’ Petri knew that these elders regarded themselves its custodians. When they asked what he was doing there he explained his regional exploration program. The older men he met were interested but warned him there were places sacred to them and he should avoid going there. Petri asked for permission to camp nearby and meet again for more detailed discussions in the morning. Knowing which areas to avoid would be useful information for him, not to mention an important courtesy. The men agreed to his request.
When Petri arrived back at the Mission early the next morning the meeting was already in progress. He waved and received a wave in return but no invitation to join the discussions. A shady spot beckoned so he sat down and waited. As time passed he found himself scratching patterns in the sand, doodling in his notebook and thinking that he should be on his way. He stood, walked around impatiently and returned to his shady spot. He was almost ready to pack up and leave when one of the older men came across and invited him to join the circle.
The meeting differed from those Petri was accustomed to in his dealings with AGO or Spex. Here, it was not a case of the majority rules, or a decision by the senior management, but a case of finding a consensus. The group explained again to Petri that there was no objection to his working in their land but there were some places he should not go because they were of special significance.
Petri asked, ‘How will I know where they are?’
One of the men, grey haired and with dark eyes set in a heavily wrinkled face, asked to see his maps. Around him crowded several others, all of indeterminate age but clearly older than the young men who stayed at a respectful distance. Petri unrolled his maps and placed a collection of the aerial photographs on the ground.
‘Okay. If you can show me on the map where I must not sample then I’ll avoid those areas.’ He pointed to the Mission. ‘This is where we are now, so’s you can get your bearings.’
The old man shook his head, ‘No, some places secret. You show me your places and I say yes or no.’
‘Oh! That’s not quite so easy. Some places I haven’t fixed yet. It depends on how accessible they are. Here, where the black numbers are, is where I’ve already collected.’
The elder looked at the map.
Petri continued. ‘I’m sorry if any of them are in places I shouldn’t have gone, but I didn’t think. Or know.’
After a study of the map, comparing it with the photographs, the elder said, ‘No. It’s okay. No problem.’
‘What about the places I still want to go? I’ve marked them with these little circles but the actual sample might be taken further up or down-stream. Depends on how easy to get there.’
This time several men looked at the map, pointing and talking among themselves. Eventually the same man nodded and said, ‘No problems.’
‘Great, that makes it easier.’
‘But this one,’ the old man pointed to one of the circles, ‘Ya take care. Steep bank to creek an’ could roll. Better come in ‘ere.’ He traced an alternate route for easier access.
‘Thanks, I’ll do that. I appreciate your help.’
One collection point was close to an area, which, on the aerial photographs, looked like another small settlement. According to the maps it was in the nature reserve and there should be no agricultural activity there.
Petri queried this and Tommy told him. ‘It’s very old place, long time ‘go, work for CSIRO.’ Everyone knew the acronym for the Commonwealth Scientific and Industrial Research Organisation. Tommy went on. ‘White fellas there now. Keepin’ bees. Makin’ honey. We don’ go there. Big fence all round. Them fellas chase us. One has gun so we stays aw
ay. Only once, ‘bout two years ago, his wife had baby an’ he come an’ he ask Jenny for help.’ He pointed to a group of women sitting apart from the men. ‘Jenny don’ talk much, she’s like speckled bird, don’ b’long, but good for babies comin’.’
It was close to midday by the time all of the sampling sites had been dealt with and the areas approved. Petri rolled up his maps and stacked the photographs, thanked the group for their help and, with handshakes all round, got back into his Toyota.
‘Ya wanna stay for lunch?’ asked Tommy.
‘Thanks, but I really need to get moving. Many thanks for all your help.’
‘No worries. Thanks for ya helpin’ for us.’
Resuming his delayed journey to Kalgoorlie. On the way back he passed the yellow Holden ute being towed towards Cundeelee by an equally battered looking brown Holden ute. They passed each other with just a friendly wave.
P etri took very little time off during the Christmas break. The summer heat made it too difficult to continue his work in the West Australian desert, so he went through the laboratory results. These were mixed, though promising. By plotting them on maps it was clear that some areas were worthy of further investigation. Further detailed sampling would be necessary at several points. One of the most important sampling sites lay on a sand-filled river channel that passed close to the old CSIRO station.
The results from the chemist were less promising. It seemed that the high salt content of the ground water was still causing problems with extracting dissolved gold. The report given to Petri indicated that the high salinity of the ground water was causing precipitation of magnesium salts in the pipes, which carried the gold-enriched liquids back up to the surface, more rapidly than anticipated. This encrustation in the pipes reduced the flow of gold-enriched liquids to a trickle. Petri took comfort in the final conclusion that ‘work is continuing and it is hoped that a resolution to the problem of precipitation of magnesium chloride and other salts in the pipes will be found in the near future.’
Prior to his next field excursion Petri he needed to find out more about the CSIRO station. The men at Cundeelee indicated that the occupants there were both armed and ‘unfriendly’. As a geologist on legitimate business Petri had every legal right to enter property, public or private. But having a legal right and overcoming local property owner’s aggression are two different things. Diplomacy is one of the skills acquired by most exploration geologists. Being armed with accurate information would prepare him for any likely debate in the field. He headed for the suburb of Wembley and the CSIRO laboratories. It took some time to find somebody who knew about the remote station at the edge of the western margin of the Great Victorian Desert. At last found an elderly scientist who knew something.
