A huge jump in lithium prices drove the value of spodumene concentrate sales to a record $6.8 billion - more than two-and-a-half times its previous record and elevating it to WA's third highest mineral by sales value.

LNG production was valued at an all-time high of $38 billion and condensate production was valued at a record $8.6 billion.

Against the backdrop of crippling labour shortages, the number of people employed in WA's resources sector also hit a record high of more than 157,700 people, up 6% year-on-year.

Mineral exploration expenditure reached a new high of $2.5 billion with strong levels of spending on gold, nickel, copper, rare earths and lithium.

More than $24 billion was invested in WA's mining and petroleum sector - the highest level since 2016.

WA has around $57 billion of resources projects under development and a further $87 billion in medium and longer-term projects in the pipeline.
