This expedition excited great hopes amongst the settlers, who found most of the horses and provisions.

The party left Lefroy's station of Welbing on the 9th of September, with ten pack, and two riding-horses, but did not succeed in penetrating any distance beyond the Murchison, being turned back at all points, after repeated efforts, by the belt of impervious scrub between the Murchison and Gascoyne.

They therefore returned without seeing the latter river, after having attained a distance of 350 miles from Perth; but they succeeded in finding a considerable extent of available country, both pastoral and agricultural, and in discovering a vein of galena on the Murchison.

They re-entered Perth on the 17th of November.
The following month, Gregory, Bland, and three soldiers of the 96th accompanied Governor Fitzgerald by sea to Champion Bay to examine the new mineral discoveries.

The galena lode was found to be more important than had been at first supposed.
