If you read the above article you will see that the Aurora Company "failed to get off the ground" so to speak.
Hensher and Co. did discover payable gold.
However, the ground had already been 'claimed' and held by two other companies (the New Union Jack Company and the New Wellington). Therefore the ground could not be 'pegged' and the Aurora Company could not establish a claim and begin mining.
With speculation in the Company and the discovery shares were offered and 'snapped up' however not within the laws of mining of the day. Investors demanded their money to be refunded.

There is no Aurora Company registered in the year of 1881 in the Victorian Government Gazette.

Bendigo Advertiser, Thursday 14th April 1881, Page 3, Raywood.
A party at Elysian Flat, who are prospecting for Hensher and Co., have come on quartz with gold in it, which, should it prove payable, will open out quite a new field. The claim is situate about a quarter of a mile north of the Shamrock Hotel, the depth from which the prospect was obtained was 46 feet, and just below the old alluvial.

Newspaper - Empire (Syndey NSW) Saturday 19th June 1852, page 2. Portland Shipping.

Arrivals. - (June 2) Runnymede, barque, 408 tons, James Brown, master, from Liverpool 23rd February. No cargo or mail. Passengers - Surgeon-Superintendent, and 212 immigrants.
Squatters be of good cheer. - We learn from our last files of English papers, and the information is fully confirmed by the arrival of the Runnymede, emigrant ship, in our Bay, yesterday morning, with 212 immigrants, that the Emma Eugenia, 388 tons, another vessel for Portland direct, may be immediately expected in our harbour with a large complement of both sexes, all  of whom belong to the labouring classes; thus the lack of servants for the interior will be supplied most opportunity; not only so, but a regular succession of emigrant vessels will, from time to time, continue to arrive, freighted with the very description of labour that the colony, and our portion of it in particular,most pressingly requires. We have thus the gratifying assurance that settlers will, in a brief time, have their necessities supplied adequate to their wishes, ardent, urgent, and numerous as they are. The Runnymede, on leaving this , is bound for Bombay: her stay will not be protracted here. The Collector's destination is Melbourne, not Portland, as formerly intimated. This circumstance is immaterial, in consequence of the above named barque bringing the immigrants who were expected about this date, and who are safely anchored in our spacious bay.  Since the above was in type, we learn that the Runnymede had to continued with baffling winds for nearly a month, abreast of Kangaroo Island, otherwise she would  have made a passage unprecedently rapid.
The passengers unite in bearing unequivocal testimony to the uniform kindness of the captain as a gentleman, and his judgment as a mariner: and to the skill, humane deportment, and attention of the Surgeon-Superintendent, professionally.   And, on the other hand, Captain Brown and the Doctor record, with pleasure, the good conduct of the immigrants. - Portland Herald.
