Information regarding the success of the mining project of this expedition is almost totally lacking, but it seems certain that nothing was done to discover the hoped-for gold mines. The climate affected the men so adversely, that it is altogether unlikely that they even attempted to look for the mines. The small cargo carried back by the various ships, most of which seems to have been on the "Amity," probably represents the only tangible results of the expedition. These goods, consisting of elephants' teeth, wax and hides sold for L1,567.8s.,[8] whereas the outlay for the expedition was probably between L4,000 and L4,500.[9] This sum does not include L2,640.8s.8d. expense which was incurred to send another of the king's ships, the "Blackamoor," to the Gold Coast, in June, 1661.[10] The "Blackamoor" was followed in April, 1662, by the "Swallow" which, together with its cargo, cost the Royal Adventurers L1,l01.2s.ld.[11] Later in the year the three ships, "Charles," "James" and "Mary," were sent to the Gold Coast at an expense of about L5,000.[12] By September, 1662, L17,400 had been subscribed by various persons to obtain the cargoes for the ships which had been dispatched to the coast of Guinea. Of this amount L800 had been promised by the king; L3,600 by the duke of York; L400 by the queen Mother; L400 by the duchess of Orleans; L800 by Prince Rupert; and L800 by the duke of Buckingham. Of the L17,400 subscribed all but about L1,000 had been paid by October 20, 1662. From this investment the company had received no returns except the L1,567.8s. from the first expedition, while the three last vessels, the "Charles," "James" and "Mary" had not yet arrived at the Gold Coast on their ill-fated voyage.[13] Up to this time there had been no uniformity about the amounts invested, and no definite times at which the several amounts subscribed, were due. It was assumed that money would be forthcoming from the members whenever it was needed to dispatch ships to the coast. About the middle of September, 1662, it was decided to pursue a more businesslike policy. A list of subscribers for shares at four hundred pounds each was opened, and by the 15th of January, 1663, the amount of this second subscription was L17,000.[14] The stimulus for obtaining this added subscription was the fact that, at the same time, the company was agitating for a new charter, which was granted by the king, January 10, 1663.[15]
