Can reveal whether the recipient New metal in the soil?

You do not need powerful TX (no benefit from power here), but you need good sine wave TX and noise will not be big problem.
As J_P explain this receiver is designed to experiment and play around with directive (ferrite antenna) receiver.
There are theoretical possibilities to detect reflected wave from very big metal surfaces no matter if it is New metal or Old metal.
But you do not expect to detect on remote small targets as one coin alone (buried or in air). Such intention already encroaches sphere of dowsing and not simple electronic design like this.
