Some collectors have confused the Håverstad 4 quarry with the Heiegruva. The Håverstad 4 quarry is situated in the south hang of a cliff about 525 SE of the Håverstad farmhouse.

Study of map data clearly confirms the correctness of this.

This means that the Heiegruva has never been correctly registered at Mindat.

Since Håverstad 1-7 are existing quarries, the Heiegruva needs to be listed as nr. 8a, and the prospect Frigstad (1968) described must be Håverstad 8b.

This implies that Frigstad made a mistake calling his locality 4b. But he did not call Håverstad 4a "Tuten" as Stensrud (2009) did.

The Håverstad 3 quarry (Heia) described by Bjørlykke (1934) is a quarry close to the road, north of Håverstad 2, exactly as Bjørlykke (1934) described it.

So it is necessary to distinguish between this one and the Heiegruva.
