The Limestone Prospect comprises an area of variably altered and mineralized limestone which lies to the south and west of the Assmicor Prospect. Geology consists of silty limestone with strong gold-in-soil anomalies occurring in an area of approximately 600 m by 500 m. Artisanal miners previously panned gold from the soils and mined gold from shallow workings in the limestone.



Nineteen surface channel samples were collected Sixteen of these channel samples yielded grades ranging from 0.02 g/t Au to 0.85 g/t Au. Three of the channel samples graded 2.79 g/t Au over 3.7 m, 3.77 g/t Au over 2 m and 1.48 g/t Au over 3 m. The channel samples indicate a zone of anomalous gold above 0.1 g/t in rock samples that extends over an area of 100 by 50 m in oxidized limestone

Mindoro drilled two reconnaissance diamond drill holes, totaling 239 meters, in 1999 in the Limestone prospect area. The holes were drilled to test the down-dip potential of a WNW-trending fault hosted mineralization that was coincident with numerous small-scale surface workings in the East Limestone soil gold anomaly.

Summary results are as follows:

Hole No.	From (m)	To (m)	Length (m)	Gold g/t
99-09	6.00	13.00	7.00	2.70
99-09	53.00	57.00	4.00	0.51
99-10	3.00	11.00	8.00	2.20
99-10	39.20	47.50	8.30	1.30
