Dec 07, 2005 (G Seim) - Alamo Hole 1 cased through 130 ft. of overburden and collared in a fucshite-sericite schist, interpreted to be a metasomatized felsic to intermediate volcanic tuff. 4 chert horizons with interlayered chert were intersected. Some of the chert was carbonaceous. Some beds of the chert were brecciated and had a chlorite-pyrite matrix between the chert fragments. Pyrite averaged 6% to 10 % in the chert horizons and 1-2% in the schist. Fuchsite content diminished with depth and is not present beyond the deepest chert horizon. Volcanically derived sediments occur at the bottom of the hole.

Dec 07, 2005 (G Seim) - Exploration diamond drilling by Alamo Petroleum in 1975 resulted in DDH1 intersecting strongly altered rocks (fuschite schist) intercalated with porphyritic intrusions, sediments, and intermediate tuffaceous rocks. In addition, 4 chert-pyrite iron formations were intersected which contained anomalous values of zinc and copper. The highest zinc value was 0.42% Zn, 0.03% Cu / 1ft, hosted by a sulphide iron formation. Many other anomalous copper (100-700ppm) and zinc (1000-2300 ppm) values were intersected by this drill hole as well.
