color changes, sound, lights on and off

At Approximated 2200 hrs, at date stated above, during a prospecting venture, and bedding down for the night, myself and 2 partners, noticed a bright light coming in from the north, at first we thought it was an aircraft, as it approached closer, there was no sound, as it leveled off, approximatey a quater mile from our campsite, it remained motionless, the approximate size was 50-100 ft. this is a guess, but as it remained in mid-air, it released another object from its bottom, which looked like a big ball, the ball starting circleing the craft, and then started our way, all of us stood by the campfire watching, the larger craft, started our way also, as it got closer, the ball, gained altitude and went in a northern direction, the larger object, then passed over us, and made 3 passes in about a 100-200 yard circle it was approximated 500 ft, off the ground , we could see that it was circular, and it seemed to wobble, a little, at that point the object went about 200 yards south of our position, and began to decend, it did not land, but it changed colors, from an dull blue to orange, it then gained altitude, came over us again, circled, and then we could hear a low huming sound, it was approximated 200 feet, above our camp, we all watched, my 1 companion started praying, my brother started praying also, I was fascinated, and watched, I moved to a position, out of the camp fire glare, and watched, My friend started to run, my brother right behind him, after that, the craft gained altitude, and went in a southern direction, my brother/friend returned to the campsite, and we talked about this, my friend, and my brother, both reported this to the minister of there choice, I did not report this incident for fear of being classified, unstable, or other excuses, I have kept quite for many years, but I thought I might share this with those who are searching for an answer.
Date and time may be approximate.  PD
