Chapter Info

Additional Information


 As stated on our HOME page, the Au Mojave Prospectors of Hesperia,CA.  Inc. (aka: AuMP). We are a non-profit 501(c)(7) & we were formed as a  chapter of the Gold Prospectors Association of America (aka: GPAA) on  December 14, 2002 by 18 local GPAA members that got together to  establish the Hesperia, CA. chapter. 

   The AuMP meeting information is on the HOME page as to the place and  time and there is NEVER any dues or fees to attend a meeting or  function. We are a family oriented club, be sure to bring your children  as they are our prospecting future. Our meetings run between 1 - 1.5  hrs, unless we have a speaker.

   Our intent is to educate the public on the various ways to prospect as a Small Scale Miner  and to be a responsible steward of our lands. Besides participating in  GPAA events, we also have booths (generally we have a panning  demonstration, sell GOLD concentrates and give out chapter information)  at various events held by the towns and clubs in the high desert area.  

  The following are some of the Small Scale Miner operations  we are active with: Panning. dry washing, high bankers (which requires a  tub of water), metal detecting ( Gold, Coin and relic shooting) and  sluicing. Members have traveled to areas to legally DREDGE, until we are  allowed to DREDGE again in California.

   Lately there has been an increasing number of members that have shown  an interest in hunting for other minerals, such as semi precious rocks and  gems, they could get lucky and find high quality gems!   

   As a non-profit 501(c)(7) we are required to donate to a charity. We  have chosen the Happy Trails Children’s Foundation, located at 10755  Apple Valley Rd, Apple Valley, CA. 92308  

   Their History:  The Victor Valley Child Abuse Task Force was formed in  1982 with the mission of stemming a rising tide of child abuse, neglect,  abandonment and death in the High Desert of San Bernardino County in  Southern California.  In 1992, the name was changed to the Happy Trails  Children’s Foundation, to reflect the participation and support of Roy  Rogers and Dale Evans, King of the Cowboys and Queen of the West.

 Au Mojave chapter has one claim consisting of 60 acres which can be used by chapter members and a coalition of 7 chapter members that has a 40 acre claim that can be used by AuMP members as long as one of the claim holders is on the claim. Both claims are located in the Coolgardie area which is north west of Barstow, CA.     AuMP also has a GPAA claim called the  Little Crystal located south west in Hesperia, CA.
