To Whom it may Concern — RE: Recommendation of Big Sky Exploration, LLC diamond drillers.

As Vice President, Exploration for Timberline Resources Corporation I am pleased to offer this strong recommendation for the diamond drilling services of Big Sky Exploration, LLC (BSE) as led by Mr. Ben Seiben.

Timberline Resources is in repeat contract engagement with BSE for several thousand meters of core drilling on our northern Nevada exploration program. BSE’s drilling of PQ, HQ, and occasionally NQ core has been beyond expectation in production with consistently excellent recovery in difficult, broken, often highly altered rock all under sometimes difficult site (including winter) conditions.

BSE operates efficiently with a safety-first approach. They run a well-organized and clean operation and are resourceful problem-solvers. They willingly engage and implement modern mud technologies and engineering leading to excellent production and recovery success for Timberline. Their connections to suppliers are excellent; they have managed to avoid shortages even through the current challenging supply chain environment.

I appreciate BSE’s particular attention to coordinate with our geologists to develop an understanding of the rock character of our particular stratigraphy and structural zones. They have also developed and maintain excellent relationships with our RC drillers allowing a seamless, efficient coordination from RC pre-collar to core drilling.

In summary, BSE provides a high quality, very cost-effective, and efficient core drilling service. I highly recommend them and consider them to be our first choice core driller as our exploration programs advance.

Dear Ben,

I want to thank you and Adam for the excellent work you did for Golden Hill Mining at the FAD property in Eureka Nevada. I was a hard sell for you at first but after looking at the poor performance of other drill companies out at the property and talking to some of your other clients I was persuaded to give you a try. I am glad I did.

In the short few months before the takeover of the property by i80 gold you drilled 4 holes for over eight thousand feet at an average direct drill cost of about $93 per foot. More so, the recoveries achieved under some difficult conditions were excellent. Although my tenure at FAD has been cut short I understand one of the holes you drilled through the mineralized zone contained recoveries of better than 80% in soft friable massive sulfide material. I am pleased by that.

These numbers are far far better than other drill companies I have used in the past and I will certainly be requesting bids from you on my next drill campaign. Please use this as a letter of recommendation for potential clients.

Best of luck to you and Adam and stay in touch.
