PROSTAR HOLDINGS, INC. (TSXV-MAPS; OTCQBMAPPF) – “THE GOOGLE EARTH OF THE UNDERGROUND” From an infrastructure company serving the Canadian energy sector, we move to one of the more interesting individual stories I’ve ever heard: one that is transforming construction, utilities and more by being a state-of-the-art infrastructure company that bills itself as “The Google Earth of the Underground.”

I want to again thank my friend Paul McKenzie— President of NexOptic Technologies (TSXV-NXO; OTCQBNXOPF), one of my other story stocks (in high-tech lens technology/optics and A.I.) which will be featured separately in another Special Report in the coming weeks—for first bringing Colorado-based (with offices in Boulder and Grand Junction) ProStar to my attention. That was ahead of its I.P.O. back earlier this year, giving me time to “kick the tires” and get to know the story.

Especially with ever more infrastructure activity and spending set to take place in the coming years, most anything that moves the needle on cost savings and greater efficiencies has a bright future.

But I have to tell you that when I learned and began to digest ProStar's story, technology, considerable business progress already and more, I was quite blown away!

We've all seen scenes like the one at right; maybe even on our own street or property in the past.

Before many kinds of construction, utility, road and other work can begin, contractors, engineers, etc. must know where underground power, gas and other lines are located. The trouble is, the methods technologically for doing this are quite antiquated; often, beginning with YEARS-old, hard copy "maps." And that leads to accidents of one kind or another many times daily some place or other, when these underground lines are damaged. Indeed, as you see at left, the cost of these accidents is enormous.

As I learned the story, it amazed me that there has not been a more precise way to locate these underground lines of various kinds previously. But ProStar has it; and backed by 20 patents (and counting) and in partnership now with Trimble Navigation (NASD-TRMB), one of THE The National Investor – Fall, 2021

premier infrastructure and engineering companies in America. At the company’s web site (at https://www.prostarcorp.com/) you’ll learn much more about its PointMan system. No flags. No spray paint. No accidents multiple times daily. But what contractors DO have is a state-of-the-art technology that allows them to pinpoint underground structures, lines, etc. to the centimeter.

The company's technology is being endorsed and embraced rapidly. The State of Colorado now mandates that no state-funded infrastructure work may proceed without those in charge using PointMan. Other municipalities are following: most recently, the Township of Aberdeen, New Jersey adopted PointMan as its system of record (SOR) to meet the New Jersey Department of Environmental Protection (NJDEP) mandate for Mapping and Digital Data Standards.

Getting back to ProStar’s tie-up with $22 billion market cap Trimble, this is going to be a BIG part of ProStar’s accelerating journey to really monetizing its technology…and getting the markets’ attention. Last December, ProStar announced (at https://www.prostarcorp.com/prostarsuccessfully-completes-integration-with-trimblereceivers/, ahead of its public market debut, that it had completed its platform's integration with Trimble's receivers (the original tie-up with Trimble was first announced last Summer.) So now, ProStar is available through Trimble's dealer network as well. Engineers, contractors, etc. can buy ProStar's app straight from Trimble; and those customers are not Trimble's clients, but ProStar's.

While at ProStar’s site, I urge you (besides getting on their own mailing list; something you should do for each of the companies in here!) to spend some time looking at all their news from 2021, as they build critical mass (and business.) Especially check out, though, the item from September 1 (https://www.prostarcorp.com/prostar-named-one-ofthe-5-best-saas-solution-providers-to-watch-2021/) where the company was featured as one of the year’s Top 5 Saas (Software as a Service) providers to watch.

It’s notable that even now—with Washington fiddling still over infrastructure spending— ProStar is growing more rapidly without this “help.” This is yet another “under the radar” company— with a market cap of a mere C$40 million recently—that won’t be down here for long, I.M.O.

TIPS ON BUYING COMPANIES “RIGHT” One quick note before the main closing subject here…

I encourage each of you reading this to get to know more about the companies herein. I have done my darnedest to, first, make the “macro case” as best, honestly and effectively as I can. And in their own ways, these companies (and others I cover in The National Investor) “fit the bill” in one way or another.

Kick the tires (as I do.) Visit their sites. Follow them on social media. Get on their email lists so that, when news comes out, you’ll KNOW IT.

And make sure if you are not already you are on MY various lists, etc. as well. Not only via email, but… * On Twitter, at https://twitter.com/NatInvestor * On Facebook at https://www.facebook.com/TheNationalInvestor * On Linked In at https://www.linkedin.com/in/chris-temple-1a482020/ * On my You Tube channel, at https://www.youtube.com/c/ChrisTemple (MAKE SURE TO SUBSCRIBE!)

Among other things, Yours truly will from time to time send out updates on these companies when I feel the situation calls for it as well! ______________________________________________________________________

ADDITIONAL LOGISTICAL TIPS FOR U.S. BASED INVESTORS Relative to investors in just about every other country, Americans live fairly sheltered lives.

Elsewhere, if you have a garden variety brokerage account, it’s old hat to buy shares of companies on numerous other exchanges. But where U.S.-based brokerages are concerned for U.S. investors, it’s not as easy; and it just got a little harder.

Some of you reading this are already experienced with how to overcome these inconveniences in order to buy some of the companies in here (and others.) If so, you need read no farther. But for those who do not have that knowledge and comfort level, let my demystify things for you.

For companies listed in Canada, Australia, etc. it is generally BEST to buy them via one of the few U.S. brokerage accounts that DO allow you to buy shares on foreign bourses (either directly or by doing the currency conversion first and actually holding other currencies in you account as a first matter.) For my purposes, I use Interactive Brokers (not a pitch for them and they pay me nothing; just a friendly heads up.)

These days, if you have a U.S. brokerage account, you generally CAN buy foreign stocks IF they at least have an OTCQB or OTCQX listing. A new S.E.C. rule that just went into effect last month now pretty much prohibits a U.S. investor from buying stocks that only have a corollary trading symbol The National Investor – Fall, 2021

on the OTC “grey market” (sometimes euphemistically referred to still as the “pink sheets” named for the physical weekly ledger I am old enough to remember that updated us on prices of non-exchange public companies.)

So for those of you who have followed this development, you know already that foreign companies that want to keep ease of trading in the U.S. have been scrambling to get those QB or QX listings of late!

For those that have not as of yet (on the list of companies herein that is AirTest, BacTech and Enterprise Group) they will be forthcoming.

For any others, in most cases there is sufficient daily volume on the QB and QX to enable you.
