Most discoveries are evident at some point in time, quite often, the turning point is the first drill hole. Back in 1975, scores of geologists from around the world requested reprints of this paper. Back then, photocopiers were not widespread. This response, and the author's frustration of never having enough funds to drill motivated him to create the Beep Mat. Thus, one can trench the near surface targets, and reserve diamond drilling for the ones buried deep.</p> 345<p>Read more : <a href="/pdf/articles/stop-sreening-start-drilling.pdf" target="_blank">Stop screening- Start drilling!</a> 346</p> 347 </div> 348 349 350 </div> 351 </div> 352 353 354 </div> 355 356 </div> 357 358 </div> 359 360 <hr class="clearer"> 361 362 <div id="colophon"> 363 364 <div class="container"> 365 366 <div class="row"> 367 368 <div class="span9"> 369 370 <h3>Contact Us</h3> 371 <div class="row-fluid"> 372 373 <div class="span4"> 374 <h4>@ Email Us</h4> 375 <p>Marketing: <a href="mailto:[email protected]">[email protected]</a><br> 376 Support: <a href="mailto:[email protected]">[email protected]</a></p> <p><a href="/contact">> Contact form</a></p> 377 </div> 378 379 <div class="span4"> 380 <p>Phone: <a href="tel:+1(418)478-5469">+1(418) 478-5469</a><br> 381 </p> 382 <p class="notif"> Monday thru Friday. 9 AM to 5 PM.
