Thank You, I know your jobs and decision making is very difficult. Unfortunately, a pandemic does not come with instructions. This situation has been very difficult for the entire world! appreciate all that you have done, your critical thinking and you long hours that your jobs require. Much gratitude! My reason for contacting you all besides Thanking You is to ask that we come up with a plan to get the back country open. I think emergency services is a critical point, and it does need to be addressed. After this holiday weekend people clearly are going to go into the back country whether they are allowed or not! - am not saying this is ok, it is just clearly a reality. Although I think that we can over come this huge problem. We need to think outside the box! We often use Durango Sheriff department and Durango fire as a resource to help us out in a time of need. Is it possible to come up with a plan to contract with them over the summer months? The fact that we have such a small Sheriff department and emergency service is not going to change, but the fact that people are coming anyway is going to happen. If this were possible it could give Mr Conrad the resources needed to patrol, and it would relieve officers or emergency staff if they were to need quarantined. Please consider this or other avenues to get our back country open.

We are operating under a plan and that is guiding us in our opening and easing restrictions. As you know our resources operate with minimal back up. In the event that a law enforcement officer or first responder are taken out of the rotation we will put in a request for what is called Mutual Aid. This would be either La Plata County Sheriff's Deputies or Durango Fire medics. This is what we do during the 4th of July and are very well practiced with it. The pandemic adds challenges as all services may be experiencing shortages in personnel and may not be able to provide any personnel. Since we are under a State disaster declaration we can request the Colorado National Guard to assist and that is a very real possibility. want to assure you that we are committed to easing restrictions as long as we can keep the citizens of San Juan County safe. thanks Jim On Mon, May 25, 2020 at 6:33 PM Jim Donovan ymd@avyschoo.org> wrote: [Quoted text hidden] Jim Donovan Executive Director PO Box 4 htps./mai.google.comimalluo7k-taseaeb2lesvew-plisearchealapemhnclvead-83A18677109386517870985simpl-msg-A3A166771093865. 1/2 5/26/2020 San Juan County Mail An "Essential Services Train" is coming to Silverton this Thursday!

The COVID 19 pandemic has taken its toll economically, spiritually and physically on both communities that the DSNGRR connects. It is time to make move to re-start our local economy and pivot to "hope". When the time is appropriate, getting the DSNGRR running with paying passengers is an integral part of this re-start for all of us, it is essential to our summer economy especially Blair Street merchants and restaurants. This Thursday May 28th the DSNGRR will be running a special "Essential Services Train" to Silverton. This Diesel Electric powered train will be hauling a flatbed with Emergency Services equipment, food and medical supplies will be loaded onto open air gondola's and an enclosed car. Members of the Harper Family will also be riding up to meet with ICM team and local leadership to discuss potential Silverton based excursions to Elk Part and back and other excursion options. The "Essential Services Train" will arrive in Silverton at just about high noon on Thursday, The single biggest challenge for this project is the appropriate social distancing of the people in Silverton on the trains arrival and knowing what the current group gathering rule will be on Thursday. It is essential that social distancing be adhered for everyone's safety and for the inevitable photographic coverage in the press and on social media. Using "best practice" for COVID 19 mitigation on open air gondola cars pulled by Diesel Electric engines, the D&SNGRR can run this summer with 2 hour excursion trips. Rockwood to Cascade is being considered as a route as well as Silverton to Elk Park and back. At the risk or stating the obvious, Silverton based excursion rides would be a major boost to this summer's economy. To quote John Harper The customers will come to where the train is based out of". Silverton and San Juan County need to show support for the DSNGRR, to send a message to the people and the Governor of Colorado, "we are ready to re-open as we must, and we are ready to do it responsibly when the appropriate time is right". There will be spots marked on the ground 8 foot apart 16 foot away from centerline from the Depot to 12th and Blair to show the public appropriate social distancing. We will have community volunteers proctoring" social distancing, encouraging people to cheer on the trains arrival while being spaced appropriately. This "Essential Services Train" trip loaded with donations of food and PPE will give our community the boost and HOPE" that we all need right now! Ify you have any questions or comments please feel free to reach out directly to me at 970 403-9951.

No.: DV-20-0368 Re: Review of Data Relating to Mayflower Area Water Quality Dear Ms Myers, Knight Piésold has conducted an independent peer review of the data and materials relating to Mayflower Impoundment Nos. 1- 4 and the Mayflower Mill ("Mayflower Facilities") listed in the "Sources of Information" section of my Memorandum: Review of Data Relating to Mayflower Area Water Quality. A copy of my Memorandum is included with this letter. A description of the Mayflower Facilities is provided in the Introduction to my Memorandum, and the Mayflower Facilities' surficial extent is shown in the Map of the Mayflower Facilities, which is set forth in Appendix A of my Memorandum. The Sources of Information includes data generated from investigatory work completed by Formation Environmental on behalf of Sunnyside Gold Corporation ("SGC") during calendar years 2015 2019. It is my understanding that SGC expended more than $10 million on these investigations. I - have no reason to doubt the accuracy of the data generated by these nvestigations. After a review of the Sources of Information, it is my conclusion that there is no evidence indicating that the Mayflower Facilities are the source of anything but negligible metals loading to the Animas River, if any, and there is no evidence identifying any pathway from the Mayflower Facilities toi the Animas River. Groundwater in the Mayflower Mill area is releasing negligible solutes, if any, to the Animas River. In the area of Impoundment Nos. 1 and 2, although seep sample 5000 appears to be a source of solutes to the. Animas River, this seep likely originates from a source other than the Mayflower Impoundments. There is no noteworthy increase in cadmium, copper, or zinc concentrations in the Animas River adjacent to Impoundment No. 3, suggesting negligible right bank discharge of solutes to the Animas River along this reach. Metals increases in the Animas River along the reach roughly adjacent to Impoundment No. 4 are likely sourced from seep 6150. The discharge from seep 6150 does not originate from mpoundment No. 4 or the Mayflower Facilities.

Re: Review of Data Relating to Maytlower Area Water Quality 1.0 NTRODUCTION At the request of Sunnyside Gold Corporation (SGC), Knight Piésold and Co. was retained to provide an independent peer review of the Mayflower Area geochemistry. A map depicting the surficial extent of Mayflower Impoundment Nos. 1 - 4 and the Mayflower Mill (collectively referred to as the "Mayflower Facilities") is set forth in Appendix A. The Study Area (shown on Figure 1-2 in Formation, 2020) is located in the Animas River valley and extends from just upstream of the confluence of the Animas River and Arrastra Creek downstream to the 14th Street bridge crossing in Silverton. The review consisted of analyzing data and information and providing an opinion regarding the extent to which tailings or other potential source materials within the Mayflower Facilities contribute to metal loadings to the Animas River. David Bird, a geochemist with extensive experience (+30 years) in mining geochemistry, but no prior experience working specifically on the Mayflower Facilities, conducted the review. A copy ofMr. Bird's CV is attached as Appendix B. Knight Piésold's ISO-9001 quality program provides for the use of Technical Memoranda to transmit preliminary versions of data, conclusions, and recommendations. At Client's request, this format has been used to convey a final version of the deliverable, which represents a variance to Knight Piésold's quality procedures. The variance was approved on March 20, 2020 by Paul W. Ridlen, President, Knight Piésold and Co. 2.0 HISTORICAL ENVIRONMENTAL IMPACTS The history of mining in San Juan County spans a period of 120 years from 1871 to 1991, and mining throughout this period caused adverse environmental impacts to the Animas River watershed. The historical environmental impacts to the Animas watershed since 1871 are still visible today and are key to understanding adverse impacts to the Animas watershed. Historical impacts to the watershed were somewhat unique to the time frame in which the mining occurred. The mining eras are categorized as follows (Jones, 2008), and each carried a specific environmental signature: 1. Smelting Era (1871-1889). The first era of mining from 1871-1889, known as the Smelting Era, targeted only higher grade silver-lead ores. The crude mining methods of the time resulted in highly mineralized lead-silver waste rock left on surface dumps, which were likely sources of metals dissolved and mobilized by surface water and groundwater with eventual deposition to the Animas River fluvial system. Mill tailings produced during this era were discharged directly into the closest stream, where Management System Certifedby: ISO ISO OHSAS 9001 14001 18001 Knight Piésold and Co 1999 Broadway, Suite 900 Denver, CO 80202-5706 Qualty Lnegem anagement EAE T +1 303 629 8788 - E: denver@knighipiesald, .com I www. knightpiesold.com Managerent Knight Piésold CONSULTIN G facility in the area of TP-4. Although the metals content of the fluvial materials has not been characterized, it is reasonable to assume that the combined sediment-tallings deposit contains masses of metals similar to other fluvial tailings in the watershed. Yearly investigations conducted by Formation Environmental ("Formation") since 2015 document a minimum of 12 right bank discharges to the Animas River in the Study Area, some of which discharge elevated solute concentrations, including 4353A, 4353C, 5000, 6150, and 7690. Formation has also documented a minimum of 3 left bank discharges in the Study Area. However, due to access restrictions the characterization of left bank discharges is not complete. It is significant to this study that there are more documented workings and mineralization on the south side of the river (left bank) than on the north side (right bank), as shown on Figure 2.

There is no noteworthy increase in cadmium, copper, or zinc concentrations along this reach of the Animas River according to the data in Formation (2019). In fact, copper decreased along this reach in all three samples (March, June, September), while cadmium decreased in March and held steady in June. Zinc showed an increase in March and September, but the increase was slight. Only one right bank seep is documented, sample 5608, but this site is a drainage ditch and more likely representative of surface water than groundwater. The one groundwater sample collected in 2018 from the tailings (MW-26) carries higher solute concentrations and lower pH than seep 5608. However, radar diagrams for the two samples show no similarity (Figure 4), indicating that the source of solutes to seep 5608 is not the Mayflower Facilities tailings in the vicinity of MW-26.

The photograph (Figure 7) demonstrates an example of the metal-laden fluvial tailings that were deposited in the watershed in the period 1871-1935. Elevated metals concentrations in sample OP-37 relative to background are reported in Formation (2019). The fluvial tailings are distributed in the watershed and outcrop in the Study Area near seep sample 6150. It makes sense that this same material is present at seep sample 6150 and is responsible for the elevated solute concentrations in 6150. Figure 7 - Historical fluvial tailings outcropping near seep sample 6150 Finally, isotopic data suggests different origins for 6150 and the groundwater samples, specifically the tritium signature. Tritium data suggest that 6150 is more reminiscent of surface water than groundwater (Table 1). It is not straightforward to resolve how this could occur, but perhaps river water occasionally infiltrates the riverbank during periods when the reach is losing, then re-emerges at sample site 6150, picking up solutes.
