Maybe you are not aware there was a Presidential election in Mexico July 12.
When USA has an election Nov 6 there is often political impasse until new govt is in power-called a lameduck situation.
Bob already discussed this as a reason for the delay. Have u ever heard the expression "its Mexico?"
So why do miners mine there-because there are a lot of minerals and costs are much lower than in the U.S. or Canada.

Remember the Bush Gore election and the U.S. Supreme court deciding the election?
Well there was a court challenge to the new govt in Mexico which was  only decided Aug 30.
Plus whatever transition period normally prevails as a new group of politicos take over jobs and set up their networks. The Mex govt instituted an unprecedented series of extra audits for exporters after the new 2012 permits were issued and that didnt involve a change of govt. So dont automatically assume there is some game by the company. These Mex govt problems are part of the otherwise much lower cost of doing business in Mexico vis a vis the USA and Canada.

Request to Invalidate Election On July 12, López Obrador presented his formal complaint to invalidate the election to the Electoral Tribunal of the Federal Judiciary on grounds of violation of constitutional article 41 which states that the elections must be free and authentic and with equal benefits for all competing parties.[61] Alleging that the Mexican media had treated them with inequality in relation to Peña Nieto and presenting the numerous evidence of paraphernalia used to buy votes for the PRI as well as pre-marked ballots and notarized witness statements of people who sold their votes to the PRI.[62]The complaint also pointed towards the PRI's campaign going over budget an alleged 1000% over the established allowed budget by the Federal Electoral Institute which is of 336 million Mexican pesos.[63]On July 18 López Obrador accused Peña Nieto of using illicit funds and money laundering to finance his campaign.[64]After presenting new audio evidence regarding the PRI's use of Monex cards, López Obrador commented that it would be better if the Electoral Tribunal invalidated the election and move in an interim President than to violate the constitution and acting in an "anti-democratic" way. He said that if the Electoral Tribunal does not invalidate the election, Mexico will be governed by a "gang of evildoers".[65] On 30 August 2012, the TEPJF, Mexico's highest election-law court rejected the allegations of fraud after they concluded that there was "insufficient evidence of wrongdoing."[66] Post-electoral protests and claims of fraud After the preliminary results of the Federal Electoral Institute announced Enrique Peña Nieto as virtual President-elect, several student protests led by the youth movement Yo Soy 132 and independent citizen movements, have broken out throughout the country claiming the forced imposition of a President and electoral fraud,[67][68][69][70][71][72] as evidence of an alleged fraud has surfaced and pointed towards the PRI buying votes by providing voting citizens with store credit cards of Mexican supermarket chain Soriana.[73][74] Further alleged evidence arose as pictures of ballots already marked in favor of the PRI, with the logo of the party printed over the marking, have been shared widely over online social networks, [75] and there have also been numerous videos and photos of that show the irregularities between local ballot boxes and the official result of those ballot boxes.[76]. More allegations appeared as videos showing protection of local police patrols protecting supposed "Mapaches". Following a request from Andrés Manuel López Obrador, the Federal Electoral Institute agreed to recount more than half of the ballots cast in the presidential election. It later reconfirmed the original result.[77] The result was endorsed by Barack Obama, the president of the United States, and by the Venezuelan president Hugo Chávez, who backed López Obrador in a similar dispute in 2006.[77] On July 7, a national protest in opposition of Enrique Peña Nieto was organized through online social networks, and demonstrations occurred in several cities. The protest in Mexico City was billed as a "mega-march", but the number of demonstrators equalled only around half the number which attended anti-PRI demonstrations held prior to the election.[77] Statements from the Yo Soy 132 student movement formally uninvolved themselves from the protest cautioning against violent results; alleging that it may have been organized by a similarly named movement linked to the PRI.[78] Despite the statement the protests effectively took place in 37 cities in Mexico, Canada, The United States, and Europe[79] with no incidents of violence or known involvement of the PRI. Though in Xalapa, Veracruz a man identified as Juan Pablo Frianzoni, presumed member of the youth PRI group "Juventud Dinamica"; threw chairs at the protesters and then pointed a handgun at them from his balcony. Frianzoni was then apprehended by Police officers who were standing by the protest.[80] Televisa did not broadcast the National protests, and instead presented a live broadcast of Eugenio Derbez and Alessandra Rosaldo's wedding which was interrupted due to "technical difficulties" when loud protest chants became audible outside of the event.[81]Derbez however stated that he was in support of the protests, and though he regrets them happening on the day of his wedding; he said he will cherish the memory.[82] As of July 15[83] protests and further acts of civil resistance against Peña Nieto and Televisa continue around the country.[84]On July 27 protesters set up a 24 hour blockade around the main Televisa studios in Chapultepec, Mexico City.[85] On August 30 several protesters gathered outside the offices of the Electoral Tribunal of the Federal Judiciary as the Magistrates declared that the claims made by the left-wing coalition were "unfounded" and were therefore rejected.[86] Anti-Imposition Protest in Mexico City.
